Spectropolarimetry as a Means to Address Cloud Composition and Habitability for a Cloudy Exoplanetary Atmosphere in the Habitable Zone
Robert A. West, Philip Dumont, Renyu Hu +3
In our solar system, the densely cloud-covered atmosphere of Venus stands out as an example of how polarimetry can be used to gain information on cloud composition and particle mea…
Assessing Planetary Complexity and Potential Agnostic Biosignatures using Epsilon Machines
Stuart Bartlett, Jiazheng Li, Lixiang Gu +6
We present a new approach to exoplanet characterisation using techniques from complexity science, with potential applications to biosignature detection. This agnostic method makes…
Machine learning-based aerosol characterization using OCO-2 O2 A-band observations
Sihe Chen, Vijay Natraj, Zhao-Cheng Zeng +1
Aerosol scattering influences the retrieval of the column-averaged dry-air mole fraction of CO2 (XCO2) from the Orbiting Carbon Observatory-2 (OCO-2). This is especially true for s…
Earth as a Proxy Exoplanet: Deconstructing and Reconstructing Spectrophotometric Light Curves
Lixiang Gu, Siteng Fan, Jiazheng Li +7
Point source spectrophotometric ("single-point") light curves of Earth-like planets contain a surprising amount of information about the spatial features of those worlds. Spatially…
Constraining the vertical distribution of coastal dust aerosol using OCO-2 O2 A-band measurements
Zhao-Cheng Zeng, Sihe Chen, Vijay Natraj +6
Quantifying the vertical distribution of atmospheric aerosols is crucial for estimating their impact on the Earth energy budget and climate, improving forecast of air pollution in…
Earth as an Exoplanet: A Two-dimensional Alien Map
Siteng Fan, Cheng Li, Jia-Zheng Li +5
Resolving spatially-varying exoplanet features from single-point light curves is essential for determining whether Earth-like worlds harbor geological features and/or climate syste…
Remote sensing of angular scattering effect of aerosols in a North American megacity
Zhao-Cheng Zeng, Feng Xu, Vijay Natraj +5
The angle-dependent scattering effect of aerosols in the atmosphere can be used to infer their compositions, which in turn is important to understand their impacts of human health…
Learning Radiative Transfer Models for Climate Change Applications in Imaging Spectroscopy
Shubhankar Deshpande, Brian D. Bue, David R. Thompson +2
According to a recent investigation, an estimated 33-50% of the world's coral reefs have undergone degradation, believed to be as a result of climate change. A strong driver of cli…
Using Deep Space Climate Observatory Measurements to Study the Earth as An Exoplanet
Jonathan H. Jiang, Albert J. Zhai, Jay Herman +7
Even though it was not designed as an exoplanetary research mission, the Deep Space Climate Observatory (DSCOVR) has been opportunistically used for a novel experiment, in which Ea…
A Multiple Scattering Polarized Radiative Transfer Model: Application to HD 189733b
Pushkar Kopparla, Vijay Natraj, Xi Zhang +3
We present a multiple scattering vector radiative transfer model which produces disk integrated, full phase polarized light curves for reflected light from an exoplanetary atmosphe…
Information Content of Exoplanetary Transit Spectra: An Initial Look
M. R. Line, X. Zhang, G. Vaisht +3
It has been shown that spectroscopy of transiting extrasolar planets can potentially provide a wealth of information about their atmospheres. Herein, we set up the inverse problem…
