Title
Measuring Of Thermal Radiation Multi-Reflection Information In Soil-Vegetation System
Abstract
First of all the paper discussed the action of objects' thermodynamic characteristics, environmental factors, microclimatological parameters, soil physical parameters, ecological parameters, especially sensible and latent heat exchange on thermal radiation exchange. Particularly, increase or decrease of the objects' temperature was mentioned when measuring thermal infrared multi-reflection in a non-isothermal system. Reflection radiation and emission radiation should be separated when extracting multi-reflection radiation information from measured signals of the thermal radiometer. And the applicability of Kirchhoff's law in a non-isothermal system should also be considered. On the base of above, an instrument for measuring thermal infrared multi-reflection was developed and a kind of algorithm was put forward for extracting reflection radiation from mixed thermal radiation information. We did field experiments for measuring thermal infrared multi-reflection in 2004. Experiments and results showed that measurement accuracy of twice-thermal reflection radiation in soil-vegetation system could meet the needs of the most models at present.
