WB-57 Missions

Atmospheric Research Missions

CRYSTAL - FACE (Cirrus Regional Study of Tropical Anvils and Cirrus Layers - Florida Area Cirrus Experiment)
Summer 2002
http://research.hq.nasa.gov/code_y/nra/current/NRA-01-OES-02/index.html
CRYSTAL-FACE was a focused mission of modeling, observations and integrated analyses designed to investigate tropical cirrus cloud systems and their roles in both regional and global climates.

CWVCS (Clouds and Water Vapor in the Climate System)
Summer 2001
http://www.arp.harvard.edu/field/wb57cr/index.html
The CWVCS mission was a two-week, remote site deployment to San Jose, Costa Rica. The objective was to attack unanswered scientific questions that lie at the intersection of atmospheric radiation, dynamics, chemistry, and climate.

ACCENT (Atmospheric Chemistry of Combustion Emissions Near the Tropopause)
Spring 1999, Fall 1999, Fall 2000
http://telsci.arc.nasa.gov/pages/accent.html
The ACCENT missions were multi-agency sponsored efforts to investigate the chemistry of rocket and aircraft emissions in the upper troposphere (UT) and lower stratosphere (LS). The ACCENT missions also collected near tropopause gaseous and aerosol data in the tropics and near and above hurricane Floyd.

WAM (WB-57 Aerosol Mission)
Spring 1998
http://raf.atd.ucar.edu/~darrel/wam.html
WAM made measurements of the chemical composition of individual atmospheric aerosol particles, accompanied by particle sizing, gaseous tracer measurements, very accurate water vapor and total water, radiometric radiance measurements and fast response, and accurate measurements of pressure, temperature, and winds. The objective of the mission was to characterize the chemical composition of individual aerosol particles in the upper troposphere and lower stratosphere as a function of size and gaseous composition of the air.

RISO (Rocket Impacts on Stratospheric Ozone)
1996-1998
http://timonf.aero.org/envsys/RISO.html
In response to environmental concerns pertaining to the effects of launch vehicle emissions on stratospheric ozone, the RISO program was developed to obtain new and unique data on the chemistry and dynamics of stratospheric rocket exhaust plumes. Rocket plumes investigated include those of the Titan, Space Shuttle, Delta, Atlas, and Athena rockets. The data collected by the RISO program is being used to help assess the local and global response of the stratosphere to emissions from launch vehicles.
