We evaluate numerical simulations of the 3-D spatial and temporal electron densities produced by these particle populations through a comparison with incoherent scatter radar observations.

We argue that agreement among theoreticians on the numerical value of a particular physical parameter must still withstand the test of observation.

We combine GPS vertical total electron content and other complementary instruments to investigate the dynamics of the mid-latitude trough during non-storm time substorms for solar minimum condition and focus on…

The temporal behavior of the FeO and OH emissions was compared to model results from the one-dimensional and time-resolved model FeMOD, which describes the iron chemistry in the mesosphere/lower thermosphere.

We present a multi-instrument study on the variations of optical auroras and ionospheric electron densities during an interval of a series of fast earthward flows in the magnetotail on 3…

We present here the annual behavior of atmospheric water vapor on Mars, as observed by the OMEGA  spectrometer on board Mars Express during its first martian year.

We study here a series of bursts of fast tail flow that occurred on 5 March 2008 when four of the THEMIS probes were aligned in the tail from mid-tail…

A 5+ year record of satellite measurements of nitrogen dioxide columns from the Ozone Monitoring Instrument (OMI) is evaluated to establish the quality of the OMI retrievals and to test…

We compared diatom-diazotroph assemblage abundance to size-fractionated chlorophyll and satellite ocean color chlorophyll estimates to evaluate how DDAs affected ocean color estimates in the eastern and central North Pacific gyre…

We take advantage of the long history of plasma density measurements by a similar sensor on DMSP spacecraft to determine whether this change is typical of solar minima in general…

We formalize the properties of each piece of data and its processing history in a geographic ontology, and use declarative Semantic Web Rule Language (SWRL) rules to calculate the errors…

A method is developed for estimating F region ion composition from incoherent scatter radar (ISR) measurements during times of frictional ion heating.
