Python package for earth-observing satellite data processing

Last update: Dec 27, 2022

Overview

Satpy

The Satpy package is a python library for reading and manipulating meteorological remote sensing data and writing it to various image and data file formats. Satpy comes with the ability to make various RGB composites directly from satellite instrument channel data or higher level processing output. The pyresample package is used to resample data to different uniform areas or grids.

The documentation is available at http://satpy.readthedocs.org/.

Installation

Satpy can be installed from PyPI with pip:

pip install satpy

It is also available from conda-forge for conda installations:

conda install -c conda-forge satpy

Plotting day night composite satellite image

Hi I would like to know what is the proper syntax for plotting day night composite satellite image. My intention is to first create a day night composite and then view the day night composite image of earth. Then from the earth image I want to further crop it to a specific region. But I keep getting the error as seen below:

Add parallax correction via new `ParallaxCorrectionModifier`
Add a parallax correction to Satpy.

This is a team effort based on work by Simon Proud (@simonrp84), Xin Zhang (@zxdawn), Ulrich Hamann (@uhamann), Jussi Leinonen (@jleinonen), myself, and others.

We have made good progress during the Pytroll Contributor Week 29 November - 3 December 2021. More work was done in December 2021 and January 2022.

[x] Closes #1845

[x] Tests added

[x] Fully documented

[x] Add your name to AUTHORS.md if not there already

[x] Add more tests where

source and target resolutions are very different

areas are only partly overlapping

areas are not overlapping at all

areas are the same

[x] get reliable reference values for unit tests where this value is not trivial

[x] Investigate if other resamplers resolve the problems at poles and antimeridian

[x] Make resampler and search radius configurable

[x] Add easy to use modifier interface

[x] Get orbital parameters from somewhere else than the metadata of the CTH dataset. This information is not included with nwcsaf-geo and arguably should come from the dataset to be corrected, not from the CTH (which theoretically doesn't even need to come from the same satellite). See https://github.com/pytroll/satpy/pull/1904#issuecomment-1010037925.

[x] Make sure heights are in metre

[x] Add test to cover the case where clouds are moved out of the area of interest completely.

[x] Improve speed (although there are no formal performance tests yet, small tests show the correction is very slow).

[x] Fix bug when loading corrected and uncorrected datasets simultaneously.

[x] Check why brightness is different for parallax corrected image and fix this.

[x] Make internal resampling of CTH more flexible (rather than hardcoding method and parameters)

[x] Make resampling in modifier more flexible, actually using the provided parameters.

Deferred:

[ ] Not critical: implement checks for warning or error if areas do not or only partially overlap. This relies on https://github.com/pytroll/pyresample/issues/329 to be fixed first. Without those checks, applying parallax correction may yield unexpected results.

[x] Add diagnostic tool to get the displacement (distance & direction)

[ ] Expose and document interface to intermediate swathdefinition as public API

[ ] Add test for when parallax correction shifts a cloud across the antimeridian or pole (or document that this is not supported)

[ ] Allow explicitly passing satellite location for datasets where this information is not included (either when no information provided at all, or when estimate based on TLE and skyfield is undesirable)

[ ] Allow obtaining satellite location or viewing angles from the metadata not only of CTH but also of other datasets. This would require those to be passed to the modifier as optional prerequisites.

[ ] Add performance tests (in benchmark directory?) with real scenes (could be a different PR)

[x] Check dask-awareness

[ ] Check/control for what area parallax is calculated when scene is resampled, but modifier interface is used

[x] Confirm that dask reuses calculations, such as when multiple channels are corrected

[ ] Check if further optimisations are needed for multiple channels, such as avoiding recalculating the dask graphs

Add `get_area_def` to cf reader
This adds add area definition support for the cf reader. I fixed the tests and added a test area in geos projection as well as some preliminary assertions for testing the area. I think the tests should be improved and extended to cover other areas. Currently the extent assertion is failing because of https://github.com/pytroll/pyresample/issues/355.

MTG: get projection and extent information from file
In the MTG FCI FDHSI L1C reader, get the projection coordinates and extent information from file. For the projection coordinates, get those from /data/mtg_geos_projection rather than from /state/processor, as is consistent with the documentation. The extent information was previously hardcoded but now obtained from data/channel/measured/x and data/channel/measured/y, which contain this information in radians. This commit fixes #840 although there are still some issues with the resulting image that need to be resolved.

AHI HRIT reader has gotten slower
Describe the bug Compared to older versions of Satpy, the ahi_hrit reader seems to have gotten very much slower.

To Reproduce

Create an environment with Satpy 0.19.1.

Create an environment with Satpy 0.23.0.

Compare the timings creating the same set of composites, e.g. by running the below script and composite definition. The built-in composite needs to be overridden, as it isn't consistent over these versions.

#!/usr/bin/env python import glob import os os.environ['PYTROLL_CHUNK_SIZE'] = "1024" os.environ['DASK_NUM_WORKERS'] = "2" os.environ['OMP_NUM_THREADS'] = "1" import time from satpy import Scene def main(): fnames = glob.glob( "/home/lahtinep/data/satellite/geo/himawari-8/IMG*20201001070*") comps = ["truecolor",] glbl = Scene(reader='ahi_hrit', filenames=fnames) glbl.load(comps) glbl.save_datasets(base_dir='/tmp/') if __name__ == "__main__": tic = time.time() main() print("Elapsed time:", time.time() - tic)

in $PPP_CONFIG_DIR/enhancements/ahi.yaml

truecolor: standard_name: truecolor operations: - name: cira_stretch method: !!python/name:satpy.enhancements.cira_stretch

Expected behavior Similar timings for the old and new versions. The other chains I've upgraded over the same versions have actually gotten faster. For the full set of composites I got processing times (via Trollflow) of around 10 minutes. With the new version(s) the process crashes around 28 minutes when the memory runs out.

When saving to CF prepend datasets starting with a digit by CHANNEL_
In NetCDF CF variables should not start with a digit.

Some channels, like AVHRR, are just named by a number and this number is used as the dataset name. When saving to NetCDF cf the PR prepend CHANNEL_ to each dataset starting with a digit so the variables in the resulting NetCDF CF file does not start with a digit, but instead CHANNEL_<original_dataset_name>

Make the metadata keys that uniquely identify a DataArray (DataID) configurable per reader
This is an attempt at making DatasetIDs dynamic.

DatasetID objects are used in Satpy to index datasets in a Scene object. They are namedtuples that contain a fixed set of properties that we considered a common denominator for all datasets readable by Satpy. However, it has been shown on multiple occasions that it is becoming harder to make all the properties relevant for all the datasets. For example, polarization and level are such properties that only apply to one dataset type each (respectively SAR-C and Geocat). At the same time, more dataset types are coming into Satpy that need new properties, eg SLSTR which has nadir and oblique views that we need to include in the DatasetID if we want to discriminate the datasets efficiently.

To avoid having to extend the set of properties needed to identify all datasets in Satpy, I propose here to make the DatasetID objects dynamic in that the set of properties they use to identify datasets can be tuned per reader. At the same time we are still able to compare DatasetIDs from different datasets. Moreover, properties that are irrelevant to a given dataset are now omitted entirely. For example, wavelength doesn't make sense for a longitude dataset, and hence will not be a part of the DatasetID needed to identify longitude, even if the reader configuration defines it as a possible property for idenfying datasets.

For backwards compatibility, a default DatasetID is still available, but hopefully should be removed soon.

FCI L1c reader is single threaded

Describe the bug While working on https://github.com/pytroll/satpy/pull/2182 and debugging the slow-down it caused, I noticed that the current implementation of fci_l1c_nc reader is single-threaded until the writing starts.

To Reproduce

import glob
import datetime as dt
import os
os.environ['DASK_NUM_WORKERS'] = "4"
os.environ['OMP_NUM_THREADS'] = "1"
os.environ['GDAL_NUM_THREADS'] = "4"
from satpy import Scene
from dask.diagnostics import ResourceProfiler, Profiler, CacheProfiler, visualize

def main():
    fnames = glob.glob(
        "/home/lahtinep/data/satellite/geo/fci_2022_uncompressed/RC0067/*nc"
    )
    comps = ["ir_105",]
    glbl = Scene(reader='fci_l1c_nc', filenames=fnames)
    glbl.load(comps, generate=False)

    lcl = glbl.resample("euron1", resampler="gradient_search", reduce_data=False)
    lcl.save_datasets(base_dir='/tmp/', tiled=True, blockxsize=512, blockysize=512, driver='COG', overviews=[])


if __name__ == "__main__":
    with Profiler() as prof, ResourceProfiler() as rprof, CacheProfiler() as cprof:
        main()
    visualize([rprof, prof, cprof],
              filename=dt.datetime.utcnow().strftime('/tmp/profile_fci_%Y%m%d_%H%M%S.html'),
              show=False)

Expected behavior Adjusting the DASK_NUM_WORKERS variable should affect the CPU usage. In the above example, the CPU load should be around 400 % for most of the processing.

Actual results Only the GDAL_NUM_THREADS variable has any effect. This would indicate that only the writing part is happening in parallel.

Update SEVIRI native reader with 'time_parameters' metadata
Edit: The original purpose of this PR has changed. Originally it switched the native reader to use the observation time for the generic start and end time, but since its original creation a new "standard" has been described to use nominal time for the start/end time and put all time metadata in a special time_parameters subdictionary of .attrs.

Original Description:

The SEVIRI HRIT and NAT readers are currently inconsistent with their start/end time values:

from satpy import Scene scn = Scene([my_nat_file], reader='seviri_l1b_native') scn.load(['IR_108']) print("NATIVE") print(scn['IR_108'].attrs['start_time']) print(scn['IR_108'].attrs['end_time']) scn = Scene(my_hrit_files, reader='seviri_l1b_hrit') scn.load(['IR_108']) print("HRIT") print(scn['IR_108'].attrs['start_time']) print(scn['IR_108'].attrs['end_time'])

Gives:

NATIVE 2021-11-09 12:00:10.388905 2021-11-09 12:15:10.076995 HRIT 2021-11-09 12:00:10.388000 2021-11-09 12:12:43.089000

This is because the HRIT reader selects:

['ImageProductionStats']['ActualScanningSummary']['ForwardScanStart'] and

['ImageProductionStats']['ActualScanningSummary']['ForwardScanEnd'] from the trailer / epilogue.

The NAT reader, though, selects:

['ImageAcquisition']['PlannedAcquisitionTime']['TrueRepeatCycleStart'] and

['ImageAcquisition']['PlannedAcquisitionTime']['PlannedRepeatCycleEnd'] from the header.

In this PR I update the NAT reader to select the same start/end time values as the HRIT reader uses. With the PR, the output of the above code snippet is:

NATIVE 2021-11-09 12:00:10.388000 2021-11-09 12:12:43.089000 HRIT 2021-11-09 12:00:10.388000 2021-11-09 12:12:43.089000

Fix ancillary variable confusion after resampling
Fix ancillary variable confusion after resampling.

Previously, replace_anc() was only looking at _satpy_id_keys in the variable attributes. When this was not set, it would use None for constructing the DataIDs used for comparison. When we pass None as ID keys to DataID, the DataID becomes empty: DataID(), such that a comparison always evaluates to True. As a consequence, instead of replacing the "correct" of N ancillary variables, it would replace the first one N times and the other ones not at all.

In this PR, I am taking the default_id_keys_config if no _satpy_id_keys are set in the variable attributes.

I'm not sure if _satpy_id_keys is supposed to be always set (possibly to default_id_keys_config, or if it is expected that it is not always set.

Default name and modifiers properties for modifiers
Feature Request

Even though manual application of a modifier for example the SunZenithCorrector might be an unusual use case, the name and modifiers init kwargs should be set by default for modifiers (normally these get set during loading from the yaml configs) . This would make attributes more consistent.

Currently this has to be set by the user like so:

from satpy.modifiers import SunZenithCorrector szen_corrector = SunZenithCorrector(name="szen_corrector", modifiers=("sunz_corrected",))

Ideally the user can just initialize it like this (also because the above behaviour is not documented)

szen_corrector = SunZenithCorrector()

Fix DataID overwriting attributes during Scene assignment and DataID not reflecting DataArray attributes
This PR fixes the overwriting of attributes of the DataArray to be assigned based on the DataID when writing to an existing id as well as the DataID not reflecting array attributes (see corresponding issues below).

The behaviour makes some assumptions which I think make sense but should be debated:

If name is not in the attributes it gets added based on the choosen name in the key to which the DataArray is going to be assigned

This deprecates the possibility to assign plain numpy arrays to the Scene and instead converts it to a xarray DataArray (I think this makes sense because many features of the Scene are based on attributes and as far as I can see not even the documentation mentions that this is possible).

A new DataID is generated from the DataArray attributes which also updates the _satpy_id attribute so they are in sync.

Currently not used but also the name property of the DataArray is set to the name in the DataID. This is something that needs to be discussed since it would be good if the name property also gets set by the readers and also, I think, they need to be unique which is not handled currently (e.g. what happens with two datasets in the Scene with DataID(name='1') and DataID(name='1', resolution=2000) ).
