    • NAMMA SECOND GENERATION AIRBORNE PRECIPITATION RADAR (APR-2) V1

    Metadata Updated: September 19, 2025

    The NAMMA Second Generation Airborne Precipitation Radar (APR-2) dataset was collected by using the Second Generation Airborne Precipitation Radar (APR-2), which is a dual-frequency (14 GHz and 35 GHz), Doppler, dual-polarization radar system that includes digital, real-time pulse compression, extremely compact RF electronics, and a large deployable dual-frequency cylindrical parabolic antenna subsystem. This system measures radar reflectivity and doppler velocity at both the Ku- and Ka-band. 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.
