Here is a view of channel 1 remapped to a near-ided perspective projection over northern Europe: 

So, just a comment/observation. The AWS testdata file delivered August 2023 has the datasets structured a bit odd and different from most other satellite datasets (e.g. the EPS-SG MWS testdata...

I somehow thought we had merged this long ago? But, it makes sense not to merge it now, as we will have new test data from ESA in about a...

While working with this PR and upgrading our systems for NOAA-21 at SMHI we realized that there seem to be a bug here, standing in the way of updating support...

> I copied the two lines to `noaa21.tle` file, pointed `PPP_CONFIG_DIR` to directory of my `platforms.txt` where I added `NOAA-21 54234`. After this > > ```python > from pyorbital import...

@davidh-ssec @mraspaud and @pnuu : Any comments on where we could/should add a landuse or land-sea mask dataset, and its handling? It could used for other purposes than atmospherci correction...

What you calculate is a reflection - the contribution to the observed due to Rayleigh scattering and aeorosl absorption. The units are in percent (`%`). I realize that is not...

If you assume the target is a a true blackbody at 3.7 micron the reflective part is zero, and then it is a simply convolution of the spectral response function...

The you can derive the brightness temperature at any particular wavelength like this: ``` In [16]: from pyspectral.blackbody import blackbody_rad2temp as rad2temp In [17]: rad2temp(3.7*1e-6, m12rad['radiance']) Out[17]: array([279.71581719]) In [18]:...

But all this is neglecting the impact of the atmosphere, it derives so to speak the upwelling Tb at the surface. If you want to simulate the TOA Tb you...
