NCAR High Altitude Observatory

About the Mauna Loa Solar Observatory

The Mauna Loa Solar Observatory (MLSO) occupies part of the NOAA Mauna Loa research site located on the flank of Mauna Loa at an elevation of 3440 meters on the island of Hawaii. It is operated by the High Altitude Observatory, a division of the National Center for Atmospheric Research, which is located in Boulder, Colorado.

Lower thermospheric material transport via Lagrangian coherent structures

Lagrangian coherent structures (LCSs) are indicating regions of material transport
Thursday, May 5, 2022

Lagrangian coherent structures (LCSs), indicating regions of material transport, are derived from models of the lower thermosphere for five space shuttle water vapor plume events.

The effects of IMF By on the middle thermosphere during a geomagnetically “quiet” period at solar minimum

There are significant differences between the Earth’s two hemispheres such as the Earth's magnetic field and the intensity of solar radiation due to Earth's tilt of the rotation axis with respect to the Sun.

Magnetic fields in the solar convection zone (major update)
