摘　　要：The China Meteorological Administration(CMA)has recently developed a new global monthly homogenized land-surface air temperature data set.Based on this data set,we reanalyzed the change in global annual mean land-surface air temperature(LSAT)during three time periods(1901–2014,1979–2014 and 1998–2014).The results show that the linear trends of global annual mean LSAT were 0.104°C/decade,0.247°C/decade and 0.098°C/decade for the three periods,respectively.The trends were statistically significant except for the period 1998–2014,the period thatThe China Meteorological Administration （CMA） has recently developed a new global monthly homogenized land-surface air temperature data set. Based on this data set, we reanalyzed the change in global annual mean land-surface air temperature （LSAT） during three time periods （1901-2014, 1979-2014 and 1998- 2014）.
