Abstract
Spectral radiance of various background elements (e.g., vegetation, rocks, snow and concrete) were measured in the 4.5 - 5 micrometers atmospheric window, both during the day and night. Effective temperatures of these surfaces were calculated and an attempt was made to evaluate true temperatures as well. The results are quite satisfactory, probably due to the following reasons: (1) The emissivity of most natural surfaces in this spectral region is high. Therefore the non-thermal (reflected solar component of the radiance) is small. (2) The spectral variation of the emissivity of most natural surfaces in this spectral region is very small, thus facilitating the evaluation of contact surface temperature. The results suggest the feasibility of using the 4.5 - 5 micrometers atmospheric window for background temperature evaluation.
