Dear, I am using the ancillary files "N*_O3_AURAOMI_24h.hdf" and the 4 files "N*_MET_NCEP_6h.hdf. I am downloading from the Direct Data access (e.g. https://oceandata.sci.gsfc.nasa.gov/directdataaccess/Ancillary/GLOBAL/2022/365/). These ancillary files were all available until Decembe...

Dear,I am processing MODIS-Aqua L1 data to L2 phytoplankton abundance estimates based on Hirata and Uitz algorithms.In the l2gen products tab is also available one more algorithm called "KSM" but I can not find some reference to this methodology.Could you inform the article or authors of t...

Sean,

Thank you very much. The tips that you gave me resolved the problem.
My max_values were fixed in 18 Einstein m^-2 d^-1 and the region has a PAR higher than 60 Einstein m^-2 d^-1. I changed the max_values and the PAR pixels appeared!

Yours sincerely.

Norman,Thank you very much. The tips that Sean gave me resolved the problem.My max_values were fixed in 18 Einstein m^-2 d^-1 and the region has a PAR higher than 60 Einstein m^-2 d^-1. I changed the max_values and the PAR pixels appeared!And your scrip to count valid pixels is very useful, thank yo...

Dear,I downloaded some images from Level-2 MODIS-Aqua data to work with the PAR product, example:A2008114163500.L2_LAC_OC.ncA2007352171500.L2_LAC_OC.ncA2007044160500.L2_LAC_OC.ncWhen I opened using SeaDAS 7.x the chlor_a, chl_ocx, and other products have good pixels to work with. But the PAR product...
