Using IOP models with simulated water reflectances

Thanks, Sean.  One question:

"...for now it'll work for "SeaWiFS" like inputs."

Just to clarify, does that mean I must specify only SeaWiFS rrs_XXX wavelengths in my SeaBASS input file?

Best,

OCSSW built problem: third-party sources (sdptk) compilation hangs

Thanks everyone for the quick response. Yes, I have gfortran installed (I would not have gotten very far without that ;-)) . But I didn't realize that Apple's gcc/g++ didn't play will with others.  I have Macports installed, so I'll follow Sean's suggestions.(It's still ...

OCSSW built problem: third-party sources (sdptk) compilation hangs

I am trying to rebuild l2gen with OCSSW_DEBUG=ON. So, first I must build the third party sources at occsw/opt/src (doing this with OCSSW_DEBUG=OFF).I am following the build instructions at https://oceancolor.gsfc.nasa.gov/docs/ocssw/1. I downloaded the latest code$ cd $OCSSWROOT/opt$ wget https://oc...

Using IOP models with simulated water reflectances

Thanks Sean.  Updated my occsw data processors (MacOS 10.14.5 / Mojave) to latest release, but l2gen is throwing an error somewhere...(Note that I am not specifiying rrs_469, rrs_555, rrs_645 in my SeaBASS file.  Is that the problem?)  My input file is hyperlinked to Google Drive so y...

Using IOP models with simulated water reflectances

I would like to use l2gen to create IOP estimates (from GIOP, GSM, QAA algorithms) using my own (simulated) normalized water-leaving reflectances ?^N_w= pi*Rrs, not TOA values.  How can I do this?  I see that I can turn off atmospheric correction (atmocor = 0), but I believe Rayleigh corre...

Pixel Area, L3b ISIN grid

Thanks Sean.  Yes, I saw that text in Vol 32.  I hoped someone had already done the calculations and could share them with me. :eek:

Pixel Area, L3b ISIN grid

Has someone computed the corrected pixel area per row (or bin) for SeaWiFS and MODIS 4.64 km and 9.28 km ISIN grids?  I'm looking for the result that takes into the variation of pixel size due integerization of the number of pixels per row, including the special pie-shaped sectors at the po...

Question: Reprojection onto ISIN grid

Reprojection onto ISIN grid

For various reasons, I would like to spatially bin products using the SeaDAS (equivalently GPT) Level-3 Binning, and then reproject onto an ISIN grid.  For example, I would like to spatially bin (AVERAGE pixels) from 4.6 km to 9.3 km resolution, then rewrite as a normal 9.3 km ISIN (e.g., SeaWi...
