The MODIS data are available in a variety of spatial resolutions and temporal periods. The Level 3 mapped products are global gridded data sets with all points filled even over land. The Level 3 mapped files are derived from the Level 3 binned files.
"The Scan Mirror Assembly uses a continuously rotating double-sided scan mirror to scan +/- 55-degree driven by a motor encoder built to operate at 100 percent duty cycle throughout the 6-year instrument design life. The optical system consists of a two-mirror off-axis afocal telescope which directs energy to four refractive objective assemblies; one for each of the VIS, NIR, SWIR/MWIR and LWIR spectral regions covering a total spectral range of 0.4 to 14.4 um.

The data are then sent to the EOS Data and Operations System (EDOS) at the Goddard Space Flight Center. After Level 0 processing at EDOS, the Ocean Biology Processing Group (OBPG) produces the Level 1A, Level 1B, geolocation and cloud mask products. Higher-level geophysical products are also produced by the OBPG. The JPL PO.DAAC is acting as a mirror site for MODIS Level 3 SST products distributed by the OBPG.
