E-book NOAA-N
The system consists of a pair of satellites, which ensures that every part of the Earth is regularly observed at least twice every 12 hours. The satellites provide global coverage of numerous atmospheric and surface parameters, furnishing quantitative measurements for input to global atmospheric and surface forecast models. As users around the world have learned how to exploit this quantitative radiometric satellite data routinely, the consistency and accuracy of predictions of potentially catastrophic environmental events have improved significantly. Better prediction of these events allows emergency managers to activate plans to reduce their effect and protect life and property. In addition, this continuous overlapping source of satellite data has provided the foundation for extensive climate and research programs. In many developing countries and over much of the oceans, satellite data is the only source of quantitative information on the state of the atmosphere and of the Earth’s surface, and is an invaluable source of real-time information about severe weather, critical for safety in these remote areas.
