Analysing the advantages of high temporal resolution geostationary MSG SEVIRI data compared to Polar Operational Environmental Satellite data for land surface monitoring in Africa

چکیده
Since 1972, satellite remote sensing of the environment has been dominated by polar-orbiting sensors providing useful data for monitoring the earth’s natural resources. However their observation and monitoring capacity are inhibited by daily to monthly looks for any given ground surface which often is obscured by frequent and persistent cloud cover creating large gaps in time series measurements. The launch of the Meteosat Second Generation (MSG) satellite into geostationary orbit has opened new opportunities for land surface monitoring.

Daily estimates of the tropospheric aerosol optical thickness over land surface from MSG geostationary observations
The paper presents an innovative method to derive aerosol optical thickness (AOT) on a continental scale, using MSG observation. The approach consists in taking into account the high temporal resolution of the observing system, in order to discriminate between surface and aerosol effects. A suitably extended semi-empirical BRDF model is applied, combined with a recursive scheme. The method is n...
متن کاملDetermining diurnal variations of land surface emissivity from geostationary satellites
[1] Infrared (IR) land surface emissivity (LSE) with a high temporal and spatial resolution is very important for deriving other products using IR radiance measurements as well as assimilating IR radiances in numerical weather prediction (NWP) models over land. Retrieved from various satellite instruments, many LSE databases are available for operational and research use. Most are updated only ...
متن کاملAn Angular and Emissivity Dependent Algorithm to Determine Sea Surface Temperature from Msg-seviri Data
A frequent and high-accuracy determination of Sea Surface Temperature (SST) would permit an improvement in the forecasting of natural hazards and the monitoring of the effects of climate change. The Spinning Enhanced Visible and Infrared Imager (SEVIRI) on board the geostationary METEOSAT Second Generation (MSG) platforms offers this possibility. Algorithms for SST retrieval from MSGSEVIRI data...
متن کاملSynergetic exploitation of meteorological geostationary payloads "SEVIRI" and "JAMI" for quantitative, real-time, global volcano monitoring
The eruptive unrests of active volcanoes are always associated to the emission of molten rocks at temperatures between 900-1500K, and to power releases typically above 10 Watts. Such high-temperature, surface volcanic features present overall moderate size, spanning in width between a few tens of meters (small active lava flows) and several hundred meters (large active lava flows, molten lava l...
متن کاملDetermination of Tropical Radiation Budget at High Time and Space Resolution by Combination of Geostationary and Polar Satellite Measurements
ERB(Earth Radiation Budget) data describe how the earth gains en-gergy, due to absorbed solar radiation ux, or looses energy, due to emitted thermal radiation ux. Since the atmospheric energetics is described by diierential equations with derivatives in space and in time, high resolution spatial and temporal ERB data should be available. ERB data derived from satellite measurements exist (ERBE(...
