Monitoring urban heat environment using MODIS data for main cities in East Asia



Conclusion
In this study, the land surface temperature was calculated using thermal band with 500m resolution TERRA MODIS data in combination with the visible band data of 250m resolution for 5 major cites in East Asia, and a methodology to indicate the heat flux of urban area to estimate of the heat island phenomenon from the satellite images under the different geographic, climatic conditions. The method enables the comparison of heat flux for the 5 cites using the MODIS data.

Continuous observation will be made for more quantative analysis in terms of heat flux as well as the vegetation function to reduce the heat island phenomenon, using long term satellite information which avoid the temporal error such as local climatic condition including the whether of the observation day and time, and sensor anomalies. Furthermore, some more cities from South East Asia such as Bangkok, Hanoi, Hochimin city, Jakarta, Kuala Lumpur, Singapore, covered by Bangkok broadcasting station will be added for the study.
