Improving model-satellite comparisons of sea ice melt onset with a satellite simulator [PDF]

open access: yesThe Cryosphere, 2022
Seasonal transitions in Arctic sea ice, such as the melt onset, have been found to be useful metrics for evaluating sea ice in climate models against observations. However, comparisons of melt onset dates between climate models and satellite observations

Satellite Optical Brightness

open access: yesThe Astronomical Journal, 2023
The apparent brightness of satellites is calculated as a function of satellite position as seen by a ground-based observer in darkness. Both direct illumination of the satellite by the Sun as well as indirect illumination due to reflection from the Earth
