Hello, I am studing the satellite SO2 product, I am having some problems.
The nominal spatial resolution of OMPS-NM is 50 km × 50 km at nadir in the nominal observation mode.But at the edge of the swath, the pixel area will increase. and I tested it by 50 km × 50 km and compared it with the data on this website(https://so2.gsfc.nasa.gov/pix/special/2022/hunga/hunga_ompspca_so2stl_20220114.html), and the results were quite different.
Then,how can i obttain the area of each pixel for the OMPS SO2 product. how about TROPOMI SO2 product?
