Land Surface Temperature/Emissivity (MOD11)
Since NASA currenlty has two Land Surface Temperature (LST) and Emissivity products from the MODIS sensor, we have prepared this report to help users determine the best product for their needs.
The MOD11 product is the heritage LST product and the MOD21 product is the new LST product generated beginning with the distribution of Collection 6. The two products emanate from two different methodologies and thus are two separate products.
The MOD11 Land Surface Temperature (LST) and Emissivity daily data are retrieved at 1 km pixels by the generalized split-window algorithm and at 6 km grids with the day/night algorithm. In the split-window algorithm, emissivities in bands 31 and 32 are estimated from land cover type, atmospheric column water vapor, and the lower boundary air surface temperature is separated into tractable sub-ranges for optimal retrieval. In the day/night algorithm, daytime and nighttime LSTs and surface emissivities are retrieved from pairs of day and night MODIS observations in seven thermal infrared (TIR) bands. The product is comprised of LST, emissivity, quality indicators, observation parameters.
