Code and data for "Juno Microwave Radiometer Observations Reveal a Warmer Polar Atmosphere on Jupiter"

This repository hosts the code and data used to retrieve the Jovian north polar mean atmospheric thermal/compositional structure. The work is based on the observations of the six-channel Microwave Radiometer oboard the NASA's Juno spacecraft, during perijove passes from PJ51 to PJ61.

Data description

Table stores the coefficients of brightness temperature model characterizing the angluar depandence of atmospheric emission of the Jovian north pole ($\phi>75^\circ$N), reduced by Z.Z. from the raw antenna temperature measurements of Juno MWR during May 2023 to May 2024.

Formula refers to the quadratic polynomial model porposed by F. Oyafuso et al. (2020, ESS):

$T_b(\mu)= [c_0 - c_1 \frac{1-\mu}{0.2}+c_2 \frac{(\mu-0.8)(1-\mu)}{0.08}]\cdot\xi (\mu)$

with which brightness temperatures at any emission angle ($\mu \lt 0.6$) can be determined.

Code description

The ZIP file freezes the v1.0 version code by the manuscript submission, which is originally reposited on the GitHub repo: https://github.com/jihenghu/Jupiter_northpole, under MIT Linces. 

The code uses CANOE (Comprehensive Atmosphere N' Ocean Engine) as dependency. the version used here is achived at https://github.com/jihenghu/canoe/tree/jh/junoemcee.
