Algorithm Theoretic Basis Documents, Product Specification Documents & User Guides
Up-to-date information is posted on the LP DAAC product pages. Please click the link for documentation, including algorithm theoretical basis documents (ATBD), product specification documents (PSD), and user guides. Also pay attention to “Known issues” listed near the bottom of the page.
Some products are available in multiple formats. For instance, L2_LSTE is land surface temperature and emissivity in swath format, distributed as HDF5 (to be used with L1B_GEO); L2G_LSTE is land surface temperature and emissivity that has been projected onto a 70 m grid, distributed as HDF5; and L2T_LSTE is land surface temperature and emissivity that has been gridded and tiled into smaller chunks (~100 km x 100 km following the Sentinel tiling boundaries) and distributed as GeoTIFF.
