The purpose of this talk is to shed light into PRL editorial process and policy and address the many questions frequently raised by the thousands of active authors, referees and readers. How do the editors determine which papers to publish in PRL? What how-tos should you know as an author and a referee? Why should you submit your work to us? How are journals in general and PRL in particular reorienting amid increasing competition and other challenges? I plan to address these and related issues during my presentation and the subsequent discussion.</div>http://www.chalmers.se/en/departments/rss/calendar/Pages/A-3D-model-for-O2-airglow-perturbations-induced-by-gravity-waves-in-the-upper-mesosphere.aspxhttp://www.chalmers.se/en/departments/rss/calendar/Pages/A-3D-model-for-O2-airglow-perturbations-induced-by-gravity-waves-in-the-upper-mesosphere.aspxA 3D model for O2 airglow perturbations induced by gravity waves in the upper mesosphere<p>Sektionsgemensamt sammanträdesrum (EDIT-room 3364)</p><p>​Subtitle: A forward model for the new Swedish satellite MATS Anqi Li is a master thesis student at the Department of Earth and Space Sciences, Chalmers and Department of Meteorology, Stockholm University</p>​<strong><br />Abstract:</strong><br />To investigate the influence of atmospheric waves in the mesosphere, a new Swedish<br />satellite MATS (Mesospheric Airglow/Aerosol Tomography and Spectroscopy) will<br />be launched in 2019. It will observe infrared emissions at 762 nm from the O2(b1Σ+g )<br />airglow in the region of 70 − 110 km altitude. As a part of the design work for the<br />MATS project, an accurate forward model is needed to estimate what MATS is expected<br />to measure. The results from this model will be used to evaluate the retrieval<br />methods for processing the measurements from MATS.<br />In this thesis project, a gravity wave model and a photochemistry model were coupled<br />to simulate both the day- and nightglow emission fields in three spatial dimensions<br />and time. Simulated satellite images were generated taking into consideration<br />the sphericity of the Earth and the limb-viewing geometry of MATS. Simulation<br />parameters were set according to the preliminary design of the instrument, such as<br />the satellite orbit, image resolution and spectral selections. These satellite images<br />were the first simulated airglow limb images made for the MATS project.<br />By analysing the output data, the relations between wave parameters and airglow<br />perturbations were investigated. It was shown that wave patterns can be easily<br />observed between 88 − 105 km due to the relatively large perturbation in airglow<br />emissions. The O2 airglow emission field was found to be highly sensitive to atomic<br />oxygen concentration field as an input. Furthermore, as expected, wave patterns<br />projected on simulated satellite images largely depend on the horizontal orientation<br />of the wave propagation. This implies that a tomographic reconstruction is needed<br />when the angle between the wave front and the limb-viewing direction is large.<br />Finally, limitations of the model were discussed.<br />Keywords: MATS, internal gravity wave, mesosphere, O2 airglow.http://www.chalmers.se/en/departments/rss/calendar/Pages/Pamel.aspxhttp://www.chalmers.se/en/departments/rss/calendar/Pages/Pamel.aspxPamela Klaassen, Royal Observatory, Edinburgh<p></p><p>​Title: TBA</p>​Abstract: TBAhttp://www.chalmers.se/en/departments/rss/calendar/Pages/Anna-Neubeck,-Stockholm-University.aspxhttp://www.chalmers.se/en/departments/rss/calendar/Pages/Anna-Neubeck,-Stockholm-University.aspxAnna Neubeck, Stockholm University<p>Seminar room, Onsala Space Observatory</p><p>​Title: TBA</p>​Abstract: TBAhttp://www.chalmers.se/en/departments/rss/calendar/Pages/Erik-Blomberg,-Earth-and-Space-Sciences.aspxhttp://www.chalmers.se/en/departments/rss/calendar/Pages/Erik-Blomberg,-Earth-and-Space-Sciences.aspxErik Blomberg, Earth and Space Sciences<p>EA</p><p>​​Title: Biomass Retrieval in Topographic Boreal Forest using Polarimetric and Tomographic SAR in P- and L-band</p><span>Erik Blomberg is a PhD student in the Radar Remote Sensing research group in the Department of Earth and Space Sciences.<span style="display:inline-block"></span></span>http://www.chalmers.se/en/departments/rss/calendar/Pages/Mitra-Hajigholi,-Chalmers,-Earth-and-Space-Sciences.aspxhttp://www.chalmers.se/en/departments/rss/calendar/Pages/Mitra-Hajigholi,-Chalmers,-Earth-and-Space-Sciences.aspxMitra Hajigholi, Chalmers, Earth and Space Sciences<p>Seminar room, Onsala Space Observatory</p><p>​Title: TBA​</p>​Abstract: TBAhttp://www.chalmers.se/en/departments/rss/calendar/Pages/Daniel-Tegnered,-Earth-and-Space-Sciences.aspxhttp://www.chalmers.se/en/departments/rss/calendar/Pages/Daniel-Tegnered,-Earth-and-Space-Sciences.aspxDaniel Tegnered, Earth and Space Sciences<p>EA</p><p>​Daniel Tegnered is a PhD student in the Plasma Physics and Fusion Energy research group in the Department of Earth and Space Sciences.</p>​Title: TBAhttp://www.chalmers.se/en/departments/rss/calendar/Pages/Seminar-by-Nils-Ryde,-Lund-Observatory.aspxhttp://www.chalmers.se/en/departments/rss/calendar/Pages/Seminar-by-Nils-Ryde,-Lund-Observatory.aspxNils Ryde, Lund Observatory<p>Seminar room, Onsala Space Observatory</p><p>​Title​: TBA</p>​​Abstract: TBA​http://www.chalmers.se/en/departments/rss/calendar/Pages/Kristin-Larson,-University-of-Colorado.aspxhttp://www.chalmers.se/en/departments/rss/calendar/Pages/Kristin-Larson,-University-of-Colorado.aspxGPS Can't Do That, Can It?<p>Seminar room, Onsala Space Observatory</p><p>Kristin Larson, University of Colorado</p><div><br /></div> <div>How building a GPS seismometer led to the development of GPS snow, soil moisture, vegetation and water level sensors​.<br /><br /></div> http://www.chalmers.se/en/departments/rss/calendar/Pages/-The-23rd-EVGA-2017.aspxhttp://www.chalmers.se/en/departments/rss/calendar/Pages/-The-23rd-EVGA-2017.aspxThe 23rd EVGA, 2017<p></p><p>​The 23rd Working Meeting of the European VLBI Group for Geodesy and Astrometry (EVGA) will be organised at Chalmers University of Technology in Gothenburg 15 -
