other affiliations AERONET(Cape_San_Juan), NOAA-ESRL/CCG, NOAA-ESRL/AERO(CPR)
description This Caribbean site is within the subtropical dry forest zone, has good exposure to the easterly trades (and hence African dust), and is free of major land masses upwind, minimizing the effects of anthropogenic aerosol sources. It has an average annual precipitation of 905 mm and average temperature of 26 C. CPR was one of the sites involved in the Rain in Cumulus over the Ocean (RICO) campaign and the Puerto Rico Aerosol and Cloud Study (PRACS), which were focused on marine organic aerosols under clean maritime trade wind conditions in winter. NOAA ESRL/GMD and the University of Puerto Rico are cooperating to measure aerosol optical properties at Cape San Juan. CPR station is part of the NASA AErosol RObotic NETwork (AERONET).
