Precipitation monthly and daily gridded data from 1979 to present derived from satellite measurements

The analysis of the Global Precipitation Climatology Project (GPCP) provides global estimates of precipitation as monthly means since 1979 (GPCP monthly v2.3) and as daily means since 1996 (GPCP daily v1.3), based on estimates using microwave imagers on polar-orbiting satellites and infrared imagers on geostationary satellites. The monthly product also includes information from rain-gauge observations analyzed by the Global Precipitation Climatology Centre (GPCC). The GPCP daily product is tied to GPCC indirectly via its calibration with the GPCP monthly product.
Within the hydrological cycle, precipitation is the main component of water transport from the atmosphere to the Earth’s surface. Precipitation varies strongly, depending on geographical location, season, synopsis, and other meteorological factors. The supply with freshwater through precipitation is vital for many subsystems of the climate and the environment, but there are also hazards related to extensive precipitation or the lack of precipitation.

全球降水气候学项目（GPCP）的分析提供了自1979年以来的全球降水量估计值，以月平均量形式呈现（GPCP月度v2.3版），以及自1996年以来的日平均量（GPCP日度v1.3版），这些估计值基于利用极地轨道卫星上的微波成像仪和地球静止轨道卫星上的红外成像仪的估计数据。月度产品还包括由全球降水气候中心（GPCC）分析过的雨量计观测信息。GPCP日度产品通过与其月度产品的校准间接与GPCC相连。在水文循环中，降水是大气向地球表面传输水分的主要组成部分。降水在地理分布、季节、天气形势及其他气象因素等方面存在显著差异。通过降水提供淡水对于气候和环境的许多子系统至关重要，但过度降水或降水不足也带来了相关的风险。本数据集来源于GPCP：请参阅右侧的许可文本。
