definitions of SST from MODIS and VIIRS
Posted: Tue Feb 13, 2018 11:15 am America/New_York
I'm trying to get clear definitions of the L3 mapped SST products provided by MODIS and VIIRS. Can anyone verify the tentative ones below?
MODIS
NSST_sst: Nighttime SST computed from MODIS bands 31 (10.780–11.280 um) and 32 (11.770–12.270 um)
SST4_sst4: Nighttime SST computed from MODIS bands 22 (3.929–3.989 um) and 23 (4.020–4.080 um)
SST_sst: Daytime SST computed from MODIS bands 31 (10.780–11.280 um) and 32 (11.770–12.270 um)
VIIRS
SNPP_NSST_sst: ? Nighttime SST computed from VIIRS bands M15 (10.26–11.26 um) and M16 (11.54–12.49 um)?
SNPP_SST3_sst_triple: ? Nighttime SST computed from VIIRS bands M15 (10.26–11.26 um), M16 (11.54–12.49 um), and M12 (3.61–3.79 um)?
SNPP_SST_sst: ? Daytime SST computed from VIIRS bands M15 (10.26–11.26 um) and M16 (11.54–12.49 um)?
Huge thanks for any confirmation/correction! Not sure if it's just me but this basic info has been difficult to pull, e.g. because references to VIIRS are apparently missing from the data format specs (https://oceancolor.gsfc.nasa.gov/docs/format/#3M) and largely missing from the Ocean Level-3 Binned Data Products document (e.g. not in Table 2), and several "MODIS only" notes I think need to be updated to "VIIRS and MODIS only" at https://oceancolor.gsfc.nasa.gov/atbd. For anyone else looking, the clearest descriptions I have found are in Tu et al. (2015) (http://dx.doi.org/10.3390/rs71215881) and a VIIRS SST ATBD at www.star.nesdis.noaa.gov/jpss/documents/ATBD/D0001-M01-S01-010_JPSS_ATBD_VIIRS-SST_A.pdf.
