Correct bbw values

Hello Bryan, In the MODIS/VIIRS ST meeting a few days ago you mentioned that a bug in bbw values led to them being a few nm off. Are the values available here now OK/corrected: https://oceancolor.gsfc.nasa.gov/reprocessing/r2009/sources/water_coef.txtIn particular, I'm using values as given in t...

Band-filtering applied to Rrs

Hi Dirk, Thanks for the fast reply, and pointing me to that reference. I also thought about convolving with each sensor's SRF, but I remember a prior discussion here stating that Rrs has been corrected to a uniform 11nm top hat bandpass, except MERIS:https://oceancolor.gsfc.nasa.gov/forum/oceanc...

Band-filtering applied to Rrs

Hello, I know this was discussed and answered a long time ago, but with the current Rrs NASA OBPG data, is all Rrs NASA data from all sensors processed to the equivalency of a 11-nm tophat band-average filter, centered on each nominal sensors wavelength? I.e. if I wanted to compare to modeled or mea...

Validation search in SEABASS with user input lat/lon/time

Hello, Is there a way on the SeaBASS website to do a validation search in the following ways: 1) User inputs a set of lat/lon/time values (where their in-situ data is) and system returns all satellite Rrs values matched (or another satellite value, say POC), controlling the criteria as in the existi...

Loisel and Stramski algorithm application to other sensors

Hello, Regarding the Loisel and Stramski IOP code as implemented in SeaADS:https://oceancolor.gsfc.nasa.gov/docs/ocssw/las__iop_8c_source.htmlI was wondering what your approach is to apply the algorithm to sensors other than SeaWiFS, as the original code coefficients are provided for SeaWiFS only. T...
