The world's population growth is increasingly concentrated in urban
areas and this trend is expected to continue in the
future. Urbanization has a profound impact on carbon dynamics, leading
to increases in anthropogenic carbon dioxide (CO2) emissions and
decreases in biogenic fluxes from these areas. We present Year 1
results from a measurement network and an accompanying atmospheric
modeling framework for downscaling the current NASA CMS flux products
to regional and local scales. These spatially and temporally resolved
estimates of biogenic and anthropogenic fluxes are central to meeting
greenhouse gas emissions reductions goals, and they complement Monitoring,
Reporting, and Verification (MRV). Our research focuses on the
Northeast corridor (Boston MA - Washington DC megalopolis), where
about 17% of the U.S. population lives on less than 2% of the nation's
land area, making it a key source of US anthropogenic CO2 emissions.
The research has progressed along three main lines: 1)
High-resolution transport modeling (WRF-STILT) customized and verified
for the region, 2) High-resolution CO2 flux model incorporating
anthropogenic emissions estimates and the CASA model (including its
0.5-deg resolution variant that provides the foundational biosphere
model for the current CMS Flux Product and nested higher resolution
runs to represent the scale sensitivity within heterogeneous urban
areas), and 3) Inverse CO2 flux estimates corresponding to in-situ and
remote CO2 observations in and around Boston, New York City, and
Washington DC. During the first year we have completed baseline WRF
simulations, analyzed sensitivity experiments for varying WRF
configurations, and deployed two mini Micro Pulse LiDARs for remotely
sensing planetary boundary layer characteristics; quality-controlled
and cross-calibrated CO2 measurements from the Boston and Earth
Networks measurement sites; generated high-resolution a priori
biospheric and anthropogenic flux estimates; and tested aspects of the
inversion framework using data from a methane study for Boston.
