This temperature data is taken from land-based thermometers, ocean buoys, ships, and satellites. These measurements are transmitted to weather stations and climate centers around the globe where they are processed, averaged, and analyzed in order to monitor the trends and create climate models.

Although not all regions have mountains, elevated areas exhibit distinct temperature variations.

• Sun Exposure: Sunlit slopes tend to be warmer, while shaded areas remain cooler.
• Altitude Effects: Temperatures drop by approximately 6°C for every 1,000 meters of elevation, creating distinct microclimates.
