Summary
Abstract:
This data set consists of satellite measurements of global ocean sea surface temperature (SST) data obtained by the Moderate Resolution Imaging Spectroradiometer (MODIS), in orbit on the Aqua (formerly EOS PM) platform. MODIS SST products are processed and distributed by the Ocean Biology Processing Group (OBPG). The generation of SST products from the MODIS sensors is performed using the ... Multi-Sensor Level-1 to Level-2 software (MSl12), based
on algorithms and logic originally developed by the Rosenstiel School of Marine
and Atmosphere Science (RSMAS) at the University of Miami. Processing details
can be found at http://oceancolor.gsfc.nasa.gov/DOCS/modis_sst/
Each Aqua MODIS Level-3 binned (4 km) data product consists of the accumulated
data for all Level-2 products, for the specified instrument and resolution,
corresponding to a period of one day, 8 days, a calendar month, a season, a
calendar year, or the cumulative mission. Each Level-3 binned data product is
stored in one or more HDF files. The data are stored in a representation of a
global, equal-area grid whose grid cells have a resolution of 4.6x4.6km.
Each given time binning period (Daily, 8-Day, Monthly, Monthly Climatology,
Seasonal, Seasonal Climatology, Annual, Cumulative) has a separate file for
each product. These files include a main file containing all product-level
metadata, and data for each bin filled for that product and time period.
Aqua MODIS SST binned products consist of:
NSST = Sea Surface Temperature - 11 micron (nighttime)
SST = Sea Surface Temperature - 11 micron (daytime)
SST4 = Sea Surface Temperature - 4 micron (nighttime only)
More detailed information on the Level-3 binned data product format
specifications can be found in the document at

WARNING: EP TOMS started experiencing calibration problem since 2002. For data beginning in year 2000, the calibration has been stabilized relative to NOAA-16 SBUV/2 in the equatorial zone. Because of continuing changes in the optical properties of the front scan mirror that are not well understood, data are showing a latitude dependent error that cannot be corrected by a simple calibration correction. The calibration appears to be stable near the equator. But by 50 degrees latitude, there is now a -2% to -4% error in TOMS, a bit larger in the northern hemisphere than in the southern hemisphere. Because of this error, data since 2002 should NOT be used for trend analysis

Earth Probe TOMS data since 2002 should NOT be used for trend analysis because of the calibration problem.
