1. Land surface model: VIC UW: Bart Nijssen, Amanda Tan, Dennis P. Lettenmaier DRC: Jose Renteria, Kevin Lindt NPS: Andrew Roberts Consultant: Tony Craig RASM Project Meeting: May 15-17, 2012, Monterey, CA

2. Personnel changes Left: – Chunmei Zhu (postdoc) New: – Bart Nijssen (research scientist) Unchanged: – Amanda Tan (graduate student) – Dennis Lettenmaier (PI)

3. VIC infrastructure developments Parallelization: – Allows VIC to run on multiple processors – Allows VIC to run alongside the ocean model – Significantly reduces model runtime Standardized output and state files (NetCDF) In-progress: multiple output streams

4. Model simulations Offline simulations – Long-term simulations (from 1948-) – Interpolated to RASM grid – Based on Sheffield et al. 2006 Sheffield, J., G. Goteti, and E. F. Wood (2006), Development of a 50-year high-resolution global dataset of meteorological forcings for land surface modeling, J Climate, 19(13), 3088-3111, doi:10.1175/jcli3790.1.
