The mass density of Earth's thermosphere (∼ 90–600 km altitude) is a critical parameter for
low Earth orbit prediction because of the atmospheric drag on satellites in this region. In this …

Abstract The Extreme Ultraviolet (EUV) monitor is an instrument on the NASA Mars
Atmosphere and Volatile EvolutioN (MAVEN) mission, designed to measure the variability of …

This paper describes the recommended solar forcing dataset for CMIP6 and highlights
changes with respect to CMIP5. The solar forcing is provided for radiative properties, namely …

We discuss, in a limited way, some of the challenges to advancing our understanding and
description of the coupled plasma and neutral gas that make up the ionosphere and …

The MgII index is an important proxy for solar activity; in particular it correlates well with the
EUV which is important for understanding the upper atmosphere. We compare the …

More than 2 decades ago, DJ Strickland and colleagues proposed use of the O/N2 column
number density ratio as a new geophysical quantity to interpret thermospheric processes …

We report the results of a comprehensive reanalysis of Ulysses observations of interstellar
He atoms flowing through the solar system, the goal being to reassess the interstellar He …

In February 2009, the commercial communications satellite Iridium 33 collided with the
Russian military communications satellite Cosmos 2251. The collision, which was not the …

The goal of the working group on cross-calibration of past and present ultraviolet (UV)
datasets of the International Space Science Institute (ISSI) in Bern, Switzerland was to …

A new general linear model of the climatology of the ionosphere's total electron content
(TEC) is described, accounting simultaneously for the influences of solar and geomagnetic …
