Presentation Transcript

  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 • Coupled simulations • r28RB1g • r30RB1g • Analysis period: 1990-1999 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.
