To provide new insights into the relationship between geomagnetic conditions and plasma irregularity scale-sizes, high-latitude irregularity spectra are computed using a novel...

We use the flux-transport dynamo prediction scheme introduced by Dikpati, de Toma, and Gilman (Geophys. Res. Lett. 33, L05102, 2006) to make separate simulations and predictions...

This work investigates middle atmosphere effects of the September 2005 solar flares and solar proton events (SPEs). X-17 and X-6.2 flares occurred on 7 and 9 September,...

The evolution of the microphysical structures of a subtropical squall line observed during the Observation, Prediction and Analysis of Severe Convection of China (OPACC) field...

Due to rapid data growth, statistical analysis of massive datasets often has to be carried out in a distributed fashion, either because several datasets stored in separate...

Satellite observations of carbon dioxide (CO₂) offer novel and distinctive opportunities for improving our quantitative understanding of the carbon cycle. Prospective...

We report on a global magnetohydrodynamical simulation of the solar convection zone, which succeeds in generating a large-scale axisymmetric magnetic component, antisymmetric...

We analyze the effects of the diurnal cycle of fire emissions (DCFE) and plume rise on U.S. air quality using the MUSICAv0 (Multi-Scale Infrastructure for Chemistry and Aerosols...

This User's Guide describes the overall design of the most recent version of the NCAR Community Climate Model, CCM2. In addition to in-depth information about running the CCM2...

This report presents the details of the governing equations, physical parameterizations, and numerical algorithms defining the version of the NCAR Community Atmosphere Model...

The terrestrial biosphere plays a major role in the global carbon cycle, and there is a recognized need for regularly updated estimates of land-atmosphere exchange at regional...

Citizen science promotes public participation in the discovery of new knowledge. Also known as volunteer monitoring or crowd sourcing, this form of public science has taken hold...

We examine the recent (1979-2010) and future (2011-2100) characteristics of the summer Arctic sea ice cover as simulated by 29 Earth system and general circulation models from...

This Atlas presents statistical analyses of the simulations submitted to the Aqua-Planet Experiment (APE) data archive. The simulations are from global Atmospheric General...

Under the sponsorship of the Natural Science Foundation of China (NSFC), a symposium on boundary layer meteorology was held at Nanjing University of Information Science and...

Trends in stratospheric trace gases like HCl, N2O, O3, and NOy show a hemispheric asymmetry over the last 2 decades, with trends having opposing signs in the Northern Hemisphere...

The NCAR Whole Atmosphere Community Climate Model, version 3 (WACCM3), is used to study the atmospheric response from the surface to the lower thermosphere to changes in solar...

This is the first volume in a set of four volumes which depict the upper air climatology of the world, covering selected climatic conditions in the Southern Hemisphere. Volume I...

The papers contained in the 1976 Technical Note NCAR/TN-119+PROC represent the research and programming carried out / 12 students in the Computing Facility summer programs...

Water is a critical resource that causes significant challenges to inhabitants of the western United States. These challenges are likely to intensify as the result of expanding...
