AB: The NOAA Earth System Research Laboratory (ESRL) air-sea interaction group has initiated a planned multi-year study of climate processes in the E. Equatorial Atlantic that follows a (now ended) 5-year study in the E. Equatorial Pacific. The goal is to collect observations over several years to characterize the balance of turbulent and radiative fluxes at the surface and the role of clouds and precipitating systems in variations of that balance. The observations will also provide a venue to statistically examine model physics and satellite retrievals. The project was inaugurated in the summer of 2006 as part of a joint ESRL, University of Miami, and NOAA/AOML study during the Special Observing Period (SOP1) of the African Monsoon Multidisciplinary Analyses project (AMMA). The air-sea interaction group at ESRL contributed to the field campaign by measuring traditional near-surface meteorological data aboard the R/V Ronald H. Brown in the northeast tropical Atlantic during May 27- July 16. The observations included direct turbulent fluxes, radiative fluxes, cloud properties, aerosols, and atmospheric boundary layer profiles. This presentation will focus on flux comparisons using the direct covariance and inertial- dissipation methods, and the NOAA TOGA-COARE bulk flux algorithm (version 3.0), connecting clear-sky radiative fluxes with near-surface aerosol concentrations, and comparisons of cloud radiative forcing characteristics to those obtained previously in the Pacific study.
