Simulation Domain
Western-US domain: Allows analysis of ENSO cycles Grid Cells: 12-km x 12-km Decent for representing ubran vs rural influence on air quality Historical Simulation Period: 1979-2008, which has several ENSO periods; PDO variability too long to capture Boundary and Initial Conditions: NARR (~32-km resolution) Land-Use, Land-Cover Data: NLDAS2 (save Alex’s dataset for WRF VIC-RHESSys-- no need to recalibrate VIC yet!)

O FFLINE FOR CMAQ S IMULATION S EQUENTIAL R UNS
Purpose: Model nitrogen deposition and evaluate how it’s modulated by ENSO cycles Provide results to offline RHESSys and CropSyst simulations Domain & Grid Cells: A subdomain within the WRF-VIC domain Same grid cells as WRF-VIC Historical Simulation Period: A few ENSO cycles during the 1979-2008 period Chemical Boundary Conditions: 1990s from global chemical transport model MOZART? Anthropogenic Emission Inventory: 1999 or 2002 National Emissions Inventory Bioegenic Emissions: MEGANv2.1

WRF-VIC
WRF (v3.2) and VIC (v.4.0.4) has been coupled through the CESM flux coupler CPL7 Coupled WRF-VIC has been tested in a global and an Arctic domain (Chunmei Zhu, UW) For BioEarth, need to create input data spatial data for VIC for our Western US simulation & grid cells.

WRF-CMAQ
Current release, CMAQv4.7.1, is not coupled to WRF CMAQv5.0 is supposed to be released anytime now. Two-way coupling built into WRF v3.3
Only supports CAM and RRTMG shortwave radiation schemes identical on-line and off-line computational paradigms with minimal code changes flexibility in frequency of coupling Aerosol Optical Properties, Cloud Condensation Nuclei Ozone

CTIVITIES
Integrating MEGAN into Bioearth Coupling with VIC-RHESSys-CropSyst Coupling with CESM/CLM (boundary conditions) Improve soil nitrogen emissions (NO, NH3, N2O) Add particles: pollen, fungal spores, bacteria, dust Use MEGAN in BIOEARTH to identify scientific questions that can be addressed with a PNW regional field study Landcover change (e.g. poplar plantations) Interactions of biogenic emissions and anthropogenic pollution
