COUPLED WRF-VIC SIMULATION FOR
SEQUENTIAL RUNS
Simulation Domain
Decisions Made! 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!)

OFFLINE CMAQ SIMULATION
FOR SEQUENTIAL RUNS 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

STATUS OF COUPLED 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.

STATUS OF COUPLED 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

COUPLED WRF-CMAQ TEST CASE
From Wong et al., CMAS 2011 Presentation
Widespread wildfires resulted in high aerosol loading during mid/late June 2008 in California
Aerosol-radiation feedbacks resulted in reduced shortwave radaition reaching the surface

STATUS OF MEGANRECENT IMPROVEMENTS (VERSION
2.1)
U.S. landcover
high resolution (30-m) PFT (CLM scheme) and species composition for crops, trees, shrubs, grass. Integrates CDL, NLCD, FIA, NRCS data with adjusted NLCD in urban areas.
LAI data: MODIS 8-day for individual years
Biogenic VOC
Updated emission factors, emission activity parameters
Response to increasing CO2
Additional compounds
Soil emissions
Biogenic VOC: soil moisture, litterfall, temperature
Nitric oxide: soil moisture, temperature and fertilizer
Crops
Urban

STATUS OF MEGANONGOING/PLANNED ACTIVITIES
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
