Abstract:
The NASA African Monsoon Multidisciplinary Analyses (NAMMA) campaign is 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. NASA will also made extensive use of its orbiting satellites (including Aqua, TRMM, and the recently-launched Cloudsat/CALIPSO) and modeling capabilities to improve its forecasts and flight plans.
The NAMMA Senegal Rain Gauge Network consisted of 40 rain gauge sites (AMMA 1-40) located in various places throughout Senegal, West Africa. The Rain Gauge Network consisted of the large-scale rain gauge network, 2 gauges co-located at NPOL to provide coincident measurements with each other and Larry Bliven's Rain Imaging System (RIS) and the dense-scale rain gauge network. The rain gauges collected one-minute accumulation data. The location and photos of each site can be found in an accompanying PDF document NAMMA_Raingauge_network.pdf.
