Evaluation of GLO: a Solar Occultation Instrument for Measuring Atmospheric Trace Species on CubeSat Missions
… (GFCR (Gas Filter Correlation Radiometry) Limb Occultation) prototype, a new small-form-factor design that enables sub-kilometer resolution of the vertical profile of atmospheric trace species to determine radiative influences. This technology improves SWAP (Size, Weight, And Power) over …

Understanding Middle Atmospheric Composition Variability from the Solar Occultation for Ice Experiment Instrument and Other Datasets
… and improve phenomenon-centric observations. The Solar Occultation for Ice Experiment (SOFIE) is one of the two instruments on the Aeronomy of Ice in the Mesosphere (AIM) spacecraft. The studies presented in this dissertation primarily focus on the use of SOFIE observations combined with results …

Observation of sulphate aerosols and SO2 from volcanic eruptions using data from the Atmospheric Chemistry Experiment (ACE)
… aerosol retrievals determined using the infrared solar occultation spectra recorded with ACE-FTS are presented here. The size distribution parameters, aerosol volume slant column and composition of the sulphate aerosol were obtained using a least-squares algorithm, employing a continuum spectrum …

Development and Application of a Versatile Balloon-Borne DOAS Spectrometer for Skylight Radiance and Atmospheric Trace Gas Profile Measurements
… available from in-situ, or UV/vis/near IR solar occultation observations performed on the same payload. Reasonable agreement is found between (a) measured and RT calculated limb radiances and (b) inferred limb O3, NO2, and BrO and correlative profile measurements when properly accounting …

Limb scatter measurements of high altitude cloud distributions
… to those by Wang et al. (1996) who used SAGE II solar occultation measurements of cirrus clouds. The cloud detection technique is applied to three case studies. Cloud top detections are used to support results presented in Dessler (2009) who theorized the local relative humidity controls either …

Vertically Propagating Tides in the Martian Atmosphere
… are identified in the upper atmosphere using solar occultation observations for the first time. The eastward propagating non-migrating tides are shown to dominate the tidal spectrum. A key finding is that the relative importance of the tides with different periods is more significant at high …

Trend Analyses of the Abundances of Atmospheric Molecules
… distributions have been determined from infrared solar occultation measurements of the Atmospheric Chemistry Experiment (ACE) satellite mission. ACE measurements are made with a high resolution Fourier transform spectrometer (ACE-FTS). Annual and seasonal latitudinal fractionation (δ value) …
