Recovering Surface Temperature and Emissivity from Thermal Infrared Multispectral Data
In 1992 Thermal Infrared Multispectral Scanner (TIMS) ferent lines on the same day. However, there are differdata were acquired from the NASA C-130 aircraft over ences when the same area is seen on the two days espethe Sahelian region of West Africa as part of the Hydrocially for the low emissivity values. Some of these logical and Atmospheric Pilot Experiment in the Sahel differences may be du...
متن کاملTemperature / Emissivity Separation Algorithm Theoretical Basis Document
The ASTER scanner on NASA's Terra (EOS-AM1) satellite will collect five channels of TIR data with an NE∆T of ≤0.3K to estimate surface kinetic temperatures and emissivity spectra, especially over land, where emissivities are not known in advance. Temperature/emissivity separation (TES) is difficult because there are five measurements but six unknowns. Various approaches have been used to constr...
متن کاملAn optimization algorithm for separating land surface temperature and emissivity from multispectral thermal infrared imagery
Land surface temperature (LST) and emissivity are important components of land surface modeling and applications. The only practical means of obtaining LST at spatial and temporal resolutions appropriate for most modeling applications is through remote sensing. While the popular split-window method has been widely used to estimate LST, it requires known emissivity values. Multispectral thermal ...
متن کاملA Simplified Method for Measuring Land Surface Temperature and Emissivity Using Thermal Infrared Split-window Channels
Satellite land surface temperature (LST) derivation is usually performed at infrared spectrum using multi-channel technique. Because of coupled effects in LST problem, spectral land surface emissivity information is required explicitly or implicitly in such technique, which itself is difficult to be determined accurately. Gillespie et al. [1] presented a numerical method for separating LST and ...
متن کاملErrors analysis on temperature and emissivity determination from hyperspectral thermal infrared data.
Sensitivity analysis of temperature-emissivity separation method commonly applied to hyperspectral data to various sources of errors is performed in this paper. In terms of resulting errors in the process of retrieving surface temperature, results show that: (1) Satisfactory results can be obtained for heterogeneous land surfaces and retrieval error of surface temperature is small enough to be ...
