Contrail coverage over the United States before and during the COVID-19 pandemic

Vincent R. Meijer et al.

Summary: Contrails, which contribute to climate change caused by aviation, have uncertain coverage estimates. This study provides observation-based estimates of diurnal, seasonal, and regional variability in contrail coverage in the contiguous United States using a deep learning algorithm and satellite images. The results show a significant reduction in contrail coverage in 2020 compared to 2019, and the diurnal pattern of contrail coverage aligns with flight traffic.

The contribution of global aviation to anthropogenic climate forcing for 2000 to 2018

D. S. Lee et al.

Summary: Global aviation operations contribute to anthropogenic climate change by emitting carbon dioxide, nitrogen oxides, water vapor, soot and sulfate aerosols, and increasing cloudiness due to contrail formation. The growth of aviation activity and climate change impact has shown a marked increase in recent years, with contrail cirrus being the largest contributor to the warming effect.

Climate Impacts of COVID-19 Induced Emission Changes

A. Gettelman et al.

Summary: The COVID-19 pandemic led to reductions in aerosol and precursor emissions, affecting aerosol-cloud interactions and temperatures. The average overall Effective Radiative Forcing (ERF) peaks at +0.29 Wm(-2) in spring 2020, with a small impact on global surface temperature. The aerosol changes have the largest contribution to radiative forcing and temperature changes due to COVID-19 affected emissions.

An Observational Constraint on Aviation-Induced Cirrus From the COVID-19-Induced Flight Disruption

Ruth A. R. Digby et al.

Summary: Global aviation decreased sharply during the Covid-19 pandemic, providing a unique opportunity to study aviation-induced cirrus clouds. However, satellite observations did not show a significant global response to the reduction in aviation, indicating that previous estimates of aviation-induced cirrus may have been overestimated. Additionally, there was no notable impact on diurnal surface air temperature range, suggesting that the warming effect of cirrus clouds from aviation may be smaller than previously believed.

Aviation Contrail Cirrus and Radiative Forcing Over Europe During 6 Months of COVID-19

U. Schumann et al.

Summary: The COVID-19 pandemic significantly reduced air traffic and contrail cover over Europe, with slight improvements in the agreement between model predictions and observations mainly attributed to contrail cirrus contributions.

Climate impact of aircraft-induced cirrus assessed from satellite observations before and during COVID-19

Johannes Quaas et al.

Summary: Aircraft contrails are believed to increase high-level cloudiness, but the magnitude of this effect and its contribution to radiative forcing from the aviation sector are uncertain. The COVID-19 outbreak led to a significant reduction in air traffic, allowing for the study of the anthropogenic contribution to cirrus clouds.

Air traffic and contrail changes over Europe during COVID-19: a model study

Ulrich Schumann et al.

Summary: The study analyzes the changes in air traffic and contrail cirrus over the period of March to August 2020 in Europe, comparing them to the same period in 2019. The reduction in air traffic during the COVID-19 pandemic resulted in a decrease in contrail length and coverage, leading to significant reductions in shortwave and longwave radiative forcing. The study also introduces new methods to account for water vapor exchange between contrails and background air and to assess radiative forcing changes due to contrail-contrail overlap.
