Short summary

Increasing atmospheric humidity and convective precipitation over land provide evidence of intensification of the hydrologic cycle. We present the first multi-annual isotope (oxygen and deuterium) water vapor observations from a very tall tower (185 m) in the upper Midwest, United States, to diagnose the sources, transport, and fractionation of water vapor in the atmosphere. The results show a relatively high degree of summertime water recycling within the region (~30 % mean and ~60 % maximum).
