2. CalWater2 planning workshop, 5-7 Nov, 204, La Jolla 2 Airborne Expendable BathyThermograph (AXBT) Plan Science Objectives: Deploy Airborne eXpendable Bathy Thermographs (AXBTs) during the CalWater2 field campaign from the NOAA P-3 Using COAMPS moist adjoint model as possible guidance Together with the planned NOAA dropsondes deployment, the combination of AXBT-dropsonde observations will provide co-located atmospheric and ocean temperature profiles that can be used to study the air-sea fluxes exchange and its influence to the evolution of the Atmospheric River (AR) events Equipment: 4 Pallets, total of 196 AXBTs Weight: ~15-19lb per AXBT Size: ~4x4x4 cubic feet (per pallet) Require shipment to and storage at the P-3 operation site Data: 1-m vertical resolution, use NOAA AXBT real-time automated receiving system possible real-time data feed to NAVO NCODA via ftp Sampling strategy Survey the upper-ocean environment before, during, and after an AR event
