Abstract

The objective of the Infrared Laboratory-LIR has been the design and development of simple and low-cost IR systems for the resolution of specific problems in real time. The study of clouds in the IR region is a problem studied since the first on-board measurement systems. Nowadays imaging systems are multispectral instruments that provide accurate information on clouds. These systems are generally large in size, weight and cost. However, in many situations, the goal is simply to get auxiliary information about the clouds. Then, the low-cost approach of LIR is ideal for designing simple cloud characterization systems. In this work, a methodology is presented to determine the emissivity and temperature of the clouds based on the brightness temperature measured from space by a bi-spectral camera in the 10 and 12 microns bands. In addition, we provide quantitative information on the capabilities of the methodology based on real data provided by MODIS instrument.
