Global Temperature September 2016 Preliminary

The September preliminary Climate Forecast System Reanalysis (CFSR) monthly global surface temperature anomaly estimates from the University of Maine Climate Change Institute (UM CCI) and from WeatherBELL (WxBELL) show a slight drop from August with levels similar to July as can be seen in the graph below.  The graph includes monthly estimates beginning January 2014.  The preliminary UM CCI global average temperature estimate of 15.92C ties the previous highest September 2003 CFSR estimate, for records beginning 1979.


Also shown for comparison are monthly global temperature anomaly estimates from six other major sources, including lower tropospheric estimates from the University of Alabama at Huntsville (UAH) and Remote Sensing Systems (RSS), and global surface temperature anomaly estimates from the US National Center for Environmental Information (NCEI), US National Aeronautics and Space Administration (NASA) Goddard Institute of Space Studies (GISS), the UK Hadley Climate Research Unit Temperature version 4 (CRUT4), and the Berkeley Earth Surface Temperature (BEST), all  final through August 2016.  All estimates have been synced to the latest climatological reference period 1981-2010.
