Rainfall and temperature forecast and observations - verification 2016-05 to 2017-04

Historical rainfall and temperature forecast and observations hourly data (2016-05 to 2017-04), used to compare and verify forecasting. Observations data is from a sample of 518 automatic weather stations (AWS) over land, and is at the surface level. Data has been aggregated from one-minute readings into hourly values, for forecast comparison purposes. This observations data is partly QC'd.\r\n\r\nForecasted weather elements include temperature, maximum and minimum temperature, rainfall probabilities and rainfall amounts. Different forecast products have different time resolutions, e.g. temperature forecasts are made for each hour, while maximum and minimum temperature forecasts are made for each day.\r\n\r\nThis dataset is approximately 650 Mb in size.

本数据集涵盖2016年5月至2017年4月的逐小时历史降雨、气温预报与观测数据，用于预报效果的对比与验证。观测数据取自陆地区域518个自动气象站（Automatic Weather Stations, AWS）的采样样本，为地表层观测值。该数据已将每分钟原始观测值聚合为逐小时统计值，以适配预报对比需求，且此观测数据已完成部分质量控制（Quality Control, QC）流程。

预报气象要素包含气温、最高气温、最低气温、降雨概率及降雨量。不同预报产品的时间分辨率存在差异：例如气温预报为逐小时发布，而最高、最低气温预报为每日更新。

本数据集总容量约为650 Mb。
