The Precipitation - PERSIANN Climate Data Record (CDR) is a daily, quasi-global precipitation product that spans from 1982–present. Coverage extends from 60° S–60°N and 0°–360° longitude at 0.25° spatial resolution. This dataset supports climatologists, hydrologists, hydrometeorologists, and hydroclimatologists in various forms of climate research, including extreme event (flood and drought) analysis.
