Global atmospheric temperatures in March as measured by satellite instruments and analysed by RSS shows that it was the warmest March and third warmest month since satellite monitoring began – following on from February which was the warmest month in the satellite record.

March 2016 was the warmest March on record in terms of atmospheric temperatures measured by satellite, according to data released by US firm Remote Sensing Systems (RSS).

The mean global temperature anomaly – or variance to the long term average – for the lower troposphere during March was +0.84oC, down on the +0.98oC reported in February.

El Niño drove up the global temperature

Global atmospheric temperatures in March were driven up by the El Niño Pacific Ocean warming event. This pushed up the temperature anomaly in the tropics to +1.00oC in March making March 2016 the second warmest March in the tropics – just behind March 1998 which registered a marginally (but statistically insignificantly) higher anomaly of +1.03oC.

The RSS result for March 2016 agrees with a different analysis of satellite data by the University of Alabama in Huntsville (UAH). Both analyses rank the global anomaly in March as warmest March and the third warmest month in the satellite era.
