Operational Derivation of Surface Albedo and Down-welling Short-wave Radiation in the Satellite Application Facility for Land Surface Analysis
نویسندگان
چکیده
The Satellite Application Facility for Land Surface Analysis hosted by the Portuguese Meteorological Institute in Lisbon generates and distributes value added satellite products for numerical weather prediction and environmental applications in near-real time. Within the project consortium Météo-France is responsible for the land surface albedo and down-welling short-wave radiation flux products. Since the beginning of the year 2005 Meteosat Second Generation data are routinely processed by the Land-SAF operational system. In general the validation studies carried out so far show a good consistency with in-situ observations or equivalent products derived from other satellites. After one year of operations a summary of the product characteristics and performances is given.

Operational near Real-time Derivation of Land Surface Albedo and Down-welling Short-wave Radiation from Msg Observations
In the framework of the EUMETSAT Satellite Application Facility for Land Surface Analysis (Land-SAF) we develop surface albedo and short-wave radiation products which will be generated in near real-time from observations provided by the MSG/SEVIRI instrument. The albedo algorithm exploits the diurnal variation of the illumination angle, which provides information on the angular variation of ref...
متن کاملValidation of Msg Derived Surface Incoming Global Short-wave Radiation Products over Belgium
Appropriate information on solar resources is very important for a variety of technological areas, such as: agriculture, meteorology, forestry engineering, water resources and in particular in the designing, sizing and monitoring of solar energy systems. Solar radiation is observed by means of networks of meteorological stations. However, the availability of observed solar radiation measurement...
متن کاملRadiation balance and urban land use (case study: Kermanshah city)
Population growth and urbanization development are the main triggering factors of changes in urban land uses. These, in turn, result in changes in the components of radiation balance. The present study tries to analyze the role of urban land uses in radiation balance by calculating net radiation and its analysis. For this purpose, the Landsat 8 satellite image of 2016 was used. Characteristics ...

Soil is one of the most important natural resources of any country. the erosion causes not only the depletion of the soil and the loss of the land, causing great and irreparable damages, but also with the deposition of materials in streams, reservoirs, ports, and reduced pool capacity. Therefore, it should not be underestimated. In this study, we identify and zoning of the erosion areas in the ...

Glaciers influenced by climatic factors and therefore as an important indicator in the study of climate change are studied. Although morphometric analyzes of glaciers based on the analysis of optical satellite data can provide an opportunity to measure ice outcrops, but the identification and determination of the buried glaciers underneath the glacial debris and, consequently, the determination...
