The scientific results of the VOCALS field campaign are based on analysis of observations made by instruments located on ships, aircraft, and land. This map shows the paths followed by ships and planes over the Southeast Pacific and the observation stations along the coasts of Chile and Peru.

What are the results of VOCALS?
Long after the VOCALS campaign is completed, the scientistsí work will continue. They must process, review, and study the data to determine what has been learned. Many model runs will be made and analyzed. Eventually, they will publish their discoveries in scientific journals and give oral presentations at conferences.
VOCALS will allow an unprecedented examination over an entire month of how variability in ocean currents, ocean upwelling, marine winds, and air pollution will impact the chemical and physical properties of the lower atmosphere, the clouds, and the amount of precipitation found there. The climate characteristics of the SEP are further complicated by the close proximity of the Andes Mountain range which forms a barrier to westerly winds and the transport of moisture.
It is expected that measurements obtained by VOCALS will have a broad impact upon current knowledge in the fields of atmospheric science and oceanography. The data generated in the field will stimulate the development of a broad range of numerical process models exploring the atmosphere. They could also help to accelerate the improvement of regional and global climate. VOCALS could ultimately lead to much better predictions of future climate. Climate prediction is increasingly important to communities around the world that are vulnerable to the impacts of climate change, such as sea level rise, heat waves, less reliable precipitation, and changes in growing seasons.
