Summary and overview

The merits, shortcomings, and future outlook of thermal IR remote sensing are appraised from a philosophical and speculative point of view in the light of the HCMM experiments. Two key questions stemming from HCMM addressed are: thermal remote sensing from space platforms now on a solid foundation in terms of demonstrated applications of real utility as well as theory, and where should NASA's research be focused in thermal remote sensing and are the potential applications sufficient to justify inclusion of thermal sensors in later generations of Earth resources satellites.
