Observations from lidars and satellites have shown that large temperature increases and decreases occur in the middle and low latitudes of the mesosphere and lower thermosphere (MLT) region during geomagnetic storms.

Medium-scale ionospheric ionization structures are a persistent global feature of the earth’s ionosphere.

The McIntosh Archive consists of a set of hand-drawn solar Carrington maps created by Patrick McIntosh from 1964 to 2009. McIntosh used mainly H, He-I 10830Å and photospheric magnetic measurements from both ground-based and NASA satellite observations.

The high-resolution thermosphere-ionosphere-electrodynamics general circulation model (TIEGCM) was used to investigate the cause of F2-region electron density (Ne) responses to the Great American Solar Eclipse on 21 August 2017 at Millstone Hill (42.610N, 71.480W).

Jenna Samra and Philip Judge identify two new emission features observed during the 21st August 2017 total solar eclipse by a novel spectrometer, AIR-Spec, flown at 14.3 km altitude aboard the NCAR Gulfstream V aircraft.

A specialized satellite version of the passive microwave electric field retrieval algorithm (Peterson et al., 2015) is applied to observations from the Tropical Rainfall Measuring Mission (TRMM) and Global Precipitation Measurement (GPM) satellites to estimate the generator current for the Global

The NASA Ionospheric Connection explorer (ICON) will study the coupling between the thermosphere and ionosphere at low- and mid-latitudes by measuring the key parameters.
