Integrated Surface Data (ISD)

Integrated Surface Data (ISD) is a comprehensive collection of weather observations from thousands of stations worldwide, regularly reporting details like temperature, wind, precipitation, and air pressure. These data are collected multiple times each day and standardized, making them valuable for analyzing climate patterns, tracking weather changes, and supporting research. ISD helps scientists, meteorologists, and policymakers understand current conditions and long-term trends by providing reliable, consistent, and detailed surface weather information.
