How Changes in Earth's Magnetic Field and Ionosphere Affect Us - Part 4
Part 4 in a discussion on How do changes in Earth's magnetic field and ionosphere affect us? Anya Strømme – EISCAT/SRI International. She’s working with very high power radar to study the aurora borealis which are better observed at higher latitudes. She’s studying particles coming into the atmosphere, heating it, generating currents—this is where our satellites fly…this impacts tv reception, GPS, cell phones in a much more dramatic way than we can imagine. Run time 03:16.
How do changes in Earth's magnetic field and ionosphere affect us?
Part 1 in a discussion on How do changes in Earth's magnetic field and ionosphere affect us? Bob McCoy – Office of Naval Research. Storms and variations in the ionosphere impact Navy instruments, e.g, Suns storms (disturbances) can degrade GPS affecting ship navigation, airplanes, and all kinds of communication and transportation on Earth. Dish TV and satellite operations are also disrupted or impacted by this. Talks about the fun of flying rockets and studying the data to make new discoveries
How do changes in Earth's magnetic field and ionosphere affect us? - Part 2
Part 2 in a discussion on How do changes in Earth's magnetic field and ionosphere affect us? Gang Lu – National Center for Atmosphere Research. Talks about her data analysis of radar and satellite data. Talks about the continuing exploration of all that is to be investigated in exploring the fine particle changes in the aurora. Run time 03:38.
How do changes in Earth's magnetic field and ionosphere affect us? - Part 3
Part 3 in a discussion on How do changes in Earth's magnetic field and ionosphere affect us? Kyle Johnson – University of Colorado. Talks about meteor entry into the atmosphere (large flaming balls and little pieces of sand) leaving a trail visible on radar. They use the meteor trails to model affects on the lower atmosphere. Our daily lives depend on the Sun so it’s important in understanding the nature of that energy balance; it’s not a direct connection, but its all connected. He had al
