Study Notes
- First color images of Earth from space inspired the ecological movement, leading to satellite images becoming essential for survival.
- Satellites in space provide different views of Earth through visible, thermal infrared, and radar imaging, aiding in weather forecasting and agricultural monitoring.
- Altimetry measurements track sea level rise and ocean circulation patterns, providing crucial evidence of environmental changes.
- The European Copernicus program operates a fleet of spacecraft for monitoring Earth's changes and providing accurate data for sea level measurements.
- Professor Martikas and his team on the Greek island of Crete developed a unique calibration system for satellites, including a prototype mechanism called the transponder.
- The upgraded system on Crete now calibrates the new satellite Sentinel 6 Michael Freilich, dedicated to measuring sea level rise with improved resolution.
- Gavdos, a small island off Europe, was chosen as the site for the new transponder system due to its strategic location for satellite comparisons and calibration.
