Based on MASH-generated homogenized observation series of daily mean, maximum, and minimum temperatures and daily precipitation and wind speed from 88 national meteorological stations in Beijing-Tianjin-Hebei region (BTH) during 1960-2015, we calculate the linear trends and Morlet wavelets of the time series at each station to analyze the climate change in BTH. The results suggest that the MASH method can detect and adjust discontinuities in association with changes in the locations of stations, observation instruments and surrounding environs. The annual mean temperature over the region on average has risen by 0.26℃/10 a, precipitation has decreased by 11.3 mm/10 a, and wind speed has decreased by 0.19 m s^-1(10 a)^-1.
