Urban areas have discrete differences in their land surface temperatures (LST) compared to rural areas. These regions are covered with impermeable materials with less vegetation and moisture. Consequently, this phenomenon causes major thermal intensities of different land surfaces, negatively impact people and environment. The objective of this project is to examine and to compare land surface temperature obtained from in-situ data and satellite-based observations in order to understand the diurnal variation and heat transfer at each surface type. The study utilizes series of hand held thermal infrared cameras and one Unmanned Aerial Vehicle (UAV) infrared camera to find land surface temperature of various surface types in New York City. It also provides a thorough analysis of the ground observations of different land surfaces by using a flux tower that collects measurements of all surface energy balance components for the first time in urban regions. The flux tower was planted on materials such as concrete, asphalt and rooftops to take the measurements through eddy covariance method. Additionally, the satellite observations from NOAA's latest generation of Geostationary Operational Environmental Satellites (GOES), known as the GOES-R Series, Landsat, and the Moderate Resolution Imaging Spectroradiometer (MODIS) LST products were compared to the exact locations of the ground-based data collected from the thermal cameras.
