The tiny ionospheric photometer (TIP) and GPS occultation experiment (GOX) onboard FORMOSAT-3/COSMIC (F3/C) are employed to measure the OI 135.6 nm intensities in the nadir direction and the total electron content (TEC) between the F3/C and GPS satel

The Constellation Observing System for Meteorology, Ionosphere, and Climate (FORMOSAT-3/COSMIC) is a constellation of six microsatellites that was launched into low-Earth orbit on 14 April 2006. Each FORMOSAT-3/COSMIC satellite contains a GPS Occulta

We investigate the spatial variability of electron densities in the nightside ionosphere and its effects on very-low frequency (VLF) wave propagation using a suite of instruments from the FORMOSAT-3/Constellation Observing System for Meteorology Iono

The Tiny Ionospheric Photometer (TIP) on the Constellation Observing System for Meteorology, Ionosphere, and Climate (FORMOSAT-3/COSMIC) characterizes the nighttime ionosphere using 135.6-nm radiative recombination emission. TIP measures horizontal s

It has long been known that the ionospheric absorption of HF radio waves is dependent on the electron density in the ionosphere. This paper examines two aspects of the absorption calculation that have not been as thoroughly investigated. First, the c

The Special Sensor Ultraviolet Limb Imager (SSULI) instruments are ultraviolet limb scanning sensors flying on the United States Air Force Defense Meteorological Satellite Program (DMSP) Block 5D-3 satellites. The SSULIs cover the 800-1700 A waveleng

One of the challenges for the utilization of HF radiowaves in practical applications is to understand how the signals propagate in time- and range-dependent multipath environments. For typical quiescent ionospheric conditions it is often reasonably s

This study is focused on investigating how well the day-to-day variability of HF propagation in the bottomside ionosphere can be simulated using a state-of-the-art ionosphere model coupled to a whole atmosphere model driven by the lower atmosphere. T
