THE OVERALL GOAL OF THIS PROJECT IS TO IMPROVE THE UNDERSTANDING OF THE RELATIONSHIP BETWEEN CLOUD DROPLETS AND TURBULENCE. SPECIFICALLY HOW TURBULENCE INFLUENCES THE SMALL-SCALE (MM TO CM) ORIENTATION OF DROPLETS WILL BE ANALYZED USING DATA COLLECTED FROM THE PERUVIAN AND NAMIBIAN STRATOCUMULUS (SC) DECKS. THESE TWO REGIONS ARE OF PARTICULAR INTEREST DUE TO THE LARGE EFFECT THAT SC DECKS HAVE ON EARTHS RADIATIVE BUDGET. THE STATISTICAL STATIONARITY OF THE SC CLOUD DROPLETS ALSO OFFER AN IDEAL ENVIRONMENT FOR STUDYING THE DEVIATIONS IN PERFECT RANDOMNESS OF SAID DROPLET ENVIRONMENT. DATA WAS COLLECTED DURING THE OCEAN-CLOUD-ATMOSPHERE-LAND STUDY REGIONAL EXPERIMENT (VOCALS-REX) AND THE OBSERVATIONS OF AEROSOLS ABOVE CLOUDS AND THEIR INTERACTIONS (ORACLES) NASA EV2 CAMPAIGNS FOR THE PERUVIAN AND NAMIBIAN REGIONS RESPECTIVELY. CLOUD DROPLET ARRIVAL TIMES (AT A SPATIAL RESOLUTION OF 10-4 M) WERE MEASURED USING THE PHASE-DOPPLER INTERFEROMETER (PDI) FLOWN DURING BOTH CAMPAIGNS. THE OBJECTIVES OF THIS WORK INCLUDE: (1) CALCULATE DROPLET CLUSTERING AS A FUNCTION OF IN-CLOUD HEIGHT AND AS A FUNCTION OF AEROSOL NUMBER CONCENTRATION (ANC). (2) COMPARE DROPLET CLUSTERING BETWEEN PRECIPITATING AND NON-PRECIPITATING REGIONS OF SC CLOUDS. (3) MEASURE HOW DROPLET CLUSTERING CHANGES AS A FUNCTION OF DROPLET SIZE FOR NON-PRECIPITATING CLOUD SECTIONS. DROPLET CLUSTERING WILL BE MEASURED USING THE PAIR-CORRELATION FUNCTION (PCF). TURBULENT MEASUREMENTS OF THE VIRTUAL KINEMATIC HEAT FLUX AND THE STRAIN RATE TENSOR WILL ALSO BE CALCULATED FOR EACH OF THE OBJECTIVES LISTED ABOVE. A BETTER UNDERSTANDING OF THE RELATIONSHIP BETWEEN TURBULENCE AND DROPLET CLUSTERING CAN LEAD TO MORE PROFICIENT MICROPHYSICAL PARAMETERIZATIONS IN PRECIPITATION MODELING (SPECIFICALLY THAT OF COLLISIONCOALESCENCE) LEADING TO AN OVERALL BETTER MACROSCOPIC REPRESENTATION OF CLOUDS SUCH AS CLOUD LIFETIME AND SIZE IN RADIATION MODELING. THIS IS GREATLY NEEDED CONSIDERING CLOUDS REMAIN ONE OF THE GREATEST SOURCES OF UNCERTAINTY IN ESTIMATING CLIMATE SENSITIVITY
