Over the last decade, the tri-agency Integrated Program Office (IPO), comprised of the National Oceanic and Atmospheric
Administration (NOAA), the Department of Defense (DoD), and the National Aeronautics and Space Administration (NASA), has
been managing the development of the National Polar-orbiting Operational Environmental Satellite System (NPOESS). Once
operational later this decade, NPOESS will replace NOAA's Polar-orbiting Operational Environmental Satellites (POES) and
DoD's Defense Meteorological Satellite Program (DMSP) systems. The IPO, through its Acquisition and Operations contractor,
Northrop Grumman, will launch NPOESS spacecraft into three orbital planes to provide a single, national system capable of
satisfying both civil and national security requirements for space-based, remotely sensed environmental data. With the
development of NPOESS, we are evolving the existing "weather" satellites into integrated environmental observing systems by
expanding our capabilities to observe, assess, and predict the total Earth system - ocean, atmosphere, land, and the space
environment. NPOESS will transform today's short-term, space-based ocean research missions into a sustained, operational
ocean remote sensing observation program.
Land measurements comprise seven of the fifty-five user-validated requirements for geophysical measurements that will be made
by NPOESS sensors. In 1997, the IPO initiated a robust sensor risk reduction effort for early development of the critical
sensor suites and algorithms necessary to support NPOESS. In 2001, preliminary design efforts were completed for the last of
five critical imaging/sounding instruments for NPOESS. Land requirements have directly and substantially "driven" the
design of two NPOESS sensors: the Visible/Infrared Imager Radiometer Suite (VIIRS) and the Conical-scanning Microwave
Imager/Sounder (CMIS). Compared to the predecessor operational systems, NPOESS will deliver higher resolution (spatial and
temporal) and equivalent (or more) accurate measurements of surface albedo, vegetative index, imagery , land surface
temperature (LST), snow cover/snow depth, surface type, and soil moisture.
Early flight-testing of instruments will reduce development risk and demonstrate and validate global imaging and sounding
instruments, algorithms, and pre-operational ground systems prior to the first NPOESS flight. Four NPOESS sensors are
scheduled to fly on the joint NASA/IPO NPOESS Preparatory Project (NPP) mission in 2008. NPP will demonstrate the utility of
improved imaging and radiometric data for terrestrial applications, such vegetation mapping, landcover change, and fire
detection. NPP and NPOESS will help ensure continuity and extension of climate-quality measurements between NASA's Earth
Observing System Terra and Aqua research missions and NPOESS.
