Overall Objectives of the Tiger Team Proposal 1. Evaluate satellite products for Air Quality (AQ) applications specific to understanding trace
gas burdens near and downwind of four main regions with active US Oil & Natural Gas
(ONG) extraction sites.
2. Characterize impact of ONG emissions on regional AQ including Appalachian Basin (PA,
MD, OH, and WV), Williston Basin (ND), and UT-CO-WY Basins.
3. Support AQ model/emission inventory comparisons using our combined satellite and in-situ
datasets.
Accomplishments in Year 1:
1. Experiments/Campaigns:
a. A. Thompson:
i. Completed the 4th
NASA DISCOVER-AQ deployment with NATIVE in
Colorado July-August 2014. At the NOAA Platteville site, methane, VOCs,
and other trace gases were measured with meteorological variables.
ii. Shared near real time campaign data analysis and air quality updates during
DISCOVER-AQ Colorado through social media using in situ and satellite
observations. (ie. Twitter - @MDGatorTeam, blog -
http://mdgatorteam.blogspot.com/, etc.)
iii. Began analyzing regional methane and related trace gas variability at the
surface and in the lower troposphere during all four deployments of the NASA
DISCOVER-AQ campaign (Edgewood, MD [2011]; Porterville, CA [2013];
Smith Point, TX [2013]; Platteville, CO [2014] Figures 1a &1b).
b. R. Dickerson:
i. Began flights to measure CO2 and CH4 from urban areas and oil and natural
gas operations (Figures 2a &2b).
ii. Established Cooperative Agreement with NIST for measurement technology
of greenhouse gas flux entitled the “Flux of Atmospheric Greenhouse Gases
in Maryland: FLAGG-MD.”
iii. Implemented improved chemical mechanism in the EPA regulatory models
CMAQ and CAMx for the Maryland SIP and used initial and boundary
conditions provided by AQAST colleagues.
iv. Investigated the sources of methane, ethane, and other trace species associated
with oil/gas production using in situ and satellite observations. (Figure 3a &
Schneising et al [2014])
v. Summarized for publication the use of NASA data from DISCOVER-AQ –
published in the journal Environmental Management.
c. D. Edwards / G. Pfister:
i. Completed the successful NCAR/NSF FRAPPE campaign in collaboration
with the 4th
deployment of NASA’s DISCOVER-AQ July/August 2014.
ii. Provided link to rich dataset of trace gases to characterize emissions from
ONG on regional and local scales in Colorado (Figure 3b).
2. Modeling/Emissions:
a. B. Pierce:
i. Compared OMI BEHR NO2 and 2008 WRAP and 2011 NEI emission
inventories, which show reasonable (0.3-0.6) correlations for urban areas and
