The CEOS CARD4L product guidelines asks to include the « Noise Power Image » in the ARD product. This raster shall be already available as an intermediate product of the Thermal noise removal step.
For info, from the CEOS CARD4L documentation (https://ceos.org/ard/files/PFS/NRB/v5.5/CARD4L-PFS_NRB_v5.5.pdf), the « noise power image » is defined as follow:
Estimated noise equivalent σo (or b0 or go, as applicable) used for
Noise Removal, if applied, for each channel.
This shall be quite straightforward to extract. Action is urgent - perfectly if available for 9.
