Radiative Forcing and Ozone Depletion of a Decade of Satellite Megaconstellation Missions Open
Satellite megaconstellations (SMCs) are driving rapid increases in rocket launch and re-entry rates, emitting pollutants throughout the atmosphere. The environmental cost of SMCs lacks characterization to determine the need for regulation.…

Climate Forcing due to Future Ozone Changes: An intercomparison of metrics and methods Open
We use Earth system models and a chemistry transport model to determine the radiative forcing due to changes in ozone Three different measures of radiative forcing (instantaneous: IRF, stratospheric-temperature adjusted: SARF, effective: E…

Developing inventories of by-products from satellite megaconstellation launches and disposal to determine the influence on stratospheric ozone and climate Open
There are close to 6000 megaconstellation satellites in low-Earth orbit comprising 65% of all satellites orbiting Earth. The growth in satellite megaconstellations has driven surges in rocket launches and re-entry destruction of spent sate…
