THE LANGLEY AEROSOL RESEARCH GROUP EXPERIMENT (LARGE) PROPOSES TO DELIVER HIGH-PRECISION IN SITU AEROSOL CLOUD AND METEOROLOGICAL MEASUREMENTS ABOARD THE NASA P-3B AIRCRAFT FOR THE CLOUD AND AEROSOL MONSOONAL PROCESSES-PHILIPPINES EXPERIMENT (CAMP2EX) MISSION AND TO CONDUCT POST-MISSION ANALYSES TO ADDRESS IMPORTANT AEROSOL AND CLOUD-RELATED MISSION OBJECTIVES. THE EFFORT WILL INCLUDE OPERATING A COMMON ISOKINETIC AEROSOL INLET TO SUPPLY DRIED SAMPLE AND CALIBRATION FLOW TO OTHER ONBOARD INVESTIGATORS AND PROVIDING SIGNALS TO THE AIRCRAFT DATA DISTRIBUTION AND DISPLAY SYSTEM FOR USE IN REAL-TIME FLIGHT PLANNING AND AIR MASS IDENTIFICATION. TO ENHANCE THE IMPACT AND LONG TERM BENEFIT OF THE PROJECT TO THE HOST NATION WE WILL ALSO SEEK COLLABORATIONS WITH FILIPINO SCIENTISTS IN BOTH MAKING MEASUREMENTS AND INTERPRETING DATA.
