The quasi-biennial oscillation (QBO) of the zonal mean zonal wind is the primary mode of variability in the tropical lower stratosphere. The QBO is characterized by alternating...

The physical mechanism of low-cloud feedbacks is examined by using perturbed-parameter ensemble experiments in a unified scheme of boundary layer turbulence and shallow...

The strength of the Earth's magnetic field changes over time. We use simulations with the Coupled Magnetosphere-Ionosphere-Thermosphere model to investigate how the...

Approximately 1700 Pg of soil carbon (C) are stored in the northern circumpolar permafrost zone, more than twice as much C than in the atmosphere. The overall amount, rate, and...

In 1997, during the late stages of production of NCEP-NCAR Global Reanalysis (GR), exploration of a regional reanalysis project was suggested by the GR project's Advisory...

On behalf of the authors and readers of Reviews of Geophysics (RoG), the American Geophysical Union (AGU), and the broader scientific community, the editors wish to...

Observed changes in intense precipitation (e.g., the frequency of very heavy precipitation or the upper 0.3% of daily precipitation events) have been analyzed for over half of...

Characteristic properties of gravity waves from convection over the continental United States are derived from idealized high-resolution numerical simulations. In a unique...

We present airborne observations of the vertical gradient of atmospheric oxygen (delta(O-2/N-2)) and carbon dioxide (CO2) through the atmospheric boundary layer (BL) over the...

Measurements from actinic flux spectroradiometers on board the NASA DC-8 during the Atmospheric Tomography (ATom) mission provide an extensive set of statistics on how clouds...

Using the National Science Foundation (NSF)-NCAR Gulfstream V and the NSF-Wyoming King Air research aircraft during the Terrain-Induced Rotor Experiment (T-REX) in March-April...

Changing atmospheric composition due to human activities, primarily carbon dioxide (CO₂) emissions from fossil fuel burning, is already impacting ocean circulation,...

Between 2014 and 2018, the NOAA Office of Systems Architecture and Advanced Planning (OSAAP) conducted the NOAA Satellite Observing System Architecture (NSOSA) study to plan the...

Atmospheric storms are an important driver of changes in upper-ocean stratification and small-scale (1-100m) turbulence. Yet, the modifying effects of submesoscale (0.1-10 km)...

Emissions of biogenic volatile organic compounds (BVOC) from urban trees during and after blooming were measured during spring and early summer 2009 in Boulder, Colorado. Air...

We explore the use of machine learning (ML) techniques, namely, regression trees (RT), for the purpose of aviation turbulence forecasting at upper levels [20-45 kft (;6-14 km)...

We validate the Ozone Monitoring Instrument (OMI) Ozone Profile (PROFOZ) product from October 2004 through December 2014 retrieved by the Smithsonian Astrophysical Observatory...

Formaldehyde (HCHO) directly affects the atmospheric oxidative capacity through its effects on HOx. In remote marine environments, such as the tropical western Pacific (TWP), it...

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...
