The VAMOS1 Ocean-Cloud-Atmosphere-Land Study Regional
Experiment (VOCALS-REx) was an international field program designed to make
observations of poorly understood but critical components of the coupled
climate system of the southeast Pacific. This region is characterized by
strong coastal upwelling, the coolest SSTs in the tropical belt, and is home
to the largest subtropical stratocumulus deck on Earth. The field intensive
phase of VOCALS-REx took place during October and November 2008 and
constitutes a critical part of a broader CLIVAR program (VOCALS) designed to
develop and promote scientific activities leading to improved understanding,
model simulations, and predictions of the southeastern Pacific (SEP) coupled
ocean-atmosphere-land system, on diurnal to interannual timescales. The other
major components of VOCALS are a modeling program with a model hierarchy
ranging from the local to global scales, and a suite of extended observations
from regular research cruises, instrumented moorings, and satellites. The two
central themes of VOCALS-REx focus upon (a) links between aerosols, clouds
and precipitation and their impacts on marine stratocumulus radiative
properties, and (b) physical and chemical couplings between the upper ocean
and the lower atmosphere, including the role that mesoscale ocean eddies
play. A set of hypotheses designed to be tested with the combined field,
monitoring and modeling work in VOCALS is presented here. A further goal of
VOCALS-REx is to provide datasets for the evaluation and improvement of
large-scale numerical models. VOCALS-REx involved five research aircraft, two
ships and two surface sites in northern Chile. We describe the instrument
payloads and key mission strategies for these platforms and give a summary of
the missions conducted.
