Hello,
   I have a question about  MODIS L1/L2 data. Is it possible to use MODIS 250m data to derive L2 (Rrs, Rhot, Ch-a, and SST)?  Would SeaDAS/OCSSW/l2gen work for that?
Thank you.

Hello,  I am trying to download Sentinel 3 OLCI EFR (L1) data from the OceanColor Level 1 & 2 Browser . It works fine with Sentinel 3A but not for 3B.  I use 'Order Data' and expect to get a list of URLs to download data -- this works for 3A but I keep seeing  'Redirec...

Thanks much Sean.I am  running l2gen for HICO  on  SeaDAS GUI. I see the absc_gas.nc file on my Mac in /seadas-7.5.3/ocssw/share/hico directory.I moved the file to /seadas-7.5.3/ocssw/share/common where atrem_angle_limit.nc is and just got read before I get the 'No such file or di...

Hello,   I am using l2gen to get HICO L2 data.  My question is about 'Derived Geophysical Parameters'. Are all the options valid for HICO? Also, I see multiple algorithm options for certain parameters -- e.g. Kd 490, sst, Zsd (Sechhi Depth).  Is there any default recommen...

Thanks Norman. I have another question I'd appreciate help with. I have installed OCSSW to process  a number of sensors. If I add a new sensor, do I have to re-install it for all the sensors? To be specific I installed OCSSW for MODIS, OLCI, OLI, MSI. Now I want to add VIIRS and HICO -- so ...

Hello,    I am trying to match  pixel location in  OLI, OLCI, and MSI Level-2 image with in-situ data. I colocate according to latitude-longitude of the in situ point measurements data and the lat-lon arrays available in the L2 images. My question is, do I have to re-project the ...

Hello,
     I have a question about l2gen output file. In the L2 netcdf output file I see longitudes slon, clon, and elon. And similar for latitude. I use clon and clat of each pixel as geolocation of that pixel when using in calculations. Is this a correct assumption?
Thanks.

Hello,  I use SeaDAS GUI on my Mac for raster calculations and visualization.  I am trying do the same on a Linux computer. When I launch 'seadas'  I get the following message window: "An Internal Error occurred. Not able to create user interface control for page componen...
