Initial Temperature Data for August

September 12, 2013; 3:14 PM

Average global temperatures for the lower troposphere during last month averaged 0.167 degrees C or 0.30 F above the 1979-1998 normal, according to Remote Sensing Systems (RSS).

RSS uses microwave sounding data on board satellites to obtain their temperature anomaly data.

August 2013 now ranks as the 14th warmest August in the satellite record.

The RSS image below shows the August 2013 global temperature anomalies. Reds show above-normal temperatures, while blues indicate lower-than-normal temperatures.

For the continental U.S., the temperature averaged +0.189 C or +0.34 F above normal.

Longer-term trends

The RSS image below shows the overall temperature trend for most of the globe during the satellite era between 1979 and 2012.

As you can see, most of the warming has been over the northern latitudes.

Even though temperature anomalies have been shown on average to be lower with the satellite data compared to the observed surface data, their longer-term trends are very similar.
