The Pacific Climate Workshop (PACLIM) is a multidisciplinary workshop that broadly addresses the climatic phenomena occurring in the eastern Pacific Ocean and western North America. The purpose of the workshop is to understand climate effects in this region by bringing together specialists from diverse fields including physical, social, and biological sciences. Time scales from to the millennial-scale Pleistocene variability to current temperature and precipitation records are addressed in oral and poster presentations.

The theme of the 2015 PACLIM workshop addresses the issue of drought: How we develop long term records of drought, how we monitor drought and how we predict drought. The remainder of the meeting is devoted to a wide range of climate-related topics.

The atmosphere of the workshop is intentionally informal, and room and board are provided for many of the participants. This year, the workshop was organized by faculty from Sonoma State University, and the University of Nevada, Reno with support from representatives of; the U.S. Geological Survey. The funding and other sources of support come from several agencies:

  • The Desert Research Institute: Alan Gertler
  • The US Geological Survey, Climate and Land Use Change Research Development Program: Debra Willard
  • The University of Nevada, Reno: Frank Fanelli and Daniel Fergus, Teaching Learning Technologies
