The Portable Ice Nucleation Experiment (PINE) instrument of the Atmospheric Science group at the Karlsruhe Institute of Technology (Germany) was shipped to Aeghion and operated at our Valimitika experimental lemon orchard from March 27 to May 7, 2023. This is a state-of-the-art instrument to monitor airborne ice nucleating particles in a continuous mode and in real time. We investigated the presence, number and activity of ice forming particles in the atmosphere of the orchard; ice forming particles immigrating at or emigrating from agricultural sources. This is one of the few studies of its kind worldwide. The ongoing analysis of data will shed light into the relationship between ice nucleating particles of biological and inorganic origins on the plant surface and in the atmosphere of an orchard. We are grateful to the owner of the orchard for hosting this instrument.
