Retrieving Aerosol Properties and Land Surface Reflectance over the Sahel from Aatsr Observations
Atmospheric aerosol properties and land surface reflectance can be retrieved from dual-angle AATSR measurements. In this paper a map of aerosol optical depth at 550 nm covering the Sahel and Southern Sahara region is presented. The map is a composite of thirtytwo 500 km wide AATSR strip-lines acquired throughout March 2003. Verification is performed using the MODIS and MISR global aerosol produ...
متن کاملCalibration Status of the Aatsr Reflectance Channels
The radiometric gains of the AATSR visible to shortwave-infrared channels are calibrated using an on-board solar diffuser. The on-board calibration is supported by vicarious techniques such as comparisons over stable desert targets to establish relative biases in the radiometric calibrations of AATSR and other optical sensors and also to determine the long-term drifts. The authors present the r...
متن کاملAatsr Land Surface Temperature Product: Comparison with Seviri and Modis in the Framework of Cefles2 Campaigns
In this paper we present a LST product obtained from Advanced Along-Track Scanning Radiometer (AATSR) data. The product has been validated with in situ measurements carried out in the framework of the CarboEurope-Flex-Sentinel-2 (CEFLES2) campaign. In addition the paper present a comparison between the proposed product and the LST retrieved from different sensors as Spinning Enhanced Visible an...
متن کاملValidation of the Aatsr Land Surface Temperature Product over Inland Waters and Vegetated Surfaces
The Land Surface Temperature (LST) product of AATSR was validated with in situ measurements at two thermally homogeneous sites: Lake Tahoe, CA/NV, USA and a large rice field close to Valencia, Spain. The AATSR LST product is based on the split-window technique using the nadir view of the 11 and 12 μm channels. The algorithm coefficients are provided for 13 different land cover classes plus one ...
متن کاملGround Measurements for the Validation of Land Surface Temperatures Derived from AATSR and MODIS Data
An experimental site was set up in a large, flat and homogeneous area of rice crops for the validation of satellite derived land surface temperature (LST). Experimental campaigns were held in the summers of 2002-04, when rice crops show full vegetation cover. LSTs were measured radiometrically along transects covering an area of 1 km. A total number of four thermal radiometers were used, which ...
