The EUV Imager on Lagrange

Matthew West

(SwRI)

The Lagrange eUv Coronal Imager (LUCI) was a solar imager in the Extreme UltraViolet (EUV) being developed as a prototype for the European Space Agency (ESA) Vigil mission, a mission designed to be positioned at the...

Gravity waves and traveling ionospheric disturbances in the stratosphere, mesosphere and thermosphere from mountain waves, the polar vortex, the Tonga eruption and deep convection via multi-step vertical coupling

Sharon Vadas

(NWRA)

Atmospheric gravity waves (GWs) are created in the troposphere from wind flow over mountains, and in the stratosphere below the maximum of the polar vortex from imbalance of the polar vortex. Because these GWs are slow,...

Past Science Seminars

Can the tail wag the dog? The influence of micro-instabilities on collisionless plasma shocks.

Vadim Roytershteyn

(Space Science Institute)

Collisionless shocks are ubiquitous and hugely important in space and astrophysical plasmas. In hot and rarified (weakly collisional) plasma, the energy dissipation necessary for such a shock to exist must be provided by kinetic processes, among...

The influence of 3D cloud radiative effects on Orbiting Carbon Observatory measurements of CO2

Steven Massie

(LASP, University of Colorado)

The Orbiting Carbon Observatory (OCO-2) makes global measurements of CO2. This seminar reviews how the OCO-2 experiment retrieves CO2, and discusses physics (due to 3D cloud radiative effects) which is not included in the operational retrieval....

New Insights into Particle Acceleration at Shocks from Parker Solar Probe

Joe Giacalone

(University of Arizona)

I will discuss recent insights into the physics of particle acceleration based on spacecraft observations of shocks associated with fast coronal mass ejections (CMEs). The acceleration of charged particles to high energies is a fundamental topic...

Characteristics of Multi-Scale Current Sheets in the Solar Wind at 1 AU Associated with Magnetic Reconnection

Stefan Eriksson

(LASP)

The solar wind is a turbulent plasma regime that supports current sheets of many spatial scales. The vast majority of current sheets are narrower than 400 km. We associate these kinetic-scale current sheets with solar wind...

Modeling the Martian Atmosphere: The Planetary Climate Model and Mars Climate Database version 6

Antoine Bierjon

(LATMOS)

The last decade saw multiple in-situ and spacecraft missions scrutinizing the Martian weather and climate, from the near-surface to the exosphere. Numerical modeling remains a critical tool to tie together the various discoveries and insights gained...
