Ozone Over Time

One mission of NOAA’s Global Monitoring Laboratory is to monitor the amount of ozone in the stratosphere. Every year in October there is a dramatic decrease of ozone over the South Pole. This is called the Ozone Hole. Today you will look at ozone data from a Dobson Ozone Spectrometer. NOAA has Dobson instruments at many locations around the world. You will be looking at data from the Dobson located at the South Pole.

Space Weather Impacts: GPS

GPS has changed society. Multiple applications: oil drilling, aviation, precision agriculture, surveying, military operations, emergency response, recreational, and so much more depend on the continuous availability of this vital satellite navigation system. These critical applications rely not only on navigational services provided by GPS, but high accuracy timing as well. Space weather storms can interfere with the high accuracy and availability of GPS leading to erroneous information or even complete loss of GPS capabilities. NOAA’s Space Weather Prediction Center provides critical information on potential interference to GPS applications to end-users around the world.

Space Weather Impacts: Communications

Effective communication can mean the difference between life and death. There are many different types of technology that contribute to various forms of communication. Some of these technologies can experience significant degradation due to space weather storms. End-users, such as the aviation and emergency response communities can encounter significant impacts on the critical communication assets they depend on. NOAA space weather forecasters provide alerts and warnings to ensure key situational awareness when systems are being impacted, and help operators determine alternatives during space weather disturbances.
