We download the MODIS L0 files from ocean color and the L0 files were processed to L1B by SeaDAS 8.1.0. Then the L1B files were processed by l2gen to get the Rayleigh corrected reflectance products. However, we find that the subset function of l2gen (like north=31.8 sourth=30.5 west=119.6 east=121.5) does not work. THe output Rayleigh products were the whole image (not subset).
How can we get the subset image?
