Co-located FUV Limb Imaging and Nadir-Viewing Photometry of the Nighttime Ionosphere
Abstract
The GPS Radio Occultation and Ultraviolet Photometer Co-located (GROUP-C) and the Limb-Imaging Ionospheric and Thermospheric Extreme-Ultraviolet Spectrograph (LITES) are a complementary pair of ionospheric remote sensing experiments collecting data from the International Space Station (ISS) as part of the Space Test Program Houston #5 payload (STP-H5). LITES views the atmospheric limb in the orbital plane in the wake of the ISS, and measures vertical profiles of extreme- and far-ultraviolet airglow, including the 91.1 and 135.6 nm emissions that both derive from radiative recombination of oxygen ions (O+) and electrons. GROUP-C includes a nadir-viewing, high-sensitivity photometer measuring the 135.6 nm emission, along with a GPS receiver that provides radio occultation and scintillation measurements. We present the measurements, analysis, and modeling of the nighttime UV emissions measured by GROUP-C and LITES and the implications for potential 2D tomographic inversions from this unique measurement set.
