l2gen MOD02/MYD02

Have you rebooted the system or logged in to a new session since l2gen was last working?   A new login generally resets environment variables, so it is possible some variables are being set incorrectly and the l2gen that fails is an old version or you have the right version but it are usin...

VIIRS chlor_a noise/dropout lines
