Using sophisticated algorithms, they're able to process that data into environmental data records, such as cloud coverage and height. Every day, the CGS receives about 60GB worth of data from weather satellites. But what Raytheon does with that off-the-shelf hardware is impressive. The CGS doesn't have any custom hardware, Sullivan told me. The system covers "every meter of Earth in a 4 hour period," said Sullivan. It collects and processes all that data so that it can then be sent to the National Weather Service for forecasting. The CGS takes inputs not only from American weather satellites, but also from international partners. That's why Raytheon is also managing the JPSS Common Ground System (CGS). In addition to the money saved, more accurate evacuation zones means that emergency services are going where they need to.īut all that data gathered by weather satellites doesn't do much good without a way to process it. So by having a more accurate evacuation zone, money doesn't have to be spent to needless evacuate neighborhoods. According to Raytheon's Bill Sullivan, who's a program director for JPSS, every mile of shoreline evacuated results in a cost of about $1 million. The advances in sensor technology can't be understated - because of them, the ability for meteorologists to forecast the path of hurricanes and storms has improved substantially, allowing for better planning while reducing harms to both people and property. Other sensors provide better ozone concentration information, as well as microwave imaging of temperature and moisture information to complement the other sensors. The JPSS satellites will be able to capture images in infrared, which enables the satellites to capture different layers of clouds, moisture information at different parts of the atmosphere, and temperature information.
