Land, ocean, and atmospheric models are often implemented on different spherical grids. As a conseqence coupling these model components requires state variables and fluxes to be...

Historical global land use and land cover change (LULCC) emissions of 160PgC represent a third of all human CO2 emissions from 1850 to 2010. Future land management decisions...

In August-September 2010, NASA, NOAA, and the National Science Foundation (NSF) conducted separate but closely coordinated hurricane field campaigns, bringing to bear a combined...

Chemical modelling studies have been conducted over north-western Europe in summer conditions, showing that night-time dinitrogen pentoxide (N₂O₅) heterogeneous reactive uptake...

In this study, a fuzzy logic algorithm is developed to provide objective guidance for the prediction of afternoon thunderstorms in northern Taiwan using preconvective predictors...

This study describes a set of idealized simulations in which westerly vertical wind shear increases from 3 to 15 m s(-1) at different stages in the life cycle of an intensifying...

The region around the main Hawaiian Islands (MHI) is characterized by a permanent thermocline, and numerous processes have been proposed to facilitate phytoplankton blooms in...

Observational analysis has indicated a strong connection between the stratospheric quasi-biennial oscillation (QBO) and tropospheric Madden-Julian oscillation (MJO), with MJO...

The National Center for Atmospheric Research (NCAR) led a partnership to advance the state-of-the-science of solar power forecasting by designing, developing, building,...

Guided by ground-based radar and lidar profiling at the Barbados Cloud Observatory (BCO), this study evaluates trade-wind cloudiness in ECMWF's Integrated Forecast System (IFS)...

Simulating deep solar convection and its coupled mean-field motions is a formidable challenge where few observational results constrain models that suffer from the nonphysical...

This article does not have an abstract or article summary.

Interannual variations in the flux of carbon dioxide (CO2) between the land surface and the atmosphere are the dominant component of interannual variations in the atmospheric...

Two schemes for modeling condensation in warm nonprecipitating clouds are compared. The first one is the efficient bulk condensation scheme where cloudy volumes are always at...

Thermospheric composition (O/N2 ratio) is well known to have a great impact on the variation of daytime ionospheric electron density. This study aims to investigate the local...

Multimodel ensembles of back trajectories calculated from four different analysis data sets and two different trajectory formulations ("diabatic" and "kinematic") are analyzed...

Foreshock transients such as hot flow anomalies (HFAs) are frequently observed in the dayside foreshock. They can disturb the local bow shock, magnetopause, and consequently the...

The purpose of this document is to explain how to maintain programs and other small files for use on NCAR's batch computers. Annotated examples are used to show how most common...

During the Ice in Clouds Experiment–Layer Clouds (ICE-L), aged biomass-burning particles were identified within two orographic wave cloud regions over Wyoming using single-...

This summer the Boulder science community is commemorating the anniversaries of several key historical events in solar physics and space weather. Seventy-five years ago in 1940...
