NOAA-NIST Meeting on Calibration and Climate Data Records
14 January 2008

A one day NOAA-National Institute of Standards and Technology (NIST) Meeting on Calibration and Climate Data Records was held at the NOAA Science Center on January 14, 2008. The primary meeting purpose was to share information about calibration issues related to developing long- term climate data records from several long-time NOAA, DMSP and Taiwan satellite instruments such as Microwave Sounding Unit (MSU), High Resolution Infrared Radiation Sounder (HIRS), Stratospheric Sounding Unit (SSU), Special Sensor Microwave/Imager (SSM/I), and Global Positioning System (GPS) Radio Occultation (GPSRO). Meeting attendees include scientists from NOAA, NIST, NASA, Air Force Institute of Technology (AFIT), and National Center for Atmospheric Research (NCAR). A total of 11 talks were presented at the meeting by NOAA, NIST, and NCAR scientists. The NOAA and NCAR presentations mainly focused on identifying instrument calibration issues during the process of radiance data generation and climate data record development, while the NIST presentations intended to provide reasons and solutions for some of these issues from the instrument design and algorithm development points of view. Discussions surrounding these presentations were lively and fruitful. In conclusion, the meeting builds steps toward further collaborative efforts across NOAA, NIST, and other agencies to resolve the existing calibration issues of satellite instruments, as well as to analyze climate data record uncertainties.
