Monitoring changes in the ionosphere


Monitoring changes in the ionosphere Today’s Video of the Day comes from Science @ NASA and features a look at why scientists are closely monitoring the area where Earth’s atmosphere meets space, also known as the ionosphere.

The ionosphere can be easily affected by space weather from above and Earth’s weather from below, which can interrupt communication and GPS signals.

Now, NASA has launched two new satellite missions to track changes in the ionosphere: the Ionospheric Connection Explorer (ICON) mission and the Global-scale Observations of the Limb and Disk (GOLD) mission.  The monitoring of ionospheric perturbations can be used to provide improved ionospheric corrections for some application. The equivalent slab thickness is a measure of the width of the shape of the vertical electron density profile of the ionosphere.

The aim is to consider the following ionospheric phenomena: D-region absorption. Currently, this service provides vertical TEC maps, URSI ionospheric parameters and ionospheric perturbation products like the equivalent slab thickness and Rate Of Change of TEC Index. As seen above in video the Monitoring changes in the ionosphere has made significant affects and indirect measurement and calculation methods have been developed.
