What Controls the Arctic Lower Stratosphere Temperature?
— Stratospheric temperature determines springtime ozone loss. This talk demonstrates for the first time how lower atmospheric weather and climate can change the temperature of the polar stratospheric regions. Paul Newman will present the results of his findings on Saturday, December 16 at 4:20 p.m. in Room MC 125. Measurements and Predictions of Atmospheric Influences from the Very Large July 14-16, 2000, Solar Proton Event — A large solar flare with an associated coronal mass ejection occurred in mid-July and caused a very large solar proton event at the earth between July 14-16, 2000. So far this is the largest solar storm of solar cycle 23. The solar proton fluxes were measured by instruments aboard the GOES-10 satellite and used in our proton energy deposition model to help quantify the energy input to the middle atmosphere during this large solar event. The measured and modeled impacts of this solar event will be compared and discussed in this paper. Charles Jackman will present
