STATEMENT OF TASK

The NRC will augment the recommendations of the report Reconciling Observations of Global Temperature Change by writing a brief letter report that will advise NESDIS on actions that might be taken to improve the utility of upper air temperature measurements for the purpose of long-term climate monitoring. In this regard, the report will provide recommendations pertaining to MSU/AMSU sensor measurements from the next four NOAA environmental satellites planned for launch over the next 5 to 8 years. The report will also provide recommendations on extending and refining the radiosonde record for the purpose of temperature-trend monitoring. The letter report will suggest actions that might be taken to improve the quality of long-term temperature data records from MSU/AMSU and radiosondes in the following areas:

  • Satellite launch scheduling and replacement strategy

  • Satellite sensor calibration, including pre-launch and post-launch, as well as sensor and satellite stabilization

  • Temperature processing algorithms

  • Provision of adequate radiosonde data for comparison with MSU/AMSU data and long-term monitoring of atmospheric vertical structure

  • Provision of other ancillary data necessary in the diagnosis of temperature trends, including information from other channels aboard the NOAA polar orbiting satellites

  • Continuity of record

  • Data storage and access

  • Documentation and electronic access of metadata
