Estimation of the temporal and spatial variation of surfacetemperature distribution in the Korean peninsula usingNOAA/AVHRR data

摘要

The surface temperature variation of the Korean peninsular was estimated using split-window methodrnand NOAA/AVHRR data in 1991, 1995 and 2000. To analyze the characteristics of the urban surface temperature,rnthe differences in surface temperature between day and night time were computed and analyzed for the comparison.rnThe differences of surface temperature in seasonal variations and yearly fluctuations in big cities were lower thanrnthose in rural regions. The quantified result of Korean peninsula for last ten years (1991-2000) showed the differencesrnof surface temperature clearly due to the urbanization. The ranges of difference were 3-15℃ around the Koreanrnpeninsula. The small difference of the surface temperature and the continuously increasing temperature in urbanrnarea are expected due to the effect of increased pavement, the loss of greenery resources and the unwise developmentrnof urban area.
