What is it about?

Surface and air temperatures are measured just two meters apart, so it might seem that they carry the same information. Here we show that these temperature measurements respond rather differently to whether the surface evaporates or not.

Why is it important?

These findings appear important to be considered when using, analyzing, or interpreting temperature data in studies dealing with climate change, hydrology, or land‐atmosphere interactions.


This study presents a new methodology of using diurnal evolution of temperatures in response to solar radiation for understanding evaporative conditions and boundary layer processes. The study is significant to understand land-atmosphere interaction using observations and a simple physical boundary layer model.
