Second Announcement: 20th International EISCAT Symposium, and 15th International LPMR Workshop (Layered Phenomena in the Mesopause Region) August 15-19, 2022 Meeting website: https://www.space.irfu.se/workshops/LPMR-EISCAT <https://www.space.irfu.se/workshops/LPMR-EISCAT> Dear Colleagues, the 15th International Workshop on Layered Phenomena in the Mesopause Region (LPMR) and the 20th International EISCAT Symposium will be held as a joint meeting in Sweden on August 15-19, 2022. The LPMR workshop aims at advancing our understanding of mesospheric ice clouds and related phenomena in the Earth’s mesosphere and lower thermosphere, ranging from microphysics to the global and solar-terrestrial processes controlling the region. The EISCAT Symposium has its focus on incoherent scatter radar and on the atmospheric/ionospheric science explored by this measurement method, including the upcoming EISCAT_3D system. A goal of the joint meeting is to bring the LPMR and EISCAT communities together, thus providing a forum to learn more about scientific interests, recent advances and new opportunities. The meeting will comprise both separate and combined LPMR and EISCAT sessions. The meeting will be held in Sundbyholm Castle at scenic Lake Mälaren, approximately 80 km west of Stockholm. Note that the EISCAT-related sessions will be held in a hybrid mode, thus also providing an option to participate online. For our planning, we very much would like you to submit a notification of interest already now. You can specify how probable your participation will be.
