## NPOESS Preparatory Project (NPP)& Visible Infrared Imaging Radiometer Suite (VIIRS)Diane E. Wickland, Program ScientistMay 14, 2008

## National Polar Orbiting Environmental Satellite   System (NPOESS) Preparatory Project (NPP)

- NPP is the bridge mission between the NASA Earth Observing System (EOS) research satellites and the NPOESS operational environmental satellite system.
- NPP will provide continuity of the research-quality time series data products started with NASA’s EOS missions (i.e., Terra, Aqua, Aura).
- The NPOESS system is being developed to provide both “operational” data, for weather forecasting and real-time applications as well as “climate-quality” (= research-quality) data for long-term, multi-satellite, measurements of key environmental parameters.**      **

## NPP Science Goals

- NPP will continue the time series of moderate-resolution climate-quality observations of:
- atmospheric ozone **(OMPS)**
- clouds and aerosols **(VIIRS)**
- land cover and vegetation biophysical properties **(VIIRS)**
- ocean biological and biogeochemical properties **(VIIRS)**
- sea and land surface temperatures **(VIIRS)**
- temperature and moisture profiles in the atmosphere **(CrIS/ATMS)**
-  NPP will enable inter-comparison and cross-calibration of selected EOS and NPOESS measurements to ensure a climate-quality time series
-  These observations are needed for work in support of Presidential Initiatives on Climate Change Research, the U.S. Integrated Earth Observation System, and the Ocean Action Plan. The ozone observations are Congressionally mandated.

## NPP Recent Developments

-  Launch re-baselined to June 2010
-  Budget re-profiled
-  Some climate sensors restored:
- OMPS Limb restored
- CERES added
-  PEATEs asked to help scope potential data production options

## NPP Science Team:  Activities & Issues

- Status of the EDRs:  what we do and do not know about their character and quality for science
- need a concise summary; HQ briefing
- Shared MODIS & VIIRS ESDR funding; how to achieve the “right” balance
- NASA’s role in calibration & validation of VIIRS; what does the NPP Science team need to do to evaluate the EDRs; what type of support should NASA provide to the IPO
- NPP Science Team fate post-launch of NPP
- Launch 6/10; current awards through 11/10-1/11
- Role of the PEATEs: what they are charged to do, what they are able to do, and what they may or may not be asked to do in the future
- NASA science role when NPOESS C1 launches

## NPP Science Team:  This Meeting

- Let’s re-engage regarding NPP and its EDRs
- ensure we agree on who is involved, doing what
- plan a concise summary of what we have learned so far
- Let’s share our plans for ESDRs
- Let’s get any other concerns or issues regarding near-term implementation out and resolved
- Let’s talk about the continuity of systematic observations
- try to focus on what is needs to be done (more than on who does it)
- think about long-term priorities
