Fix using cached LUTs in bilinear resampler

10

This PR fixes the bilinear resampling when the resampling LUTs have been cached. The bug were introduced in #324 where a check was added to make sure the data array...

#### Problem description The unit tests, especially for bilinear resampling, are mostly duplicate code in two different classes. I think the tests should be refactored, clarified and simplified. While at...

#### Code Sample, a minimal, complete, and verifiable piece of code ```bash pytest pyresample/test/test_geometry.py ``` #### Problem description The usage of `pyproj.transform` has been deprecated. This function is used in...

Duplicate data when resampling to Eckert IV projection and area spans 180th meridian

Differences in resampling coverage when area crosses 180 deg longitude

17

**Describe the bug** It seems that there are differences in the resampling results between `satpy` `maint/0.8` branch (non-xarray/dask) and current `master` branch of `satpy` when the target area crosses 180...

FCI L1c reader is single threaded

31

**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**...

Update FCI L1c reader to work with remote file systems

4

This PR adapts the FCI L1c reader so that it is able to read data from remote locations using `fsspec`. ```python fnames = ["simplecache::s3://satellite-data-fci-test-data-2022/*DEV_20170920112*.nc"] scn = Scene(reader='fci_l1c_nc', filenames=fnames) scn.load(['ir_123']) scn.save_datasets()...

Lazy saving to NetCDF4 fails randomly if an array is used multiple times

1

### What happened? Saving `xr.Dataset()` lazily to NetCDF4 (`dset.to_netcdf(..., compute=False)`) fails seemingly randomly if an array is used either as a coordinate to multiple variables, or saved with different names...
