Negative pixel size if area is flipped

8

#### Code Sample, a minimal, complete, and verifiable piece of code ```python from pyresample.geometry import AreaDefinition area_def = AreaDefinition( "test", "test", "test", projection={"proj": "geos", "lon_0": 0, "h": 35785831.0}, width=2, height=2,...

#### Problem description The bucket resampler tests use a target area of shape (2560, 2048) which makes unit testing difficult. If the area had a much coarser resolution, for example...

Add reader for GMS-5 VISSR data. This is still a work in progress: - No calibration yet, only counts. - Geolocation is pretty slow - Not compatible with dask, yet...

Make WavelengthRange importable from satpy.dataset

6

This PR makes the `satpy.dataset.dataid.WavelengthRange` class from importable from `satpy.dataset`. The [satpy internals docs](https://github.com/pytroll/satpy/blame/main/doc/source/dev_guide/satpy_internals.rst#L95) suggest that, but currently the import doesn't work.

HUGE_VAL vs NAN

26

Hi, I only know PROJ through pyproj, but as far as I can see PROJ uses `HUGE_VAL` (that means +Infinity) from math.h as a fill value whenever a projection operation...

Inf vs NaN

7

Currently pyproj returns `inf` whenever a projection operation fails, which is coherent with the behaviour of PROJ. However, I could see some benefits from changing this to `NaN`, see https://github.com/OSGeo/PROJ/issues/2376....

### What happened? `xr.where(..., keep_attrs=True)` overrides coordinate attributes of the result with global attributes from one of its inputs. ### What did you expect to happen? The coordinate attributes to...

Tiny difference in SEVIRI HRIT area extents

**Describe the bug** In some very rare cases, the area extent of a SEVIRI HRIT scene is a tiny bit different from the majority of scenes. ``` Majority, areas.yaml (5567248.28340708,...

Allow channel-specific calibration mode for SEVIRI

## Feature Request **Is your feature request related to a problem? Please describe.** Since https://github.com/pytroll/satpy/pull/2589 there are three calibration modes available for SEVIRI (Nominal, GSICS, Meirink). But currently it is...
