Color and aerosol changes in Jupiter after a North Temperate Belt disturbance

Vertical Distribution of Aerosols and Hazes Over Jupiter's Great Red Spot and Its Surroundings in 2016 From HST/WFC3 Imaging

“…The “Tropospheric m i 1” curve is almost equal to the one presented in Pérez‐Hoyos et al. (2020), but with a slight reduction of its value at 600 nm following a preliminary analysis. The tropospheric curve with the lower values is again a tenth of the higher one.…”

“…The a priori models were evaluated using two different criteria: (a) The overall fit of models and observations at each point and (b) the fit of the measured and modeled limb-darkening with I F /   0 and E k calculated via Equation 3 (Irwin et al, 2021;Pérez-Hoyos et al, 2020). The first criterion is evaluated in terms of the following error function:…”

“…We use the NEMESIS radiative transfer suite (Irwin et al., 2008) in order to retrieve atmospheric parameters from the observed spectra as in our previous works (Pérez‐Hoyos et al., 2018, 2020; Sanz‐Requena et al., 2019; Irwin et al., 2021). NEMESIS is initiated from an a priori model atmosphere divided in homogeneous layers to obtain synthetic spectra from the multiple scattering calculations on each layer by means of the doubling‐adding technique (Hansen & Travis, 1974).…”

Jupiter’s Great Red Spot: Strong Interactions With Incoming Anticyclones in 2019

“…(2005). Previous work has shown that this kind of model accounts well for the observed reflectivity at this spectral resolution in both Jupiter (Pérez‐Hoyos et al., 2020) and Saturn (Sánchez‐Lavega, Garcia‐Melendo, et al., 2020; Sánchez‐Lavega, Garcia‐Munoz, et al., 2020).…”

“…This spectral region is mainly sensitive to the particle number density and optical depth of the aerosol layers of the hazes. The description of the atmospheric parameters defining the aerosol vertical distribution in our radiative transfer model (see section 2.4) can be summarized as follows (Pérez‐Hoyos et al., 2020): An uppermost stratospheric haze composed of small particles; an intermediate tropospheric haze of micron‐sized particles that dominate the reflectivity measured in this work; and a bottom cloud with a limited effect on the modeling (Figures 10b and Table ). While the uppermost and bottom aerosol layers were modeled with a single free parameter that accounts for the total optical thickness of the layer, the intermediate and most influential layer requires three free parameters for the vertical distribution (bottom pressure P bot , peak particle density N and fractional scale height), two parameters to describe the particle size distribution (effective radius r eff and dispersion σ ) and the imaginary refractive index ( mi ) as a function of wavelength.…”
