摘要
The World Meteorological Organization (WMO) Commission for Climatology (CCl)/CLIVAR/JCOMM Expert Team on Climate Change Detection and Indices (ETCCDI) held a number of regional workshops whose data were used to help create HadEX, the first global land-based, gridded dataset of temperature and precipitation extremes. Experts from ETCCDI developed a new dataset to address the issues of HadEX, using the world's largest repository of daily in situ observations of temperature and precipitation. The resulting dataset was known as GHCNDEX, which was an operationally updated, global land gridded dataset of climate extremes. The experts also demonstrated the application of the dataset for climate change and climate monitoring purposes in addition to assessing some issues regarding uncertainty by comparing the results with existing datasets.
