This study used one year of in situ water vapor isotopologue measurements collected at the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) user facility observatory located on Graciosa Island, Azores. Low clouds have an especially strong feedback over the ocean and previous studies have primarily focused on low clouds in the subtropics. This means that the Azores location in the transition between subtropical and mid-latitude oceanic areas represents an opportunity to study the connection between water vapor isotopologues and mixing processes that determine low-cloud feedback in an underrepresented setting with different seasonal dynamics. The DOE ARM facility on Graciosa Island presents the opportunity to complement water vapor isotopologue measurements with a suite of instruments capable of measuring changing atmospheric conditions.
