Global Precipitation Climatology Project (GPCP) Climate Data Record (CDR), Version 1.3 (Daily)

The GPCP Daily analysis is a companion to the GPCP Monthly analysis, and provides globally complete precipitation estimates at a spatial resolution of one degree latitude-longitude and daily time scale from October 1996 to the present. Although derived using both some of the same, but also different, data sets and methods than used in the GPCP Monthly analysis, the GPCP Daily "adds up" to the GPCP Monthly. The GPCP Daily V1.3 analysis is currently computed by the University of Maryland and submitted to NCEI. The routine update of the product takes place two months after the end of the month, once all input data sets become available. The data set is part of World Climate Research Program (WCRP) and GEWEX activities, being part of the array of data sets describing the water and energy cycles of the planet under the auspices of the GEWEX Data and Assessment Panel (GDAP). Details of input data sets and methods can be found in: Huffman, G.J., R.F. Adler, M. Morrissey, D.T. Bolvin, S. Curtis, R. Joyce, B McGavock, J. Susskind, 2001: Global Precipitation at One-Degree Daily Resolution from Multi-Satellite Observations. J. Hydrometeor., 2(1), 36-50.

GPCP每日分析（GPCP Daily analysis）是GPCP月度分析（GPCP Monthly analysis）的配套数据集，可提供1996年10月至今、空间分辨率为1度经纬度的全球完整逐日降水估算产品。尽管其所用数据集与方法与GPCP月度分析既有重合之处，亦存在差异，但GPCP每日分析的累计结果可与GPCP月度分析结果相匹配。当前的GPCP每日分析V1.3版本由马里兰大学（University of Maryland）计算完成，并提交至美国国家环境信息中心（National Centers for Environmental Information, NCEI）。该产品的常规更新于每月结束后两个月开展，待所有输入数据集均已齐备后执行。本数据集隶属于世界气候研究计划（World Climate Research Programme, WCRP）与全球能量与水循环实验（Global Energy and Water Exchanges, GEWEX）相关活动，是在全球能量与水循环实验数据与评估小组（GEWEX Data and Assessment Panel, GDAP）统筹下，用于描述全球水与能量循环的数据集阵列的组成部分。输入数据集与研究方法的详细信息可参阅如下文献：Huffman, G.J.、R.F.
