National Polar-Orbiting Operational Environmental Satellite System
(NPOESS ) Mission Update
National Polar-Orbiting Operational Environmental Satellite
System (NPOESS ) Mission Update (con’t)
Continuity of Polar Operational Satellite Programs
NPOESS Sensor Updates
• Visible Infrared Imaging Radiometer Suite (VIIRS) –Reduced
Coverage (No mid-morning orbit)
• Conical Scanning Microwave Imager (CMIS) –Reduced
Capability
• Capability and Coverage Reductions in Science Priority
VIIRS: NPOESS Mitigation
• VIIRS is intended to succeed the MODIS instruments on Aqua and
Terra
• VIIRS was planned to fly on all six of the original NPOESS missions
• The Certified NPOESS uses an AVHRR on the European MetOp
Mission in the mid-AM orbit.
• A VIIRS in the mid-AM orbit would continue the climate data
products presently produced by MODIS on Terra
Conical Microwave Imaging Scanner (CMIS)
(Reduced Capability Sensor)
•
Provides sea surface temperatures, sea ice and snow cover extents
•
Ability to obtain both day and night measurements
•
CMIS data are currently provided by the Aqua AMSR-E instrument, the SeaWinds
scatterometer on the QuikSCATMission, and the experimental surface vector wind sensor
from the Navy’s Windsat/Coriolis Mission
–
•
Some of these data also provided by SSMIS on DMSP Missions
CMIS was originally a six-band system with vertical and horizontal polarization in each band
–
–
–
Descoped to a less expensive system known as Microwave Imager/Sounder (MIS)
MIS not yet clearly defined in detail
Scheduled for NPOESS C2 (2016)
Integrated Earth Observing
Satellite Missions
Implementation of Planned Earth
Observing Systems
Phases:
1: 2007-2009: End of legacy and ongoing satellite missions and
instruments of significant relevance to cryosphere monitoring .
2: 2010-2015: Plans & concepts for ample global space observing
systems for cryospheric monitoring becoming reality, but at considerable
cost.
3: After 2015: Optimistically continued implementation of planned
recommended space missions that will fill key observational gaps.
