pixel radiometric accuracy

[CzendaZdenda]

Hi all,
Thank you for the Process_SMOS_L1C! I have a question about accuracy. Why calculated radiometric accuracy (RA) is about twice bigger than the original one (PixelRadiometry_acc)?

Hi @CzendaZdenda , thanks for the question.
The calculated Radiometric Accuracy it takes into account the "Radiometric_Accuracy_Scale" factor (normally 50K) which you find in the .HDR files. Thank factor is used to calculate the Radiometric accuracy and then it is also translated from XY to HV reference coordinate system. I guess that is the origin of the difference you spotted.
