Here we offer daily composites and monthly means of the land surface temperature as derived from infrared radiances measured with the Terra or Aqua MODIS sensors at its channels 31 and 32. From radiances obtained under clear-sky conditions the land surface temperature is obtained using a split window technique. This data set is the final product of a product chain. In this chain, the land surface temperature is calculated for each day first for single MODIS overpasses, then for tiles with 1000 m resolution (products MOD11A1 and MYD11A1) and finally for the climate modeling grid (CMG) with 0.05° grid resolution. These daily data are further processed in order to receive 8-day composites or even a monthly mean.
To produce this data set other parameters (actually all MODIS products) are required, that is the MODIS vertical temperature and water vapor profiles, the MODIS cloud mask, the land cover distribution, and the snow cover.
The data offered here are based on Terra or Aqua MODIS data of MODIS Collection 061.

The data offered here are part of the well-validated new Collection 061 (also C6.1) of the MODIS product suite. Collection 061 includes substantial radiometric calibration improvements which ensures a consistent time series (see e.g. Lyapustin et al., 2014 in references). The accuracy of the retrieved land surface temperature is given in the data set in form of a quality flag (see parameters). Generally, only those grid cells contain a valid value where a proper land surface temperature retrieval was possible. Gaps in the data are almost solely based upon a persistent cloud cover. Compared to Collection 6.0 a number of cross-talk issues has been eliminated in Collection 6.1; also sensor drift has been taken into account in an improved manner.
The original data set includes a couple of more parameters such as the observation time, observation angle, number of days with clear-sky conditions during the month under consideration as well as emissivities of channels 20, 22, 23, 29, 31, and 32. All this information is not included in the data set offered here, however, in order to keep it simple and the data volume low.
New results indicate that there might be a cold bias (clear sky bias) of MODIS LST over winter-time snow covered areas.
