In order to improve knowledge of the Saharan heat low dynamics, the Transportable Remote Sensing Station (TReSS) was deployed in Tamanrasset from February to September 2006 under the auspicies of the Office National de la Météorologie Algérienne, Direction Météorologie Région Sud, during the African Monsoon Multidisciplinary Analysis (AMMA) Special Observing Period. TReSS is an autonomous and high-performance system designed to observe radiative and structural properties of clouds and aerosol layers, as well as atmospheric boudary layer (ABL) dynamics. The meteorological station of Tamarasset located in the SHL region and is equipped for monitoring the radiative budget at the surface and microphysical properties of desert dust (at the surface). In addition to being complementary, the Office National de la Météorologie Algérienne and the TReSS measurements are relevant for assessing the diurnal and seasonal evolution of the SHL main characteristics.
This presentation provides an overview of the survey conducted during the WAM onset period of the evolution of key SHL features measured at the Tamanrasset “Supersite”. Comparisons with selected level 1 and level 2 Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (equipped with the nadir pointing backscatter lidar CALIOP) products over the Sahara, will also be discussed.
