Environment - Water physical stock by region 1995–2020

The water physical stock accounts present information on the hydrological cycle based on the System of Environmental-Economic Accounts (SEEA).
The water physical stock accounts focus on water quantity and provide estimates of national and regional water flows (precipitation, evapotranspiration, and rivers) and change in storage (ice, snow, soil moisture, groundwater, lakes and reservoirs, and hydro-electric generation water use)analyse seasonal patterns, and any changes in seasonality analyse extreme events which may be obscured in annual data compare water statistics with other quarterly data, such as agricultural output or electricity generation

水资源物理存量账户基于环境经济账户体系（SEEA）提供了关于水循环的信息。该账户专注于水量，并提供了关于国家及地区水流量（降水、蒸散和河流）以及储水变化（冰川、积雪、土壤湿度、地下水、湖泊和水库以及水电用水）的估算。分析季节性模式，并探讨季节性变化；分析年度数据中可能被掩盖的极端事件；将水文学统计数据与其他季度数据进行比较，如农业产出或电力生成数据。
