Boundary layer experimental data for evaluation of WRFchem

1
Boundary layer experimental data for evaluation
of WRFchem

• Facts and status quo
• WRFchem is well evaluated for East Coast
• WRF is well evaluated for test-bed
• WRF did better than the National Hurricane Center
  model for Katrina
• Research question to be addressed
• How does WRFchem perform in AK?

Evaluation of WRFchem needs measurements at
various sites inside and outside of Fbks and
initial data

• From NCEP, EPA, USGS, etc.
• Spatial and temporal distribution of emission
  rates from ground and air traffic, power plants,
  households
• Initial background concentration of air
  constituents
• NCEP reanalysis data
• Data on vegetation fraction, soil and vegetation
  distributions

• From boundary layer experiment
• Hourly data of SO2, NO2, N2O, H2O2, O3, VOC,
  HNO3, PM10, PM2.5 concentrations, T, q, v
• Hourly average fluxes of Rnet, H, LvE, G, P,
  trace gases
• Vertical profiles of state variables,
  concentrations, fluxes desirable at least at
  three sites
• Satellite data for cloud distribution
• Active layer depth
• Soil temperature and moisture at various depths
• ..

Proposed outcomes

• Test case of performance of WRFchem in the Arctic
• Find niche for improvement/model further
  development
• Make judgment on fate of trace gases
• Co-authorship for those who provide data useful
  for my research question How is WRFchem doing in
  the Arctic?
• Maybe proposal for experiment-modeling study
• .
