@rmarquarlops Are you OK with this proposition?
In fact the code in xsarslc
to generate the tiles do not have yet the sigma0_filt
variable. (This evolution is foreseen in any case).
So for now we will continue with sigma0
and land_flag
. see https://github.com/umr-lops/xsar_slc/blob/0a200b7a84017ca32580ae0f303ff9134a4f490d/xsarslc/interface.py#L74
If we look at https://github.com/umr-lops/L2A-wind-direction-processor/blob/4a17e91f7442b146072f7d78768c4651e3f0d886/l2awinddirection/generate_L2A_winddir_pdf_product.py#L44 we can see that
sigma0
is used for the prediction. In the meatime the Level-1B product evolved and introduced asigma0_filt
variable with (denoising and bright target correction) also it is NaN for the tiles with land whilesigma0
in the latest version of the L1B product is always defined. So I suggest to replacesigma0
bysigma0_filt
.
