Center for Hydrologic Remote Sensing (CHRS)

CHRS数据门户是由加州大学欧文分校水文遥感中心(CHRS)运营的卫星降水数据平台。该平台提供基于PERSIANN算法的全球降水估算数据，覆盖60°S至60°N区域，时间跨度从2000年3月至今，分辨率0.25°×0.25°。数据产品包括小时、3小时、6小时、日、月和年尺度数据，可通过HTTP和FTP下载，近实时更新，延迟约2天。The CHRS Data Portal is a satellite precipitation data platform operated by the Center for Hydrometeorology and Remote Sensing (CHRS) at the University of California, Irvine. This platform provides global precipitation estimation data based on the PERSIANN algorithm, covering the region from 60°S to 60°N, spanning from March 2000 to the present, with a spatial resolution of 0.25°×0.25°. The data products include datasets at hourly, 3-hourly, 6-hourly, daily, monthly and annual temporal scales. The data is available for download via HTTP and FTP, with near-real-time updates and a latency of approximately 2 days.
