一套新的30年全球台站逐日降水资料集:质量控制和评估
A Gauge-Based Global Daily Precipitation Dataset from 1980 to 2009:Quality Control and Evaluation
摘要
Abstract
A serial of quality control (QC) procedures were performed on a gauge-based global daily precipitation dataset from the Global Telecommunication System (GTS) for the period 1998-2009. A new global precipitation dataset was constructed after the control procedures. The new dataset was evaluated using CMAP and GPCP precipitation products. The results show that the frequency and spatial distribution of monthly precipitation in the new dataset well agree with those in CMAP and GPCP. The global mean correlation coefficient between gauge precipitation and CMAP/GPCP precipitation increased from 0.24 before QC to 0.70 after QC, accordingly, and the root mean square error decreased form 12 mm/d to 1 mm/d. The interannual variability of monthly precipitation in the new dataset is consistent with that of the CMAP/GPCP in Asia; and the seasonal variability of precipitation in different regions over the world coincides with those of CMAP/GPCP quite well.关键词
