Dear SentinelHub team,
I wanted to reproduce the variables “viewAzimuthMean” and “sunAzimuthAngles” from Sentinelhub using Sentinel-2 L2A data.
According to the metadata file, sunAzimuthAngles seems to have 23 x 23 values while each value covers an area of 5000 x 5000 meters.
It is bigger than the general band extent and needs to get cropped in order to get calculated together with the bands as far as I understood.
According to here the variable viewAzimuthMean seems to have a resolution of 5000x5000m as well, so it also consists of 23 x 23 values. Looking at the metadata files, there is information on viewAzimuthMean for each band and for so called detector id’s. Thus, I do not know how one mean value per 5000x5000m pixel was calculated. Even if you would have taken the mean value of the Mean_Viewing_Incidence_Angle_List (see a random metadata file MTD_TL.xml), the question arises whether you took the mean over all bands and used that value for the whole Sentinel-2 tile.
I hope my question is not too complicated to understand.
