NAMMA LANGLEY AEROSOL RESEARCH GROUP EXPERIMENT (LARGE) V1

Published by NASA/MSFC/GHRC | National Aeronautics and Space Administration | Catalog Last Checked: June 23, 2026 at 08:37 PM | Dataset Last Updated: June 23, 2026
The NAMMA Langley Aerosol Research Group Experiment (LARGE) dataset contains data collected from the following in situ aerosol sensors: condensation nuclei counters, optical particle spectrometers, an aerodynamic particle sizer, and integrating nephelometers. These instruments measure aerosol number density, aerosol size distribution, total scattering and backscattering coefficients. These data files were generated during support of the NASA African Monsoon Multidisciplinary Analyses (NAMMA) campaign, a field research investigation sponsored by the Science Mission Directorate of the National Aeronautics and Space Administration (NASA). This mission was based in the Cape Verde Islands, 350 miles off the coast of Senegal in west Africa. Commencing in August 2006, NASA scientists employed surface observation networks and aircraft to characterize the evolution and structure of African Easterly Waves (AEWs) and Mesoscale Convective Systems over continental western Africa, and their associated impacts on regional water and energy budgets.
