GPCC Monitoring Product Version 5.0 at 1.0°: Near Real-Time Monthly Land-Surface Precipitation from Rain-Gauges based on SYNOP and CLIMAT Data

This is the GPCC Monitoring Product of monthly global land-surface precipitation based on the station database (SYNOP, CLIMAT) available via the Global Telecommunication System (GTS) of the World Meteorological Organization (WMO) at the time of analysis (2 months after end of an analysis month). This product contains the monthly totals on a regular latitude/longitude grid with a spatial resolution of 1.0° x 1.0° latitude by longitude. Interpolation is made on the anomalies from the GPCC Climatology V2015 in the corresponding resolution (DOI: 10.5676/DWD_GPCC/CLIM_M_V2015_100). The temporal coverage of the dataset ranges from January 1982 until the month for which GTS data (SYNOP and CLIMAT) is available, i.e. 2 months after end of the analysis month due. The GPCC Monitoring Product is the in situ component to the satellite-gauge combined precipitation analyses of the Global Precipitation Climatology Product (GPCP) and the CPC Merged Analysis of Precipitation (CMAP). Moreover it supports regional climate monitoring and serves the land-surface complement to the Hamburg Ocean-Atmosphere Parameters and Fluxes from Satellite (HOAPS) data set. This GPCC product is recommended to be used for applications requesting high quality gridded monthly precipitation analyses in near real-time. GPCC Monitoring Product (GPCC_MP) users should carefully take into account the number of stations available for a specific analysis grid in a specific month.

本数据集为全球降水气候学中心（GPCC）监测产品，基于分析时段（即分析月份结束后2个月）可通过世界气象组织（WMO）全球电信系统（GTS）获取的地面站数据库（SYNOP、CLIMAT）构建，用于生成逐月全球陆地表面降水数据。该产品以规则经纬网格形式存储逐月降水总量，空间分辨率为1.0°×1.0°经纬度。数据插值基于对应分辨率下的GPCC气候学V2015版本的距平场完成（DOI：10.5676/DWD_GPCC/CLIM_M_V2015_100）。本数据集的时间覆盖范围为1982年1月至可获取GTS（SYNOP与CLIMAT）数据的最新月份，即常规分析月份结束后2个月的时段。全球降水气候学中心监测产品是全球降水气候学产品（GPCP）与美国气候预测中心合并降水分析（CMAP）所采用的卫星-地面站联合降水分析中的地面观测组分。此外，该产品可支撑区域气候监测，并作为基于卫星的汉堡海洋-大气参数与通量数据集（HOAPS）的陆地表面补充数据。该GPCC产品推荐用于需近实时高质量格点化逐月降水分析的应用场景。全球降水气候学中心监测产品（GPCC_MP）的使用者需谨慎考量特定月份下特定分析网格可获取的地面站数量。
