  1. CALWATER2 Field Study of Air-Sea Interaction and AR dynamics in Midlatitude Pacific Storms • Ship (NOAA Brown) • Ship Field Duration – 30 days • Time Window – Jan 1, 2015 – Mar 10, 2015 • Ship location – Nominally 35-40 N 130 W • Aerosols, meteorology, clouds, precip, waves, surface fluxes

  2. Science Targets Ship Ops • Characterization of near surface meteorology, aerosols, fluxes • Profiles T/RH/U • Cloud properties, Precip structures • Surface budgets: • Moisture (evap and precip) • Aerosols (production, deposition) • Wave spectra and breaking, bubbles
