The [http://www.espo.nasa.gov/arctas/ Arctic Research of the Composition of the Troposphere from Aircraft and Satellites] (ARCTAS will take place during the Spring and Summer of 2008. This is a working document defining the main attributes of the GEOS-5 system that will be deployed in real-time in support of ARCTAS.


The [http://gmao.gsfc.nasa.gov/projects/arctas/ ARCTAS Forecasting Support at GSFC] page provides access to the main data products and web services.
The [http://www.espo.nasa.gov/glopac/ Global Hawk Pacific Mission] (GloPac) will take place during the Spring of 2010. Proposed flights of the Global Hawk for the Global Hawk Pacific Mission (GloPac) are to be conducted in support of the Aura Validation Experiment (AVE). This mission will take place out of Dryden Flight Research Center and is expected to encompass the entire offshore Pacific region with four to five 30 hour flights. The flights are designed to address various science objectives:
# Calidation and scientific collaboration with NASA earth-monitoring satellite missions, principally the Aura satellite,
# Observations of stratospheric trace gases in the upper troposphere and lower stratosphere from the mid-latitudes into the tropics,
# Sampling of polar stratospheric air and the break-up fragments of the air that move into the mid-latitudes,
# Measurements of dust, smoke, and pollution that cross the Pacific from Asia and Siberia,
# Measurements of streamers of moist air from the central tropical Pacific that move onto the West Coast of the United States (atmospheric rivers).
 
This is a working document defining the main attributes of the GEOS-5 system that will be deployed in real-time in support of GloPac.
