HAO Research Highlights

Monthly mean, globally integrated total gravity wave flux of energy
May 31, 2017

Most of the large events affecting the thermosphere and ionosphere part of the space environment come from the Sun, the solar wind, and Earth’s magnetosphere.

Stokes profiles of the Fe I transition
May 9, 2017

We investigate atomic transitions that have previously been identified as having zero polarization from the Zeeman effect. Our goal is to identify spectral lines that can be used for the calibration of instrumental polarization of large astronomical and solar telescopes, such as the Daniel K.

Coronal pseudostreamer magnetic topology
May 1, 2017

Magnetic fields in the sun's outer atmosphere, the corona, control both solar-wind acceleration and the dynamics of solar eruptions.

 Synthetic ultraviolet global images
April 27, 2017

The Global Airglow (GLOW) model has been updated and extended to calculate ultraviolet light emitted by the upper atmosphere, including during the day, the night, and in the aurora.

Variation of NmF2 log 10 [1/cm3] for different seasons
April 26, 2017

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.
