Climate Data Records

Climate Data Records (CDRs) are carefully preserved and reliable collections of climate information gathered over long periods. They include measurements like temperature, rainfall, and atmospheric composition, collected from satellites, weather stations, and other sources. CDRs are created through rigorous processing to ensure accuracy and consistency over time, enabling scientists to analyze long-term climate trends and changes. Essentially, they serve as a detailed, trustworthy history of Earth's climate, helping us understand shifts, predict future conditions, and inform policy decisions related to climate change.
