2022-11-02 A dataset of hydroclimate variations during the past 1000 years for Eastern China doi:10.57760/sciencedb.06136 en The dataset was developed based on the dryness and wetness index at 63 sites, which was reconstructed from Chinese historical ducuments, used a five-grade category index ranging from 1 to 5 with 10%, 25%, 30%, 25%, and 10% frequency distributions, respectively, based on the May–September hydroclimatic description in the historical records. Among these categories, 1 indicates very dry conditions, revealed by long-lasting rainless conditions; 5 indicates very wet conditions, with heavy rainfall lasting several days, even up to one month, and many flooded counties; 3 indicates normal conditions, with few or no climatic disasters; and 2 and 4 are between extreme and normal, and indicate relatively dry and relatively wet conditions, respectively. Since previous of 1470, a large number of data were missing, we used spatial (Probit model) and temproal (Markov chain) interpolation methods.The datasest covered 9 regions as the north (NC), the northwest (NW), Guanzhong Plain (GP), Shandong Island (SI), Henan–Hubei (HH), the middle-lower reaches of the Yangtze River (MLRYR), the southwest (SW), the southeast (SE), and the south (SC), based on their geographic location. Spatially, the dataset covered the scope of 22-41°N, 102-122°E.The data file includes 10 colomns: Year, and 9 regions.
