This dataset was collected at residential yards in six Metropolitan Statistical Areas: Boston (Massachusetts), Minneapolis-St. Paul (Minnesota), Baltimore (Maryland), Miami (Florida), Los Angeles (California), and Phoenix (Arizona). The yards were categorized as "traditional with high fertilizer input", "traditional with low fertilizer input", "water conserving", and "wildlife friendly". In addition to lawn evapotranspiration, the dataset includes soil water content, the intensity of solar radiation, atmospheric temperature and humidity, wind speed and more. For more details, see Grijseels et al. (2023).

This dataset consists of sap flux and environmental data continuously collected in a stand of loblolly pine trees growing in a residential backyard in the northeast of Tallahassee in 2020-2022. Over the course of the study, the trees were treated with an insecticide, one tree died, and two trees were cut down due to an outbreak of bark beetles. The site received no regular irrigation or fertilizer inputs. Studied loblolly pine trees were about 84 years old and a part of a mixed species stand with several other tree species, with an understory of herbaceous plants, woody shrubs, and the mix of groundcovers. Some of the plantings received occasional irrigation, and the groundcover was regularly mowed. Sap flux was measured with Granier-type thermal dissipation probes at 1.35 m height in the outer 2 cm of sapwood. The dataset was collected as part of a study of Tallahassee urban forest transpiration. For more details, see Litvak and Pataki (2024).

This dataset contains daily sap flux and transpiration collected in greater Los Angeles area in 2007 and 2008. The study sites were located on Sycamore Avenue in Los Angeles, at the Starr Ranch Sanctuary, on the Irvine campus of the University of California, at the Los Angeles Zoo and Botanical Gardens, at the Arboretum at Cal State Fullerton, at the Los Angeles Police Department’s Revolver and Athletic Club, and at the Los Angeles County Arboretum and Botanic Garden. The studied trees include London planetree (Platanus × hybrida Brot.), California sycamore (Platanus racemosa Nutt.), coast live oak (Quercus agrifolia Née), Canary Island pine (Pinus canariensis C.Sm. ex D.C.), jacaranda (Jacaranda mimosifolia D.Don), laurel sumac (Malosma laurina (Nutt.) Nutt. ex Abrams), rose gum (Eucalyptus grandis W.Hill), coast redwood (Sequoia sempervirens (D.Don) Endl.), Chinese elm (Ulmus parvifolia Jacq.), lacebark tree (Brachychiton discolor F.Muell.), kurrajong (Brachychiton populneus (Schott & Endl.) R.Br.), crape myrtle (Lagerstroemia indica L.), honey locust (Gleditsia triacanthos L.), goldenrain tree (Koelreuteria paniculata Laxm.), and Chinese banyan (Ficus microcarpa L.f.). Sap flux values are daily sums of data collected every 30 seconds by sap flux sensors installed in sapwood and stored as 30-minute averages by Campbell Scientific dataloggers. The data are quality controlled and processed to estimate average tree-level stand transpiration. For more details, see Pataki et al. (2011) and Litvak et al. (2012).
