    NAMMA CVI CLOUD CONDENSED WATER CONTENT V1

    Metadata Updated: February 22, 2025

    In the NAMMA CVI Cloud Condensed Water Content dataset the counterflow virtual impactor (CVI) was used to measure condensed water content (liquid water or ice in particles about 8 microns in diameter and up) and Cloud Condensation Nuclei (CCN) on the DC-8 during NASA African Monsoon Multidisciplinary Analyses (NAMMA). 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. Water vapor was measured with a MayComm Tunable Diode Laser (TDL) hygrometer and non-volatile particles are examined with an optical particle counter, a condensation nuclei counter, and an impactor for subsequent chemical analyses.
