To provide accurate data the regular on-board absolute radiometric calibration of a satellite hyperspectral instrument is required. Together with the internal calibration the external calibration using comparison of radiance measurements above special ground test sites and calculated radiances is performed.

International Journal of Remote Sensing, 2014
The paper presents a newly developed radiative transfer model SDDS that simulates the reflected and emitted radiations of natural scenes with atmosphere from the visible to infrared spectrum. The software, SDDS, written in Visual Basic®, simulates the radiation transfer processes in the ‘Earth–atmosphere’ system, and calculates the interaction between ...

Classification of Surface Natural Resources based On U-NET and GF-1 Satellite Images
2020 17th International Computer Conference on Wavelet Active Media Technology and Information Processing (ICCWAMTIP), 2020Natural resources are indispensable for human survival and the protection and management of surface natural resources become more and more important. At present, remote sensing and deep learning approaches are using in land use and land cover area. In this paper, a U-Net model is developed to classify surface natural resources using GF-1 satellite ...

Provincial nature of chlorophyll and sea surface temperature observed by satellite
International Journal of Remote Sensing, 2009Monthly composite SeaWiFS derived chlorophyll, National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) derived sea surface temperature (SST) and QuikScat derived wind data of 2003-2005 (January-December) were analysed to study the provincial nature of chlorophyll-a (chl-a), SST and wind speed in the ...

An increasing number of sports fields around the world are equipped with artificial turf. This solution has been endorsed by numerous sports federations, despite concerns about the potential for injuries and higher surface temperatures. In this work we analyzed land surface temperature in 4 pairs of natural and artificial turf sports fields in Europe ...

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
In this paper, several examples of synthetic aperture radar images of the sea surface from TerraSAR-X and RADARSAT-2 in the Straits of Florida are examined with corresponding in-situ data. The in-situ observations included vertical and horizontal fine thermo-haline structure, sonar transects, current velocity, directional wave characteristics, weather ...

Abstract The northern Sinai is a sandy semi-desert. Severe overgrazing and other anthropogenic pressures contribute to an extremely sparse vegetative cover. A 6×6 km area was fenced off in the summer of 1974, constituting an exclosure from the grazing herds and from harvesting of plants for firewood. The vegetation in this exclosure recovered rapidly.
