Investigation of High Resolution Water Vapor and Aerosol

Investigation of High Resolution Water Vapor and Aerosol Distributions in Tropical Cyclone Development During the NAMMA Field Experiment LASE Measurements • Water vapor profiles - daytime and nighttime - surface to tropopause - 330 m vert. & 15 km hor. - accuracy (6% or 0. 01 g/kg) • Aerosol/cloud profiles -30 m vert. & 200 m hor.

Krishnamurti, FSU (Co-I); Jason Dunion, NOAA/U Miami (Co-I) LASE Retrievals • Relative humidity profiles • Aerosol backscatter/extinction profiles • Precipitable Water Vapor • qe , qv Recent Field Experiments: CAMEX-3 & 4, IHOP References: Kamineni et al. , GRL (2003); Kamineni et al. , JAS (2006); Wakimoto et al. , MWR (2006) • • • NAMMA Investigations Link GOES SAL imagery w LASE mea. & interaction w AEWs/TCs Invest. SAL properties w simul. air, space, & gnd measurements Sample various SAL regions (e. g. , leading edge and dust/SAL source) Study impact of synoptic-scale SAL & moisture fields on forecasting AEW, TC, & hurricane development Sample AEWs/TCs on consecutive days to examine impact of SAL and humidity fields on their development Evaluate ability of satellite meas. to represent SAL moisture, aerosols, clouds (e. g. AIRS, CALIPSO)
