Participating modeling groups
GOAL: Assess the forecast skill and biases of global/ regional model simulations of SE Pacific boundary-layer clouds on diurnal and longer timescales.
WHAT? Daily hindcasts for October 2006 over the SE Pacific.
WHO? 14 modeling groups using regional and global models, including climate models run in forecast mode.
STATUS: Results near submission.
NEXT: A second phase focusing more on cloud-aerosol interaction and chemical transport based on VOCALS-REx period Oct-Nov 2008 will be announced shortly.
Most models have too low an inversion near the coast.

VOCA: Similar protocol to preVOCA using REx observations from 15 Oct -15 Nov 2008
More focus on chemical transport, aerosol concentrations and reff vs. in-situ and CALIPSO data.
We will send out a detailed protocol in summer 2009. All modeling groups are welcome (with or without chemical transport modeling capability).
