High-Resolution Wind Fields for Constraining
North American Fluxes of Carbon Dioxide in a
Geostatistical Inverse Modeling Framework
PI Anna M. Michalak, University of Michigan
Award number SMD-06-0249
Objective of Usage

• Produce high-quality meteorological fields that
  cover North America at hourly-resolution,
  spanning multiple years, and nested down to 2-km
  at target sites with continuous, long-term
  monitoring of CO2.
• Simulations will support project that seeks to
  infer sources and sinks of CO2 in North America
  on fine spatial and temporal resolutions.

Identify the codes to be run

• Weather Research Forecasting (WRF) mesoscale
  atmospheric model

Sensitivity of measurements to surface fluxes
from STILT model, integrated over the month of
September, 2004
Scientific Impact
Key Milestones

• Study will produce
• CO2 flux estimates over North America at
  currently unavailable spatial resolution (1ox1o)
• Atmospheric-data derived estimates of the
  influence of auxiliary biophysical variables on
  the magnitude and variability of North American
  fluxes

• Test different WRF configurations for generating
  high-resolution meteorological fields 5/07
• Deliver science-quality dataset for one target
  site (WLEF) and compare atmospheric simulations
  with measurements to derive atmospheric error
  estimates 7/07
• Produce met fields for all target tower
  sites 12/07
