We report the results of a modeling study on the sensitivity of normalized difference vegetation index (NDVI) and surface reflectance to differences in instrument spectral response functions (SRF) for various Advanced Very High Resolution Radiometers (AVHRR) onboard the National Oceanic and Atmospheric Administration’s (NOAA) satellites NOAA-6–16 as well as the Moderate Resolution Imaging Spect...

A number of Earth remote sensing satellites are currently carrying passive microwave radiometers. A variety of different retrieval algorithms are used to estimate surface rain rates over the ocean from the microwave radiances observed by the radiometers. This study compares several different satellite algorithms with each other and with independent data from rain gauges on ocean buoys. The rain...

The next generation of remote sensing observing systems will routinely provide multispectral data from a very large number of sensors. For example, the Landsat-type instrument of the planned Earth observing system (Eos) satellite will be the HIghResolution Imaging Spectrometer (HIRIS). The HIRIS will have 192 channels, compared to seven on the current Landsat Thematic Mapper (TM). Similarly, th...

Snow cover area is one of the most important criteria to calculate snow melt runoff. This can have an effect on the biology of the plant and the environment of a region. Using the catchment basin physical characteristic to calculate snow cover area is a conventional method, though its accuracy is not good enough. Most of the useful methods in calculating snow cover area are based on satellite i...

This paper presents the foundations of a decision support system for the localisation of fisheries based on AI techniques. The purpose of such a system is to reduce the costs of fishing fleets without endangering the sustainable development of the natural resources. Our data sources are satellite images (OrbView-2, Series NOAA, Topex/Poseidon), as well as real catch data obtained from the fishi...

Total precipitable water (TPW), the amount of water vapor in a column from the surface of the earth to space, is used by forecasters to predict heavy precipitation. In this paper, a process for blending TPW values retrieved from two satellite sources is detailed: the Advanced Microwave Sounding Unit (AMSU) instruments on three NOAA satellites, and the Special Sensor Microwave Imager (SSM/I) ins...
