We present in situ ion composition and velocity measurements during the August 2017 solar eclipse from the Enhanced Polar Outflow Probe (e-POP), which crossed the path of...

We investigated the diurnal variation of tropospheric nitrogen dioxide (NO2) over a cluster of high emission thermal power plants (HETPPs) in India using two products from...

For the numerical simulation of atmospheric flows that extend as high as the thermosphere, it is more appropriate to represent the upper boundary of the model domain as a...

Measurements of ozone vertical profiles are valuable for the evaluation of atmospheric chemistry models and contribute to the understanding of the processes controlling the...

Human land-use activities have resulted in large changes to the Earth's surface, with resulting implications for climate. In the future, land-use activities are likely to expand...

A total solar eclipse occurred in the Southern Hemisphere on 2 July 2019 from approximately 17 to 22 UT. Its effect in the thermosphere over South America was imaged from...

This study examines the influence of prescribed and prognostic aerosol model configurations on the formation of tropical cyclones (TCs) in the North Atlantic Ocean in Community...

The tropical Pacific Ocean cold tongue (CT) plays a major role in the global climate system. The strength of the CT sets the zonal temperature gradient in the Pacific that...

Deep convective transport of gaseous precursors to ozone (O-3) and aerosols to the upper troposphere is affected by liquid phase and mixed-phase scavenging, entrainment of free...

This Technical Note is a case study of one of the storms examined in the 1975 field season of the National Hail Research Experiment, during which the two primary observing...

We have analyzed data from a multi-site campaign to observe oscillations in the F5 star Procyon. The data consist of high-precision velocities that we obtained over more than...

The ensemble Kalman filter (EnKF) is a reliable data assimilation tool for high-dimensional meteorological problems. On the other hand, the EnKF can be interpreted as a particle...

The maximum future projected bioenergy expansion potential, in scenarios limiting warming to 2 degrees C or below, is equivalent to half of present-day croplands. We quantify...

We describe a new way to apply a spatial filter to gridded data from models or observations, focusing on low-pass filters. The new method is analogous to smoothing via...

One of the most robust responses of the climate system to future greenhouse gas emissions is the melting of Arctic sea ice. It is thus essential to elucidate its impacts on...

This report contains speakers' abstracts as presented at the workshop on Numerical Modeling and Physical Reality held at the Mesa Laboratory of NCAR on September 3-5, 1997 and...

This article does not have an abstract or article summary.

Processes in the climate system that can either amplify or dampen the climate response to an external perturbation are referred to as climate feedbacks. Climate sensitivity...

The long-term characteristics of four hydrometeor species (cloud water, cloud ice, rain, and snow) in precip-itating clouds over eastern China (divided into South China,...

A neural-network algorithm that uses CALIPSO lidar measurements to infer droplet effective radius, extinction coefficient, liquid-water content, and droplet number concentration...
