Meteorological Satellites Observe Temperatures On Venus

by Keith CowingJuly 2, 2025July 2, 2025

Imaging data from Japan’s Himawari-8 and -9 meteorological satellites have been successfully used to monitor temporal changes in Venus’ cloud-top temperature, revealing unseen patterns in the temperature structure of various […]

Progression of the simulations, combining the cloud-free simulations (left most panel), with the fully cloudy simulations (panel two), to yield the simulations using the cloud fraction map (panel three). The last panel shows the DSCOVR/EPIC observation that is being reproduced. Observations and synthetic images show very similar dynamic range, absolute flux calibration and coloring. No special or arbitrary scaling or calibrations were applied to the model, nor the data. -- astro-ph.EP

The Pale Blue Dot: Using the Planetary Spectrum Generator to Simulate Signals from Hyper Realistic Exo-Earths

by Keith CowingNovember 20, 2024November 20, 2024

The atmospheres and surfaces of planets show tremendous amount of spatial variation, which has a direct effect on the spectrum of the object, even if this may not be spatially […]
