NOAA: March 2009 Tenth Warmest on Record for Global Temperatures

April 16, 2009

The combined global land and ocean surface average temperature for March 2009 was the 10th warmest since records began in 1880, according to an analysis by NOAA’s National Climatic Data Center in Asheville, N.C.

The analyses in NCDC’s global reports 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 NCDC’s processing algorithms.
