Two field sites are located within Hawai‘i Volcanoes National Park (HavoNet) representing native forest and a forest invaded by an alien tree species, both within the cloud zone on the slopes of Kilauea Volcano on Hawai‘i Island. These sites are equipped with an extensive array of instruments measuring: RF, Ta, RH, WS, WD, Ts, SHF, SM, and downward and upward longwave and shortwave radiation fluxes. In addition, these sites are also equipped with eddy covariance sensors to monitor energy exchange and fluxes of water and carbon between the atmosphere and the ecosystem. Eddy covariance measurements are taken at 10-Hz, RF at a 1-minute interval, and all other climate measurements are recorded at 30 min intervals. These data are managed by the Giambelluca Ecohydrology Laboratory, University of Hawai‘i at Mānoa (https://sites.google.com/a/hawaii.edu/ecohydrology_lab/home).
