Land surface temperature and urban heat island estimates for Australian capital cities, summer 2018-19

Brief description

Land surface temperature (LST) maps, and urban heat island (UHI) maps, for Australian capital cities, calculated over summer 2018-19.
Lineage: Land surface temperatures were calculated using data from the Landsat 8 thermal infrared sensor (TIRS) band 10. Each image was processed using the generalised single channel method of Jiménez-Muñoz et al. (2003, 2009). The required atmospheric parameters were obtained from publicly available observations by the Australian Government Bureau of Meteorology (BOM). The required land surface emissivity (LSE) values were estimated using the NDVI approach (Sobrino & Raissouni 2000). Urban Heat Island (UHI) was estimated by subtracting from the LST images an estimate of non-urban baseline temperature. This baseline was estimated by a first-order fit to the temperature of native vegetation within and around each urban centre.
