Temporal change and its spatial variety on land surface temperature and land use changes in the Red River Delta, Vietnam, using MODIS time-series imagery

摘要: Temporal changes in the land surface temper- ature (LST) urbanization areas are important for study- ing an urban heat island (UHI) and regional climate change. This study examined LST trends under dif- ferent use categories Red River Delta, Viet- nam, using Moderate Resolution Imaging Spectroradiometer (MODIS) product (MOD11A2) cover type (MCD12Q1) 11 years (2002-2012). Smoothened time-series MODIS data were reconstructed by Harmonic Analysis of Time Series (HANTS) algorithm. The (maximum minimum temperatures) was assessed hourly air temperature dataset two land- based meteorological stations provided National Climatic Data Center (NCDC). Significant correlation obtained between daytime (R 2 =0.73, root mean square error (RMSE)=1.66 °C) night time =0.84, RMSE= 1.79 °C). Statistical analysis also showed that vary strongly depending on type. Forest, wetland, cropland had a slight tendency to decline, whereas sharper increases. In urbanized areas, these increasing even more obvious. is undeniable evidence negative impact (SUHI) global warming.
