some questions about L2GEN
Hello everyone,In Seadas L2GEN,Products--Atmospheric correction Intermediates,a parameter 'w0' refers to the aerosol single scattering albedo? and what do 'w0_sma','w0_soa' refer to ,respectively? Because I want to use 'single scattering albedo' provided by various of...

ask some quesitons about AOT and Angstrom Exponent
Dear Sean,
Thank you so much for your help!
So, you mean the NASA GOCI L2 products(GW method with Bailey(2010)) using the same method with using l2gen----aer_opt----choose '-2- Multi-scattering with 2-band,RH-based model selection and iterative NIR correction' ?
Best Regards.

ask some quesitons about AOT and Angstrom Exponent
Dear Sean,Thank you for your always reply!1. I haved download GOCI L2 products from this site. But I found there are some negative values for Rrs(660)?Rrs(680) even in open oceans.What's the reason?2. These GOCI L2 products generate using Gordon and Wang method or your method(Bailey,2010)? ...

ask some quesitons about AOT and Angstrom Exponent
Hello everyone?To my understand?when the bands increase?then the AOD decrease.And?the range for Angstrom Exponent is from 0 to 2.But recently?I have used seadas to generate GOCI L2 products using NIR iterative method?Bailey?2010??and match them up with Microtops which measure AOD. But in China yello...

white aerosol ?
Dear Sean,
You means it refers to 'UV-AC' algorithm(atmospheric correction using ultraviolet wavelength) which is provided by Xianqiang He(2012) ?

atmospheric correction algorithms for level 2 products for sensors
Dear Sean,Thank you for your help!To my understand, L2 products downloaded from oceancolor use standard atmospheric correction(NIR method).Is it right?I have another question:I have downloaded several days of MODIS/Aqua L1B products , and then I'd like to use l2gen to generate L2 pro...

atmospheric correction algorithms for level 2 products for sensors
Hello everyone,1. I have downloaded L2 products?including Rrs?. But what's the atmospheric correction algorithms used in SeaDAS to generate L2 products for MODIS/Aqua?GOCI?VIIRS?2. Why GOCI do not have data between Aug.15,2017 to Aug.26,2017 in https://oceancolor.gsfc.nasa.gov/? Are...
