The Impact of Seasonality and Land Cover on the Consistency of Relationship between Air Temperature and LST Derived from Landsat 7 and MODIS at a Local Scale: A Case Study in Southern Ontario

Land surface temperature (LST) and air (Tair) have been commonly used to analyze urban heat island (UHI) effects throughout the world, with noted variations based on vegetation distribution. This research has compared time series LST data acquired from Moderate Resolution Imaging Spectroradiometer (MODIS) platforms, Landsat 7 Enhanced Thematic Mapper (ETM+) Tair weather stations in Southern Ontario area. The influence of spatial resolution, land cover, vegetated surfaces, seasonality relationship between situ were examined. objective is identify seasonal differences amongst these different resolution products Tair, along causes for at a localized scale. Results show that MODIS Terra had stronger relationships than those Aqua. demonstrated weaker correlations sparsely areas during summer. Due winter’s ability smooth heterogenous both showed winter summer over every except coarse resolutions forested surfaces.
