New aircraft survey data show that although atmospheric chemistry above remote ocean regions is a considerable source of methanol production, the ocean’s net methanol emission is minor.
Turbulence causes local variations in relative humidity, which can push particles past a critical saturation threshold for droplet nucleation.
The fifth major update of land surface air temperature data from the Climatic Research Unit and the Met Office has extended the time series, included more stations, and used better processing methods.
HadCRUT5, the new version of the Met Office Hadley Centre/Climatic Research Unit global surface temperature dataset from 1850 to 2018, has extended and improved the previous temperature record.
Wildfires create airborne plumes of organic and inorganic matter as they burn. These particles can nucleate cloud-forming ice crystals and affect cloud dynamics, precipitation, and climate.
New high-altitude aircraft observations identify unexpected high levels of halogen-containing species entering the stratosphere above the summertime Asian monsoon.
In-situ data gathered from an aircraft flying over 23 western US wildfires in 2018 reveal the importance of reduced nitrogen, shedding insights on ozone and aerosol formation from wildfires.
The destructive winds and rain of Hurricane Maria in 2017 caused a dramatic transformation to Puerto Rico’s landscape and altered the characteristics of land-air interaction.
An assessment and comparison of the performances of climate models participating in three phases of the Coupled Model Intercomparison Project (CMIP3, CMIP5 and CMIP6).
New high-resolution imaging and modeling reveal the first evidence of enhanced turbulence due to gravity wave modulation of Kelvin-Helmholtz instabilities.
