The Interpolation and Homogenization of Long-Term Temperature Time Series at Baoding Observation Station in Hebei Province
摘要
Abstract
Using multi-source of monthly temperature data on the basis of preliminary integration and quality control, monthly mean temperature, maximum temperature, and minimum temperature time series covering 1913-2014 at Baoding station in Hebei province were interpolated by both two approaches of standardized method and multivariate linear regression. The interpolation results were analyzed by cross validation. The standardized method is more suitable for temperature data at Baoding, and the climate statistics characteristics from that are more consistent with those from surrounding stations in the same area. So the interpolated time series were homogenized by the penalized maximalF test (PMF), and results indicate that those monthly hundred-year temperature data are relatively continuous, only two breakpoints have been detected in mean minimum temperature series, which are caused by instrument replacement and station relocation, respectively, and then adjusted by Quantile-Matching (QM). Accordingly, the monthly hundred-year temperature time series at Baoding station were constructed. Moreover, the time series here were compared with the others at Beijing and Tianjin, and regional series in eastern and central China from some aspects of trend change and correlation analysis. The results show that the correlation coefifcients of monthly mean temperature between Baoding and adjacent single station almost reached more than 0.8, and the warming amplitude of trends for annual mean hundred-year temperature at Baoding and regional series in eastern and central China were nearly in the same order of magnitude, with 0.121℃/10a and 0.204℃/10a, respectively. Therefore, the data we have developed in this paper are relatively logical and errorless, to a certain extent.关键词
