Monday, January 28, 2019

Using Fabry-Perot interferometers (FPI) at five mid-latitude stations (Boulder, Palmer, Millstone Hill, Mt. John, and Kelan) in both hemispheres, we examine the inter-hemispheric and seasonal variations of mid-latitude thermospheric dynamics.

HiWind has launched and landed!!

HiWIND team, Kiruna, Sweden

Finally, after repeated postponements due to unfavorable weather conditions, HiWind launched from Esrange Space Center, Kiruna, Sweden, on Sunday, June 24. The HiWIND team arrived in early May 2018.
