Question: In-situ data
Replies: 1

Re: In-situ data

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...

Question: Conversion of WL radiance to reflectance in MOBY data
Replies: 2

Re: Conversion of WL radiance to reflectance in MOBY data

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...

Question: SST algorithms performances at night

Re: SST algorithms performances at night

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...

Re: files not downloaded in request

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...

Re: Calibration files in associated documents

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...

Re: Co-located SST data set

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...

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

Hello,Regarding 1) Yes, you can constrain your search as you described, if I understand your question correctly. The Validation Search form includes lat/lon/time options which allow you to focus on results within your specified constraints. You will also need to check all the “Products” boxes (n...

Question: Remote Sensing Reflectance
Replies: 3

Remote Sensing Reflectance

1. There are a variety of instruments, such as profiling radiometers, floating/tethered radiometers, and above-water radiometers (mounted on a fixed platforms or ships, and those that are handheld.) It is difficult to generalize about their quality and priority of use, since it’s possible to collect...

Remote Sensing Reflectance

Hi Liu,1. For NOMAD and SeaBASS validation, SeaBASS staff have typically calculated Rrs from in-water profiles (see: Werdell and Bailey, 2005, and Bailey and Werdell, 2006). Yes, Ed(0+) and Es are synonyms, and both mean spectral downwelling surface irradiance. In NOMAD it is named Es, though there ...

File search and Validation search problem

Hi Liu,The site should work with Chrome, and I've tested that latest version successfully, so I suspect there might be something off in your settings. Is Javascript disabled in Chrome? That could cause issues similar to what you described. Check Chrome's menu -> Settings -> Site Settings -> ...
