INTERCALIBRATION OF METHODS FOR THE LAND SURFACE THERMODYNAMIC TEMPERATURE RETRIEVING INSIDE URBAN AREA BY THERMAL!INFRARED SATELLITE IMAGING
A comparative independent evaluation (intercalibration) of two methods for the land surface thermodynamic temperature retrieving by thermal infrared satellite imaging of Kiev was done in the framework of joint Russian and Ukrainian project “Investigation of urbanization influence on city’s microclimate (using thermal infrared satellite mapping)”, supported by RFBR (No 14-05-90416) and NAS of Ukraine (No 10-05-14). Both, low resolution EOS/MODIS and medium!resolution Landsat 8/TIRS thermal infrared images were processed. Algorithms for the thermodynamic temperature and emissivity retrieving based on regressions and ground!truth measurements were applied and compared. Average regular error of land surface temperature retrieving was estimated as –0.93°C. Such accuracy is quite acceptable for the urban environment quantitative temperature monitoring by thermal infrared satellite imaging.
