MODIS/Aqua Land Surface Temperature/3-Band Emissivity 5-Min L2 1km NRT
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/modis/myd21.nrt.061
Description
The MODIS/Aqua Land Surface Temperature/3-Band Emissivity (LST&E) 5-Min L2 1km data product, short-name MYD21 is produced daily in five minute temporal increments of satellite acquisition. The swath is approximately 2,030 pixels along track and 1,354 pixels per line, at a nadir resolution of 1,000 meters. The MYD21 Land Surface Temperature (LST) algorithm differs from the MYD11 (doi.org/10.5067/modis/myd11_l2.061) algorithm in that the MYD21 LST algorithm is based on the ASTER Temperature/Emissivity Separation (TES) technique, whereas the MYD11 uses the split-window technique.
The Version 6.1 Level-1B (L1B) products have been improved by undergoing various calibration changes that include: changes to the response-versus-scan angle (RVS) approach that affects reflectance bands for Aqua and Terra MODIS, corrections to adjust for the optical crosstalk in Terra MODIS infrared (IR) bands, and more.
