The first study to simultaneously investigate precipitation and cloud structures in tropical weather systems concludes observation systems significantly overestimate the height of raining clouds.

Improving Retrievals for Vertically Inhomogeneous Warm Clouds
Cloud droplet size changes with height, but passive sensors are virtually blind to see it; however, combining passive with active sensors helps profile it in vertically inhomogeneous warm clouds.
What Drives Surface Winds in a Deep Valley?
Surface winds in a Himalayan valley are found to vary daily and seasonally due to factors including pressure gradient, advection, turbulent vertical mixing, and the presence of glaciers.
How Brown Carbon and Coatings on Black Carbon Affect Absorption
While ambient black carbon absorption is shown largely independent of coatings, distinct types of atmospheric brown carbon coexist, deriving from primary emissions and secondary processing.
Observations Show Gravity Waves Above Antarctica Dance in Winter
Year-round observations show gravity waves above Antarctica exhibit seasonal patterns that peak in winter, which could help researchers trace the source of this mysterious phenomenon.
Managing Uncertainties in Climate Engineering
Control theory and climate engineering meet in a new special issue of JGR: Atmospheres.
Improving Retrievals for Partially Cloudy Pixels
Cloud retrievals for partly cloudy pixels might be able to be improved by using high-resolution samples in a visible to near-infrared band, which many satellite sensors offer.
What Makes a Terrestrial Gamma-Ray Flash in Thunderclouds?
Two lightning flashes were observed in the same location: One produced a bright gamma-ray flash with about 1000 counts per millisecond, but the other did not.
Greenhouse Gas Inventories Underestimate Methane Emissions
A new study in the Baltimore-Washington metropolitan area reveals prior estimates may significantly underrepresent methane emissions, particularly from landfills and natural gas systems.
Retrieving Tropospheric Ozone from Ground-based Spectroscopy
A new technique can retrieve the profile of ozone from surface to tropopause by MAX-DOS ground-based measurements.
