This is a companion dataset for the Universal Thermal Climate Index (UTCI) over Austin, Texas [ https://doi.org/10.5281/zenodo.10870068 ] 1. Dataset description This dataset uses the Mean Radiant Temperature (TMRT) calculated using the the SOLWEIG model (Lindberg et al., 2018) to optimize tree planting locations in Austin, Texas using the tree planter tool (Wallenberg et al., 2022). Only the public space was used in optimization and 250 trees were optimally located within 1-mile buffer zones. Followin the City of Austin guidelines, the height and crown diameters of the optimized trees were both ~6 meters and tree trunk zone height was ~2 meters above ground. The trees were optimized for a typical clear-sky weather during Fall season. 2. Data availiablity Data is available for entire Austin, Texas except a few neighborhoods. 3. Data format The data is available in ESRI shapefile (.shp). Each point represents a potential tree planting location. References Lindberg, F., Holmer, B., & Thorsson, S. (2008).
