Submesoscale dynamics play a key role in setting the stratification of the ocean surface mixed layer and mediating air-sea exchange, making them especially relevant to...

One of the grand challenges in heliophysics is the characterization of coronal mass ejection (CME) magnetic structure and evolution from eruption at the Sun through heliospheric...

High-altitude atmospheric electricity measurements have been used to calculate the conduction (Wilson) currents that are supplied to the global electric circuit (GEC) by...

La deuxième conférence internationale Iasi (Infrared Atmospheric Sounding Interferometer), qui s'est tenue à Sévrier (Haute-Savoie) du 24 au 29 janvier 2010, a rassemblé 150...

We report here the concept of using near-real time observations from a coronagraph to provide early warning of a fast coronal mass ejection (CME) and the possible onset of a...

The Geophysical Fluid Dynamics Laboratory (GFDL)'s System for High‐resolution prediction on Earth‐to‐Local Domains (SHiELD) model typically uses the National...

In this study, Global Ionosphere Specification (GIS) based on Gauss-Markov Kalman filter assimilation of slant total electron content observed from ground-based global...

The fluctuation dissipation theorem (FDT), a classical result coming from statistical mechanics, suggests that, under certain conditions, the system response to external forcing...

The linear stability of a zonal flow confined in a domain within horizontal top and bottom boundaries is examined under full consideration of the Coriolis force. The basic zonal...

High Resolution Dynamics Limb Sounder (HIRDLS) and Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) measurements of cirrus frequency of occurrence in...

This report summarizes the parameterizations of surface processes currently being used in the NCAR grid point GCM. It treats in particular: (i) the calculation of ground, snow...

This paper develops an algorithm for radial basis function (RBF) local node refinement and implements it for vortex roll-up and transport on a sphere. A heuristic based on an...

It is the purpose of this paper to provide a comprehensive documentation of the new NCAR (National Center for Atmospheric Research) version of the spectral element (SE)...

Recent NOAA Hazardous Weather Testbed Spring Forecasting Experiments have emphasized the sensitivity of forecast sensible weather fields to how boundary layer processes are...

The main objective of this study is to observationally constrain processes in tropical and midlatitude mesoscale convective systems (MCSs), and to use these constraints for...

In the Southern Hemisphere and tropics, the main contribution to carbon monoxide (CO) variability is from fire emissions, which are connected to climate through the...

Geographical and seasonal variations of gravity wave events in the upper mesosphere were investigated using the nightglow imaging data obtained by the Visible and near-Infrared...

We present a synthesis of locally absent (or "missing") growth rings across the Northern Hemisphere based on 2359 publicly available tree ring-width records. During the last...

Understanding the earth as a system requires integrating many forms of data from multiple fields. Builders and funders of the cyberinfrastructure designed to enable open data...

Ultra low frequency (ULF; 1 mHz ‐ several Hz) waves are key to energy transport within the geospace system, yet their contribution to Joule heating in the upper...
