The San Diego Supercomputer Center (SDSC) and the University of California, San Diego, is providing data management, visualization and modeling resources, and expertise to a two-month wintertime field campaign to study “atmospheric rivers” and particles of dust, smoke, sea spray, and organic materials called aerosols along the western U.S. coast to better understand variability in the region’s water supply, flood and drought hazards, infrastructure requirements, and optimal reservoir operations. The latest initiative, called the CalWater 2015 project, assembled a team of federal and state agencies plus academic research institutions collaborating in a tightly-coordinated effort involving ground-based observations, air and sea-borne measurements, and advanced weather forecast models.  To read further, please visit http://www.sdsc.edu/News%20Items/PR021115_calwater.html.
