AB: The Global Historical Climatology Network (GHCN) Daily dataset is designed to facilitate climate extremes research on the global scale. The dataset contains daily temperature and precipitation time series for over 15,000 stations worldwide, with about 10,000 extending back to 1950 and several thousand being updated daily. Both historical and real-time GHCN data undergo a suite of two dozen rigorous quality assurance reviews, including checks for spurious changes in the mean and variance and neighbor checks that identify outliers from both a serial and a spatial perspective. The quality assured dataset is freely available from NOAA's National Climatic Data Center (NCDC). GHCN-Daily has been employed in a variety of extremes-related assessment activities. For example, the dataset is used operationally by NCDC in monitoring climate extremes in North America and in tracking large-scale changes in observed daily maximum and minimum temperature across the globe. GHCN-Daily data have also been used to compute a variety of climate change indices that quantified observed changes in climate extremes as well as projected changes (e.g., in warm spells) simulated by the NOAA's Geophysical Fluid Dynamics Laboratory Climate Model 2.1.
