In terms of the practice of author for long time, development and situation in thermal infrared remote sensing research field were introduced in the paper. Particulary, major difficult in quantitatively investing of ground surface temperature, measurement of emissivity and its estimation in regional scale, was presented. Some problems in the quantitative application of thermal infrared remote sensing for some researchers were also pointed out. Finally, developing tendency in future and countermaeasure for recent works were discussed. The goal in the paper is “to cast brick and to attract jade" in order to promote the development in quantitative thermal infrared remote sensing.
