NOAA: 2009 Global Temperatures Well Above Average; Slightly Above-Average for U.S.

U.S. precipitation above normal for 2009

December 8, 2009

Global surface temperatures for 2009 will be well above the long-term average, while the annual temperature for the contiguous United States will likely be above the long-term average, according to a preliminary analysis by NOAA’s National Climatic Data Center in Asheville, N.C. The analysis is based on global records, which began in 1880 and U.S. records beginning in 1895. The NCDC analysis is part of the suite of climate services NOAA provides.

NOAA’s preliminary reports, which assess the current state of the climate, are released soon after the end of each month. These analyses are based on preliminary data, which are subject to revision. Additional quality control is applied to the data when late reports are received several weeks after the end of the month and as increased scientific methods improve NOAA’s processing algorithms.

Scientists, researchers, and leaders in government and industry use NOAA’s monthly reports to help track trends and other changes in the world's climate. This climate service has a wide range of practical uses, from helping farmers know what and when to plant, to guiding resource managers with critical decisions about water, energy and other vital assets.

NOAA understands and predicts changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and conserves and manages our coastal and marine resources.
