Night-time thermal infrared (NTIR) data provides an additional and potentially valuable source of information for mineral explorers. This technology is used for locating palaeocoastal heavy mineral sands and palaeochannels for uranium and placer deposits. To date, the most frequently used thermal imagery is derived from the National Oceanic and Atmospheric Administration (NOAA) Advanced Very Hi...

[1] We establish the potential of TERRA-1 Moderate Resolution Imaging Spectrometer (MODIS) data for discriminating and mapping tropical secondary forest regeneration stages in the Brazilian Legal Amazon, in terms of both their age and pathway. In using MODIS data, many difficulties encountered in local to regional scale mapping and discrimination of regeneration stage using NOAA Advanced Very H...

Abstract. We analysed the operational infrared (IR) calibration of the AVHRR radiometers onboard NOAA-12, 14 and 15 satellites. It was shown that solar blackbody contamination aVects the calibration of all IR channels. This source of error in the calibration may result in uncertainties in the estimation of sea surface temperature (SST) up to 0.5K or more. We propose an approach to correct this ...

We propose a simple scheme to estimate surface evaporation over large heterogeneous areas using remote sensing observations. Our approach is based on a relationship between easily measured surface parameters (e.g. radiometric surface temperature) and a surrogate for effective surface resistance. Preliminary results, using remotely sensed data sets from AVHRR NOAA-14 over the Southern Great Plai...
