The NOAA AERosols and Oceans Science Expeditions (AEROSE) is a series of intensive field experiments conducted aboard the U.S. A part of the NOAA PIRATA Notheast Extension (PNE) mission, the AEROSE campaigns have grown to become one of the most extensive collections of in situ measurements of the Saharan air layer (SAL) and associated African dust and smoke outflows over the tropical Atlantic Ocean. The AEROSE shipboard data complement to date includes Vaisala rawinsonde observations (RAOBs), calibrated IR spectra and high accuracy sea surface skin temperature (skin SST) from Marine Atmospheric Emitted Radiance Interferometers (M-AERI) , Microtops sunphotometers, ozonesondes, micropulse lidar (MPL), ceilometers, Multi-Filter Rotating Shadowband Radiometers (MFRSR), surface radiative fluxes, among many, many others. Thus far, 7 trans-Atlantic campaigns have taken place during spring and summer and an eighth campaign is scheduled to take place in September 2012.
