MOBILE DATA ACQUISITION AND PROCESSING IN SUPPORT OF AN URBAN HEAT ISLAND STUDY
نویسندگان
چکیده
Abstract. Global warming and changes in Earth’s weather patterns are the main consequences of climate change, bioclimate discomfort has significant public health problems, especially for elderly. Normally, thermal characteristics urban areas poor due to a phenomenon known as heat island. Mobile fixed temperature measurements were performed on 19 March 2021 city Bologna, Italy. took place with car, along 75-km transect, starting at 22:16 duration 2 hours 41 minutes, while done using 15 present stations also placing five thermometers center. Various interpolation models (i.e., Traditional, Voronoi Tessellation, Trends, Triangulated Irregular Networks, Inverse Distance Weighting Kriging) applied correct mobile data. Kriging fulfilled best result correlation coefficient 0.99 compared raw temperatures.

We are all familiar with the fact that cities are generally warmer than the surrounding, more rural areas. We see it referenced most nights in our television weather reports. It is especially significant on nights with clear skies and light winds which favor radiational cooling. This is most significant in the rural areas but in the city, the excess heat absorbed during the day and the local he...

متن کاملInvestigation of changes in surface urban heat-island (SUHI) in day and night using multi-temporal MODIS sensor data products (Case Study: Tehran metropolitan)
The term urban heat island (UHI), described the phenomenon of climate change in urban areas compared with surrounding rural areas. UHI effects include: increasing in energy and water consumption, air pollution expansion and interfering in thermal comfort. Surface urban heat island (SUHI) contains patterns of land surface temperature (LST) in urban areas that has interaction with UHI in urban ca...
