A simple technique for estimating surface temperature by means of a thermal infrared radiometer
1992
Abstract In this Letter we present a simple technique for estimating surface temperatures from data obtained by means of a thermal infrared radiometer. The technique is based simply on the use of a table and a graph, from which cmissivity and atmospheric effects are easily evaluated. The accuracy is better than a tenth of a degree when emissivity and atmospheric radiance arc known.
A mathematical study on effective wavenumber, an operative computation procedure, and its use with radiance-temperature relationships
2003
In this paper we study the existence of effective wavenumber for any sensor by means of simple mathematics. We implement a numeric algorithm, based on the developed mathematical background, into a computer program named 'srf2radi', which is freely available via anonymous File Transfer Protocol (FTP) at ftp://ftp.uv.es/pub/src/. The number of effective wavenumbers for each temperature and their accuracy are also computed and studied for NOAA-16 Advanced Very High Resolution Radiometer Version 3 (AVHRR/3) channel 4. These effective wavenumbers can be used to obtain radiance-temperature relationships with physical meaning for any sensor in user-defined temperature intervals.
