Dear developers,

after updating to SatPy 0.42.1 May 1st 2023 I found that the above mentioned composite does not work anymore. Under cron control I produce hourly images from GOES16 (area caribbean), MSG3 (area westminster) and MSG2 (area afghanistan) that worked flawless with 'true_color_with_night_ir_hires' before.

In addition I find a hell of a lot of warnings about time precision when imaging MSG3/2.

Any idea?

Hi,

could it be that this is related to


the generic image reader that reads in the the background image with artificial illumination?

Could you tell us what is actually not working? Error messages?

The warnings about time precision I think is an xarray warning message but I can't be sure without seeing it.

Try installing rioxarray package and see if that helps

Panu,

thanks for that. It seems to work again. Reading PR2432 yesterday I figured it has something to do with xarray.
So I *updated* xarray to the latest but with no avail. Now I have the following  three packages in env  (pytroll):

1) rasterio
2) xarray
3) rioxarray

@Martin does PR2432 mean that rasterio is now completely obsolete (replaced by rioxarray) and
can  be deleted? Is there a problem in SatPy 0.42.1 in that rioxarray is not automatically installed?

Best regards,
Ernst

P.S.
I let it now run under cron as usual for some days to see whether everything really works again.

Dear Ernst,

Thanks for reporting the issue!

rasterio is still required by rioxarray, so it can't be removed.
Moreover, rasterio is not a hard requirement for satpy, only optional,
and thus was not automatically installed in principle. So the same
applies for rioxarray...

Best regards,
Martin

Martin,

thanks for the explanation. I may be wrong but cannot remember to ever have installed rasterio as a separate package.
'true_color_with_night_ir_hires' is a nice composite that works for MSG, GOES and Himawari and is used by a couple
of people with my satpy scripts. I'll make a note about eventually missing rasterio and rioxarray in my documentation.

Remains the tons of warnings
...
/home/eumetcast/miniconda3/envs/pytroll/lib/python3.10/site-packages/satpy/readers/seviri_base.py:386: UserWarning: Converting non-nanosecond precision datetime values to nanosecond precision. This behavior can eventually be relaxed in xarray, as it is an artifact from pandas which is now beginning to support non-nanosecond precision values. This warning is caused by passing non-nanosecond np.datetime64 or np.timedelta64 values to the DataArray or Variable constructor; it can be silenced by converting the values to nanosecond precision ahead of time.
...
with MSG satellites. Is this something we should care about?

Regards,
Ernst

Ernst,

The warning should now affect the results of the processing. However, it is something we need to take a look at, so it would be nice if you could create an issue for it in satpy's github.

Best regards,
Martin

Ernst,

Sorry for missing those attachments. It looks like the conda-forge package for trollimage includes rasterio as a hard requirement:

https://github.com/conda-forge/trollimage-feedstock/blob/main/recipe/meta.yaml

which I don't remember doing, but is a happy accident in this case. This means that Satpy depends on trollimage which pulls in rasterio.

In the (near?) future, we hope to switch to rioxarray for writing geotiffs in trollimage and in that case we could update trollimage to depend on rioxarray instead of rasterio. That might solve this inconvenience on your end, but as you're probably already doing you can keep rioxarray as a package to be installed in your environment.

Dave
