Climate Indices for heat waves, droughts and floods in Sweden (1922-2021)

Includes netCDF files for the following climate indices:Standardized Precipitation Index (SPI) - 3, 6 and 12-month accumulation periods, monthly frequencyStandardized Precipitation and Evapotranspiration Index (SPEI) - 3, 6 and 12-month accumulation periods, monthly frequencyDaily Flood Index (DFI), daily frequencyHeat Wave Intensity Index (HWI) - based on European Drought Observatory and Sveriges meteorologiska och hydrologiska institut definitions, daily frequency.<br>The indices were calculated based measured daily temperatures and precipitation rates available on the SMHI Open API for meteorological observations. The data is interpolated in a 100x100 grid in WGS84 coordinate system.<br>

本数据集包含以下气候指数的netCDF（netCDF）文件：
标准化降水指数（Standardized Precipitation Index, SPI）：涵盖3、6、12个月累积周期，数据频次为月度；
标准化降水蒸散指数（Standardized Precipitation and Evapotranspiration Index, SPEI）：涵盖3、6、12个月累积周期，数据频次为月度；
每日洪水指数（Daily Flood Index, DFI）：数据频次为每日；
热浪强度指数（Heat Wave Intensity Index, HWI）：依据欧洲干旱观测站（European Drought Observatory）与瑞典气象水文研究所（Sveriges meteorologiska och hydrologiska institut, SMHI）的定义编制，数据频次为每日。
上述指数基于瑞典气象水文研究所（SMHI）开放气象观测API提供的实测日气温与降水速率数据计算得到。数据采用WGS84坐标系进行插值，生成100×100的网格数据集。
