Environmental Monitoring in Support
of Civil and Defense Applications
Features• Rapid data delivery - 4 times faster than
legacy systems (JPSS-2 and beyond)
• Quickly react to changing conditions
• 10 times the data
• More accurate data for better forecasts
• International collaboration
Benefits• Critical inputs to weather forecast models
• Science quality data to users including
research scientists
• Continuity of climate data records
Earlier, more accurate forecasts and warnings can
mitigate the effects of major floods through longer
lead planning and better response.
Use of data from NASA's Earth Observation Satellite
sensors, which are precursors of the improved
sensors that will fly on JPSS, has demonstrated more
accurate hurricane forecasts and extended forecast
usefulness.

NOAA through NASA ,as its acquisition agent, will
procure the afternoon orbit assets that support its
civil weather and climate requirements and DoD
will independently procure assets for the morning
orbit military mission. Both agencies will continue
to share environmental measurements made by
the system and support the operations of a shared
common ground system.
Our valuable international partnership with the
Europeans will remain for support of the mid-
morning orbit, and NOAA will continue to pursue
additional partners for inclusion into the system.
Some work remains to develop the most effective
transition and alignment of responsibilities, as
well as to refine the launch readiness dates.
