February 24, 2009

By Andrew R. Korb, Peter Dybwad, Winthrop Wadsworth, and John W. Salisbury ABSTRACT A hand-held, battery-powered Fourier transform infrared spectroradiometer weighing 12.5 kg has been developed for the field measurement of spectral radiance from the Earth’s surface and atmosphere in the 3–5-µm and 8–14-µm atmospheric windows, with a 6-cm21 spectral resolution. Other versions of this [...]

Global Infrared Land Surface Emissivity:

February 12, 2009

UW-Madison Baseline Fit Emissivity Database From the University of Wisconsin CIMSS data section: http://cimss.ssec.wisc.edu/iremis/ This global database of infrared land surface emissivity is derived using input from the Moderate Resolution Imaging Spectroradiometer (MODIS) operational land surface emissivity product (MOD11). The baseline fit method (Seemann et al., 2007), based on a conceptual model developed from laboratory [...]

ET10 Reflectometer Measures Emissivity

March 21, 2008

San Diego CA, USA –Surface Optics’ ET10 measures emissivity values in two most commonly used spectral regions, 3 to 5 and 8 to 12 microns. Its main application is to produce emissivity values for the infrared cameras. Advanced IR cameras require the input of an emissivity value for accurate temperature calculations. The emissivity values obtained [...]
