ionosphere

Converse of object

• study: It is used to study the northern polar ionosphere.
• perturb: The model provides a useful, yet simple tool for modeling of the perturbed ionosphere.
• monitor: A new method of monitoring the ionosphere based on radio tomography can be used to create two-dimensional images of electron density.

Adjective modifier

• polar: It is used to study the northern polar ionosphere.
• low: The feedback process which destabilizes these irregularities is associated with the heating effect of parallel electron currents in the collisional lower ionosphere.
• auroral: In this instance plasma convection appeares to play the dominant role in forming the large-scale spatial structure of the nightside auroral ionosphere.
• European: Disturbances of the western european ionosphere during the total solar eclipse of 11 august 1999 measured by a wide ionosonde and radar network.
• equatorial: The Observatory is the premier scientific facility in the world for studying the equatorial ionosphere.
• Jovian: Correlations between the three parameters were looked at to study the process involved in energy transport in the Jovian ionosphere.

Modifies a noun

• reentry: CURLY HAIRED TECH: T minus 30 seconds to ionosphere reentry.

Preposition: during

• eclipse: Disturbances of the western european ionosphere during the total solar eclipse of 11 august 1999 measured by a wide ionosonde and radar network.
• interval: In two previous studies we have found evidence of plasma convection driven in the nightside ionosphere during intervals of northward IMF.

Noun used with modifier

• high-latitude: The convection electric field during this interval is measured in the high-latitude ionosphere using the northern hemisphere SuperDARN HF radar network.
• topside: Range coverage is from 90 to 375 km, so this experiment is not useful for studying the topside ionosphere.
• dayside: Excellent coverage of the entire dayside high-latitude ionosphere was achieved by all of the northern hemisphere SuperDARN radars.
• reference: Simulated GPS data, constructed assuming that the ionosphere is the international reference ionosphere, are inverted via the Multi Instrument Data Analysis System.
• latitude: The aim of the collaboration between Sheffield and Aberystwyth is to combine modeling studies with experimental observations of the high- latitude ionosphere.

Possessives

• earth: Hear the whistles, pops, squeeks, chirps and pings caused by the electrical activity in the Earth's ionosphere.
• planet: The instrument will now be used to look for water below the Martian surface and to study the planet's ionosphere.

Preposition: with

• observation: Investigations of long-term trends in the ionosphere with world-wide ionosonde observations.
