What we ll be running
What We’ll Be Running:

The Weather Research and Forecasting model

with Chemistry (WRF-Chem) Version 3.4

(Release Date: April 2012)

Fully coupled, “online”, state-of-the-art

weather/chemistry model


Horizontal domains
Horizontal Domains:

(tentatively)

45 km

15 km


Vertical domains
Vertical Domains:

  • ~70 terrain-following sigma levels

  • Packed in the boundary layer and near the tropopause

  • Model top of 10 hPa

TTL

~1 km


Met initial and boundary conditions
Met Initial and Boundary Conditions

  • Global Forecast System (GFS) 0.5°x0.5° real-time data

  • 3 hourly time intervals


Chem Initial and Boundary Conditions

  • MOZART-4

    • CO is assimilated with MOPITT CO retrievals

    • Also uses GFS meteorology

  • RACM chemical mechanism

  • MEGAN biogenics

  • Biomass burning emissions from MODIS

  • Anthropogenic emissions from RETRO

  • GOCART aerosol parameterization


Met products
MET Products:

  • “Standard” variables at multiple pressure levels

  • Simulated radar reflectivity

  • Convective fields (convective precip, etc.)

  • Thermodynamic Diagrams

Sim. Radar Reflectivity

Total 24 h Precip



Chem products
CHEM Products:

CO O3 NO

NO2

CH4

SO2

Surface CO

200 hPa Ozone

Post mission
Post Mission:

  • Finer horizontal resolution

    • 1-2 km grid spacing

    • Explicitly resolve convection

  • ICs and BCs from GFS final analyses

    • Includes observations

    • Better representation of atmosphere
