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

When
-

Abstract: 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 turbulence at 1 AU. The largest current sheet is 64,000 km wide on average, or 150 times wider than the more prevalent and turbulent ones.

ARM Value-added Products: A Community Resource for Atmospheric and Climate Model Research

When
-

Abstract: The Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) user facility provides continuous field measurements of atmospheric conditions by deploying state-of-the-art remote sensing and in situ atmospheric observatories at climatically significant locations.

Investigating the thermosphere-ionosphere system through Earth’s FUV emissions

When
-

Abstract: The Earth’s upper atmosphere emits in the Far-UV (120 to 200nm); images at these wavelengths are indicative of the changes in, and evolution of, the lower thermosphere and ionosphere — a region critical for communication and navigation signals.  Several missions are currently available (including GOLD and TIMED/GUVI) and are planned (InspireSat/OWLS) that take advantage of the characteristics of FUV emissions to examine the neutral composition, momentum transport of gravity waves, and connection to the ionosphe
