Thank you for maintaining a great data portal. I am interested in using Giovanni AAOD data , and I wonder about the artificial division between the SH and NH apparent at the Equator for AAOD500 and AAOD388?
Any feedback on this would be great, thanks.

  1. The sharp gradient you have observed is associated with a hemisphere-dependent
    threshold in AIRS CO that we use in the aerosol type identification. That has
    been corrected in a new version of the OMAERUV  to be released soon. What
    period and region are you looking at?  If interested, I can make available to
    you gridded monthly values of the upcoming data.
