The Radiative Divergence using ARM Mobile Facility (AMF), Geostationary Earth Radiation Budget (GERB) and African Monsoon Mutidisciplinary Analysis (AMMA) Stations (RADAGAST) experiment coordinated surface and remote sensing measurements made by the U.S. Department of Energy Atmospheric Radiation Measurement (ARM) Program AMF situated in Niamey (13 degrees 29'N, 2 degrees 10'E) and by the (GERB) broadband radiometer and multi-channel spinning enhanced visible and infra-red imager (SEVIRI) on the Meteosat-8 operational geostationary satellite (stationed above 0 degrees longitude). This poster first presents the daily mean broadband solar and thermal radiative fluxes observed from the surface by the AMF and from space by GERB. The influence of temperature, water vapor, aerosols, and clouds on these fluxes is investigated. The AMF and GERB fluxes are then combined to provide estimates of the divergence of radiation across the atmosphere, and the factors that control these estimates are discussed.
This poster will be displayed at ARM Science Team Meeting.
