HadCRUT (Hadley Centre Climate Research Unit)

HadCRUT (Hadley Centre Climate Research Unit) is a scientific dataset that tracks global surface temperature changes over time. It combines temperature measurements from land stations and sea surface readings to provide an accurate picture of how Earth's climate is warming or cooling. Developed by climate scientists in the UK, HadCRUT helps researchers analyze long-term climate patterns, identify trends, and understand the impacts of human activities on global temperatures. It is widely used for climate monitoring, policy making, and assessing climate change progress.
