From the PUM of Sentinel-5P there is the following flag:
geolocation_flags in NO2/PRODUCT/SUPPORT_DATA/GEOLOCATIONS
Additional flags describing the ground pixel, including the influence of a solar eclipse, the possibility of sun glint, whether we are in the descending part of the orbit, whether we are on the night side of the orbit, whether the pixel crosses the dateline (useful for plotting), or if there was some geolocation error.
If I understood correctly if geolocation_flags = 2 it means that there is a possible sunglint measurement. Is it possible to restrict pixels with sunglint=2 using HARP? I want to plot only the pixels with possible sunglint effects.
