HYDROS is a new
$170M NASA satellite mission that will provide the first global
observations of daily surface freeze/thaw state and soil moisture
conditions, enabling new hydrological applications and new scientific
investigations of global change and atmospheric predictability.Â Soil moisture and freeze/thaw define the land hydrosphere
state that regulates land-atmosphere exchanges of water, energy
and trace gases. These factors, in turn, regulate regional weather
patterns and land ecosystem function. The information provided by
HYDROS will likely result in dramatic improvements in regional weather
forecast accuracy, regional forest and rangeland health and productivity
assessments, and drought and fire hazard mapping.
for launch in 2009, HYDROS will inaugurate a new generation of satellite
active and passive microwave remote sensing measurements of the
land surface to enable investigations of water and carbon cycle
interactions and associated impacts to regional and global ecosystems.
HYDROS builds on a heritage of ground, airborne and satellite measurements
that have established the utility of microwave remote sensing for
landscape monitoring under night, day and virtually all weather
will be merged with data from weather station networks and other
satellites in a state-of-the-art land data assimilation system,
delivering the most comprehensive view ever of the land hydrosphere.
The HYDROS mission
is a multi-institutional and international effort that includes
researchers from The University of Montana, NASA, MIT, USDA Agricultural
Research Service, Department of Defense, Canadian Space Agency.Â
John Kimball and Dr.
Steve Running with The University of Montana's Flathead Lake Biological
Station (FLBS) and Numerical Terradynamic Simulation Group (NTSG)
are members of the HYDROS mission science team responsible for developing
science applications for HYDROS, and developing and implementing
HYDROS freeze-thaw detection software and product validation protocols.
The University of Montana NASA ESIP is also the primary HYDROS global
freeze/thaw data processing facility.
