What is it about?
We show temperature changes in the Earth's atmosphere from the troposphere to the stratosphere up to 50 km. We analyzed observations for 1979–2018, with more than 40 years of meteorological satellite data and novel observations from GPS radio occultation at hand. Over the last four decades, the lowermost atmosphere has warmed significantly due to increase in greenhouse gases, while the layer above has cooled (from ozone changes and greenhouse gas radiation into space). The observed warming in the troposphere is even more markedly than surface warming.

Why is it important?
We inform about the current state of temperature changes in the Earth's atmosphere using the latest available observational records. Consistent and continuous observations of air temperatures are critical for improving understanding of climate change.
