Climatology: Contrails reduce daily temperature range

  title={Climatology: Contrails reduce daily temperature range},
  author={David J. Travis and Andrew M. Carleton and Ryan G. Lauritsen},
The potential of condensation trails (contrails) from jet aircraft to affect regional-scale surface temperatures has been debated for years, but was difficult to verify until an opportunity arose as a result of the three-day grounding of all commercial aircraft in the United States in the aftermath of the terrorist attacks on 11 September 2001. Here we show that there was an anomalous increase in the average diurnal temperature range (that is, the difference between the daytime maximum and… Expand
Contrails, Natural Clouds, and Diurnal Temperature Range
Abstract The direct impact of aircraft condensation trails (contrails) on surface temperature in regions of high aircraft density has been a matter of recent debate in climate research. Based on dataExpand
Do contrails significantly reduce daily temperature range
[1] One of the most visible anthropogenic phenomena in the atmosphere is the occurrence of contrails. The direct effects of contrails on surface temperature are investigated on the basis of the dataExpand
Regional Variations in U.S. Diurnal Temperature Range for the 11–14 September 2001 Aircraft Groundings: Evidence of Jet Contrail Influence on Climate
The grounding of all commercial aircraft within U.S. airspace for the 3-day period following the 11 September 2001 terrorist attacks provides a unique opportunity to study the potential role of jetExpand
US Jet contrail frequency changes : influences of jet aircraft flight activity and atmospheric conditions
In the United States, the dramatic increase in jet fuel usage and kilometers flown has led to speculation of a similar increase in jet contrails. However, contrail occurrence depends heavily upon theExpand
Evaluating the Significance of the Contrail Effect on Diurnal Temperature Range Using the Eyjafjallajökull Eruption‐Related Flight Disruption
Meteorological data collected during the post‐9/11 flight grounding in the USA suggested that the removal of contrails increased diurnal temperature range (DTR), but subsequent research has contestedExpand
Composite Atmospheric Environments of Jet Contrail Outbreaks for the United States
Abstract The cirrus-level “condensation trails” (contrails) produced by jet aircraft are considered to influence surface climate and its recent changes. To reveal the synoptic atmosphericExpand
Impact of unusually clear weather on United States daily temperature range following 9/11/2001
Several investigators have suggested that the airline shutdown following the 9/11 terrorist attacks led to a reduction of jet contrails and an increase in the diurnal temperature range (DTR) acrossExpand
World War II contrails: a case study of aviation-induced cloudiness
Dense and persistent condensation trails or contrails were produced by daytime US Army Air Force (USAAF) bombing raids, flown from England to Europe during World War II (WW2). These raids occurred inExpand
Large Eddy Simulation of Early Stage Contrails: Effect of Atmospheric Properties
Prediction of growth and persistence of aircraft condensation trails involves uncertainties arising from numerous factors. It is sensitive to the atmospheric thermodynamic variables. Ambient relativeExpand
Condensation trails (contrails) are aircraft induced cirrus clouds, which may persist and grow to large cirrus cover in ice-supersaturated air, and may cause a warming of the atmosphere. This paperExpand


A Satellite-Based Climatic Description of Jet Aircraft Contrails and Associations with Atmospheric Conditions, 1977–79
Abstract The possible contribution of jet aircraft condensation trails (contrails) to recent observed increases in high cloudiness constitutes a potentially important human effect on climate that hasExpand
Contrail-Cirrus and Their Potential for Regional Climate Change
After reviewing the indirect evidence for the regional climatic impact of contrail-generated cirrus clouds (contrail-cirrus), the author presents a variety of new measurements indicating the natureExpand
Midwestern Cloud, Sunshine and Temperature Trends since 1901: Possible Evidence of Jet Contrail Effects
Abstract Records of monthly sky cover, sunshine and temperature for 1901–77 in a 10-state midwestern area were analyzed on a temporal and spatial basis to discern long-term trends and indications ofExpand
Estimates of cloud radiative forcing in contrail clusters using GOES imagery
Using data from the Geostationary Operational Environmental Satellite (GOES), the evolution of solar and longwave radiative forcing in contrail clusters is presented in several case studies. TheExpand
Radiative forcing by contrails
A parametric study of the instantaneous radiative impact of contrails is presented using three different radiative transfer models for a series of model atmospheres and cloud parameters. ContrailsExpand
A new perspective on recent global warming: asymmetric trends of daily maximum and minimum temperature
Abstract Monthly mean maximum and minimum temperatures for over 50% (10%) of the Northern (Southern) Hemisphere landmass, accounting for 37% of the global landmass, indicate that the rise of theExpand
