p implies q is true if p is false or q is true.

Dr PlasmaNerd 🌏 🛰️ Julie Brett Carter Radio Occultation (RO) is the process of a (radio) signal changing as it passes through the atmosphere. It is used a lot in the met community, but in our case we care about the refraction of the signal caused by the ionosphere (the signal is 'occulted').

Dr PlasmaNerd 🌏 🛰️ Julie Brett Carter It gives us measurements of the 'total electron content' (TEC) in the ionosphere, which is the most abundant data we have of the ionosphere. We need for our data assimilation models. Attached shows the TEC from a 15 minute period using ground based receivers.

Gotta love a good stats comic. Right ~Hedge~?

Reconstructing scene depth from video with moving subjects can be very challenging. Now there’s a #DeepLearning approach that generates accurate 3D depth maps from ordinary video, even when both camera and subjects are in motion. Learn more at → goo.gle/2HxYqCm

Signals between satellites and the ground — like GPS — can be disrupted by hard-to-predict bubbles in Earth's upper atmosphere. These twin satellites will help us study when and how these bubbles can appear and scramble signals. Meet E-TBEx: go.nasa.gov/2WpVkEV

If a linear ODE has complex eigenvalues, solutions oscillate. If real parts are negative, oscillations decay exponentially.

Monica highlights the need to adopt a modern scientific workflow (e.g. open source (The SunPy Project ;)) reproducibility etc) as the next steps forward in using #ML for solar flare predictions #mlhelio19 ML-Helio

We all have used satellite navigation: but have you ever seen the satellites in the sky? On Nov 6, I imaged representative Navigation satellites from four constellations: NAVSTAR 73 (GPS); GALILEO 21; BEIDOU 3M7; and KOSMOS 2501 (GLONASS).
