Hello, I’m a bit confused about the meaning of these variables. Are both derived using the GIOP algorithm, one based on in situ Rrs and the other on satellite Rrs? Or is in situ adg_giop443 simply the measured absorption coefficient of adg, not an inversion result? In the validation results the in s...

Thanks for reaching out to us via the forum. I'm sorry to hear your emails aren't getting through to seabass@seabass.gsfc.nasa.gov which is normally the best way to contact all our data management staff. That email method appears to be operational, however, we will help diagnose why it isn't working...

Hello - there are portable match-up tools designed to help you find coincident satellite match-ups, and then extract data from the satellite files including match-up exclusion criteria QA/QC like described in Bailey and Werdell (2006) and on the SeaBASS Validation Description that you linked. They p...

I am not an expert on the manuscript you referenced, but here are a few thoughts to hopefully get you started. I believe the authors used Level-1B MERIS data, which you can find how to download from https://oceancolor.gsfc.nasa.gov/data/find-data/ . Either File Search, Level 1 & 2 Browser, or Ea...

Within OB.DAAC, SeaBASS is the right place to look for those sorts of in water measurements. SeaBASS has some of those measurements from inland lakes, although mostly marine measurements. There is no single search option to find lake-only datasets through the SeaBASS File Search , though, for exampl...

Can I get the Rrs (Sr^-1) by the following equation? Rrs = Lw1/Ed Sfc [As this is an insitu mesurement] You're correct. That approach to the in situ data of dividing water-leaving radiance by surface irradiance will appropriately provide you with Rrs (sr^-1). You might also wish to consider applyin...

Hello, The date and time information in the SeaBASS SST dataset (and all SeaBASS data in general) is in GMT/UTC, not local time. Since the dataset is global, if you wish to organize the data by specific local times, you will need to use a method to convert to local time. FYI in case it is helpful: N...

Thanks for bringing this to our attention, and I'm sorry for the inconvenience. We've identified and corrected an issue that was preventing a few recent datasets from being served properly, which included the EXPORTS radiometry files you were trying to order. The individual links for the affected fi...

Hi Zach, The file you asked about can be found in the documents bundle that comes as part of the order whenever you order at least one file from a particular cruise. FYI, all files listed in "/documents=" as well as "/calibration_files=" should be present in the relevant document...

FYI, some of the information you asked about can be found on, or supplemented with, SeaBASS's SST Validation Description Page. Regarding your questions: The surface depth or method for the in situ SST value depends on the source of the in situ data source used for validation, e.g., many are based on...
