N2 - The Ground Surface Temperature (GST) history of the past several hundred years can be estimated from temperature profiles measured in boreholes. We applied this method to the Bangkok city and the surrounding area to investigate the thermal environment evolution due to urbanization. We measured temperature profiles in groundwater monitoring wells at 42 stations in 2004 and 2006. Inversion analysis of selected profiles at eight stations was conducted to reconstruct GST histories of the last 300 years assuming a horizontally layered structure. All of the estimated GST histories exhibit surface warming in the last century. The amount of temperature increase varies by site from 0.2 to 2.0 K and is greater in the city than in suburban and rural areas. This tendency may correspond to the history of urbanization in the Bangkok metropolitan area.
