    Abstract: Based on the daily meteorological data from 1956 to 2011 in Northwest (NW) China and the Penman-Monteith (PM) equation, the regional reference crop evapotranspiration (ET0) is estimated. The ET0 variations in time series and spatial distributions are analyzed. The trend analysis, Mann-Kendall (M-K) test, wavelet analysis, stepwise regression and EO... Show More

    Abstract: Distances between permanent GNSSS stations in positional systems are usually short between 30 km and 80 km. So calculated distances between the GNSS stations from their position coordinates calculated by processing collected GNSS data with Bernese software will be very well determined. The first time we determined that two days before earthquake in... Show More
