In 2004 the INTEX Ozonesonde Network
Study provided a consistent network of vertical ozone profiles from the
troposphere and stratosphere with higher vertical resolution than aircraft
and satellites could provide. Eleven stations, including Huntsville,
participated in the coordinated launches between 1 July - 15 August ussing
ECC ozonesondes across the board (Thompson et al., in press 2007a).
A similiar campaign was launched in 2006 (IONS06) coordinating twenty-two
ozonesonde stations, one of which was right here in Huntsville. The data
collected between 1 August - 15 September 2006 has been made available
on the IONS06 homepage. Currently, Rochelle Williams is
working with the available data in order to identify a high in tropospheric
ozone over the southeastern United States. She will be using trajectory
analysis to determine the origin of this high in ozone with lightning
generated NOx being the primary suspect.
AIRS Campaign at Chesapeake Lighthouse
June 2003, Jing Song and Mike Newchurch went to the Chesapeake Lighthouse
to join Wallace McMillan/UMBC, Kurt Lightner/UMBC, Kevin McCann/UMBC,
Michele McCourt/UMBC, Eric Hintsa/Woods Hole, and Amanda Roberts/Woods
Hole for an AIRS validation campaign. Song and Newchurch flew ozonesondes
to measure ozone/temperature/humidity; McCourt, McMillan, and Lighter
flew radiosondes to measure temperature and humidity; McMillan, Lighter
and McCourt made FTIR measurements with the BBAERI; McCann measured
aerosol backscatter with the 532-micron ELF lidar; and Hintsa and Roberts
measured surface ozone for an ocean surface instrument development
program. Lightner and McMillan are also measuring insitu surface O3
and CO and take all-sky images.
Lighter devised a very effective system for shielding the balloon during
inflation using a parachute attached to the helicopter landing pad.
This system allowed the first successful daytime and nighttime ozonesonde
launches from the Chesapeake Lighthouse on 2 and 3 June 2003.
SOS Campaign (1999)
The Southern Oxidants Study (SOS) is
a strategic alliance of research scientists, engineers, and air quality
managers from universities, federal and state governments, industry,
and public interest groups. In SOS, these groups work to design and execute
scientific research and assessment programs that will increase understanding
of the accumulation of ozone, other oxidants, and fine particulate matter
in the atmosphere near the ground. SOS was formed in June 1988 when a
group of 60 concerned scientists, federal and state agency officials,
and key industry representatives gathered at the Georgia Institute of
Technology in Atlanta, GA. The group considered the question of why ozone
abatement measures had been largely unsuccessful, particularly in the
South. To read more about the program, please see the SOS homepage.
The Southern Oxidants Study, Nashville
99 campaign ran from June 14th through July 16th 1999. The group
was located at the Nashville Old Hickory Weather Service Office in Tennessee.
The Huntsville Ozonesonde Station's role in the Southern Oxidants Study
in Nashville was to launch daily ozonesondes throughout the duration
of the 99 campaign.
