This PR adds a series of RGB composites for FCI. In most cases, the new RGBs reuse existing recipes, and will have to be tuned further to account for the specific FCI properties (SRF, resolution, etc).
It adds the composites:
night_ir105
for a simple nighttime layer to be used to fill the night-time part in day-only RGBs (see below). This was used for the EUMETSAT FCI first image and commissioning publications.night_ir_alpha
, as well as the accordingnight_ir_with_background
andnight_ir_with_background_hires
, as known from e.g. SEVIRItrue_color_with_night_ir105
,true_color_with_night_ir
,true_color_with_night_ir_hires
, combining True Color with the night layers abovecloud_type
,cloud_phase
and for each a day-night combination usingnight_ir105
(cloud_*_with_night_ir105
)ir_sandwich
, based oncolorized_ir_clouds
, as well as the day-night combinationir_sandwich_with_night_colorized_ir_clouds
. Uses the same recipe as in SEVIRI, with the spectral colormap.fire_temperature
, with the classic recipe, plus the variants_38refl
with the reflective part of the 3.8µm channel and_rad
with the channels in radiance units (here, the stretch limits have been computed by converting the radiance unit of the existing recipe limits)snow
, since the according composite invisir.yaml
is not being picked up due to the VIS0.8 channel starting only at 0.815, while the dependency looks for 0.824h_microphysics
, which was missing completely in satpy, and is hence added tovisir.yaml
, using the standard EUM recipe from https://resources.eumetrain.org/RGBguide/recipes/RGB_recipes.pdfBy doing this, it contributes in several ways to #2670. To close that issue, we still need to sort out a few midlatitude/tropical recipes: since this affects many shared recipes and is not specific to FCI, I would leave that to a different PR.
After this PR, the list of available composites for FCI becomes:
