JDW

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.
