Download Evaluation of WRFchem needs measurements at various sites

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
• ….
