Technique: We present a method to determine the pressure at which significant cloud opacity is present between 2 and 6 bars on Jupiter. We use (a) the strength of a Fraunhofer absorption line in a zone to determine the ratio of reflected sunlight to thermal emission, and (b) pressure-broadened line profiles of deuterated methane (CH3D) at 4.66 μm to determine the location of clouds. We use radiative transfer models to constrain the altitude region of both the solar and thermal components of…

The Gas Composition and Deep Cloud Structure of Jupiter's Great Red Spot
We have obtained high-resolution spectra of Jupiter’s Great Red Spot (GRS) between 4.6–5.4 μm using telescopes on Mauna Kea to derive gas abundances and to constrain its cloud structure between 0.5–5

This thesis uses infrared observations from spacecraft and ground-based telescopes to investigate the composition and cloud structure of the jovian atmosphere. It focuses on a single spectral region,
Ammonia in Jupiter's Troposphere From High‐Resolution 5 μm Spectroscopy
Jupiter's tropospheric ammonia (NH3) abundance is studied using spatially resolved 5 μm observations from the cryogenic high‐resolution infrared spectrograph (CRIRES) at the European Southern
Rotational Light Curves of Jupiter from Ultraviolet to Mid-infrared and Implications for Brown Dwarfs and Exoplanets
Rotational modulations are observed on brown dwarfs and directly imaged exoplanets, but the underlying mechanism is not well understood. Here we analyze Jupiter’s rotational light curves at 12
Near-Infrared atmospheric modelling of Jupiter's South Equatorial Belt (SEB) observed with AAT/IRIS2
Near-Infrared spectra of Jupiter's South Equatorial Belt (SEB) with AAT/IRIS2 in the H and K bands at a resolving power of R ∼ 2400 have been obtained. By creating lineby-line radiative transfer
Jupiter’s Mesoscale Waves Observed at 5 μm by Ground-based Observations and Juno JIRAM
TLDR
The NEB underwent a new expansion and contraction episode in 2016-17 with associated cyclone-anticyclone formation, which could explain why the mesoscale wave pattern was more vivid in 2017 than ever before.
On the clouds and ammonia in Jupiter’s upper troposphere from Juno JIRAM reflectivity observations
We analyse spectra measured by the Jovian Infrared Auroral Mapper (JIRAM, a payload element of the NASA Juno mission) in the 3150–4910 cm−1 (2.0–3.2 μm)  range during the perijiove passage of 2016
Characterization of Mesoscale Waves in the Jupiter NEB by Jupiter InfraRed Auroral Mapper on board Juno
In 2017, the Jupiter InfraRed Auroral Mapper (JIRAM), on board the NASA-ASI Juno mission, observed a wide longitude region (50° W–80° E in System III) that was perturbed by a wave pattern centered at
