NOAA@NSIDC's IPY Activities

The NOAA Arctic Research Program (ARP) funded NOAA@NSIDC to provide data management support for some of its Study of Environmental Arctic Change (SEARCH) activities. SEARCH program researchers need long-term and pan-arctic observations in order to detect climate change and to put change in context within space and time. NOAA SEARCH activities were ARP's contribution to the 2007-2008 International Polar Year (IPY). See the NOAA ARP Study of Environmental Arctic Change (SEARCH) Web site for more information.

Highlights of our work are below; the Final Report, September 2006 (PDF, 2.7 MB) has a more complete account.

Prototype Cryospheric Climate Indicators

Continuous records of soil temperature, vegetation greenness, and sea ice extent are used to give an at-a-glance picture of a changing Arctic. These prototype Cryospheric Climate Indicators were developed to supplement the indicators on the NOAA Arctic Change Web site. Visit the Arctic Change: A Near-Real-Time Arctic Change Indicator Web site to see these indicators of climate.

Funding constraints prevented us from developing these prototypes fully. The Sea Ice Index was an exception. With NOAA support, the index was extended back in time to 1979 with satellite passive microwave data from the Scanning Multi-channel Microwave Radiometer (SMMR) instrument. Prior to this instrument cross-calibration work, which took place in 2004, the popular Sea Ice Index time series began in 1988 with passive microwave data from the Special Sensor Microwave Image (SSM/I) instrument data.

Precipitation Data

For inventoried data sets, documented overlap between them, and acquired and published precipitation data.

Precipitation data sets published as part of this work are the following:

Precipitation data set inventory and overlap assessments, though dated, may be useful. See the Precipitation Data Set Station Lists and Overlap Analysis Web page for these inventories and assessments.
