  2. What is SeaBASS? local archive for bio-optical data & related oceanographic / atmospheric measurements data contributed by research groups from 45 institutions in 15 countries data uses include: (1) satellite ocean color data product validation (2) bio-optical algorithm development (3) climate, time series, and merger studies 45,000 data files from over 1,600 field campaigns, as of January 2008, including: (1) 35,000 radiometric (AOP) stations (2) 65,000 pigment (CHL) stations (3) 20,000 spectroscopy (IOP) stations (4) 16,500 aerosol optical thickness (AOT) stations all data are accessible online: (1) publicly available via SeaBASS Web site (2) periodically released to National Oceanographic Data Center see also: (1) SeaBASS NASA Technical Memorandum211617, pp 45 (2002) (2) Werdell et al., EOS Transactions AGU84, 38 (2003) (3) http://seabass.gsfc.nasa.gov/ SeaDAS Training ~ NASA Ocean Biology Processing Group

  7. What is NOMAD? SeaBASS consists of original files from data collectors: radiometry,spectroscopy, pigments, and CTD all in separate files most data are depth-resolved  i.e., no surface (0-) values! lots of replicate data Realizing the difficulty in using these data for algorithm development, the OBPG: evaluated all SeaBASS radiometry, spectroscopy, pigments, and CTD estimated surface (0-) values from these data (used for validation!) identified coincident observations generated a consolidated, merged data set named this data set the NASA Marine bio-Optical Data-set (NOMAD) NOMAD is fully publicly available, as are its source data within SeaBASS: 3,467 coincident observations of Lw(), Es(), Kd(), & Chl Wt, Sal, bb(), and a() where available metadata includes date, location, & cruise name plus, NCDC OISST, NGDC ETOPO2, & processing flags Werdell & Bailey, Rem.
