DEVELOPMENT AND APPLICATION OF MOBILE OBSERVATION METHOD OF URBAN CLIMATE TO ANALYZE OCCURRENCE OF HEAT-ISLAND IN CHANGCHUNG CITY OF CHINA

The mobile observation method of air temperature was proposed to analyze occurrence of heat-island, and was applied in the central urban area of Changchung City of China in August 2007. Four routine observatories were placed, and also two bicycles with which the GPS receiver and the auto memory thermometer were set on each handle, ran along the north and south course of central urban area. We discussed and modified the method of time correction to evaluate a time change of temperature on 100-meter mesh area of which air temperature was observed at different time. Our method might be predominance than usual methods from the viewpoints of practicality and accuracy, especially in the limited situation of device and period of research.
