FIELD EXPERIMENTS

TCAP
The Department of Energy (DOE) is conducting the
Two Column Aerosol Project (TCAP) with several contributions from
NASA. TCAP is designed to provide measurements of aerosol composition,
size, and optical properties within two columns of air off the coast
of North America. The field campaign will deploy ground-based
instruments on Cape Cod, Massachusetts for a 12-month period starting
in the summer of 2012, supplemented with intensive aircraft
observation periods in summer and winter using the ARM Aerial Facility’s Gulfstream-1(G-1)
research aircraft. Our new airborne Spectrometer for Sky-Scanning,
Sun-Tracking Atmospheric Research (4STAR) has been selected for flight
on the G-1 in TCAP.
4STAR will directly yield atmospheric direct-beam
transmittance, leading to aerosol optical depth and extinction between
the G-1 stair-step segments. In addition, 4STAR's full spectral
measurements are expected to provide improved retrieval of trace
gases, and 4STAR's sky-scanning measurements will enable retrievals of
size distribution, complex refractive index, and shape, analogous to
retrievals from the ground-based AERONET sun-sky photometers.

COAST
In Fall 2011 NASA is conducting the flight phase of the Coastal and Ocean Airborne Science Testbed (COAST) project. COAST is part of NASA's Hands On Project Experience (HOPE) program. COAST objectives include:
- Develop a flight-tested instrument suite suitable
for remote sensing of optical properties in the coastal zone
- Collect measurements of optical properties in the coastal zone enabling Ocean Biology and Biogeochemistry science
The
COAST payload includes AATS-14, which will measure solar direct-beam
transmission through the atmosphere at 14 wavelengths and provide data
products on Aerosol Optical Depth (AOD) and water vapor column
content. AATS data will be used to correct atmospheric effects on
COAST ocean imagery.

ARCTAS
In Spring and Summer 2008 NASA conducted a campaign
called Arctic Research of the Composition of the Troposphere from
Aircraft and Satellites (ARCTAS).
The spring deployment targeted arctic haze, anthropogenic pollution in
general, stratosphere-troposphere exchange, and sunrise photochemistry.
The summer deployment targeted boreal forest fires,
stratosphere-troposphere exchange, and summertime photochemistry. ARCTAS
is part of the international IPY/POLARCAT arctic field program for atmospheric composition.

INTEX-B / MILAGRO
In March 2006 several coordinated experiments studied gaseous and
aerosol pollutants originating primarily in Mexico City. The March phase
of INTEX-B (the Intercontinental Chemical Transport Experiment) was closely coordinated with MILAGRO (Megacity Initiative: Local and Global Research Observations). Our airborne sunphotometer, AATS-14, flew on the J31
aircraft based in Veracruz, Mexico, measuring aerosols and water vapor
in outflow from Mexico City and biomass burning regions of Mexico and
Central America.

INTEX - ITCT - ICARTT
In Summer 2004 several coordinated experiments
studied air quality, intercontinental transport, and radiation balance
in air masses carried across the US and over the Atlantic to Europe.
NASA organized INTEX-NA. NOAA organized NEAQS - ITCT 2004. And Europeans organized ITOP. ICARTT was formed to enhance the synergy between ITCT, INTEX, and ITOP.
