Agricultural expansion and management have greatly increased global food production and altered Earth's climate by changing physical and biogeochemical properties of terrestrial...

I hope you will join me in welcoming Dr. Daniel Welling of University of Michigan and Dr. T. Paul O'Brien of the Aerospace Corporation to the Space Weather (SWE) editorial team....

The influence of the high-latitude energy inputs and heating distributions on the global thermosphere are investigated by coupling a new empirical model of the Poynting flux...

Nitryl chloride (ClNO2) plays an important role in the budget and distribution of tropospheric oxidants, halogens, and reactive nitrogen species. ClNO2 is formed from the...

Rayleigh lidar measurements of stratospheric and lower mesospheric temperatures obtained at the Urbana Atmospheric Observatory (40.1degreesN, 88.1degreesW) on 17/18 November...

Atmospheric new particle formation (NPF) produces large numbers of nanoparticles which can ultimately impact climate. A firm understanding of the identity and contribution of...

The diurnal cycle of precipitation and precipitation variances at different time scales are analyzed in this study based on multiple high-resolution 3-h precipitation datasets....

This paper reports observation of moderate to intense scintillations, at S band of Indian Regional Navigation Satellite System (IRNSS). During current solar cycle 25, these...

This report analyzes the detailed structure and evolution of radar echoes observed in a multicellular hailstorm. Part I describes general environmental conditions, overall radar...

By injecting SO(2)into the stratosphere at four latitudes (30 degrees, 15 degrees N/S), it might be possible not only to reduce global mean surface temperature but also to...

This study explores the role of the stratosphere as a source of seasonal predictability of surface climate over Northern Hemisphere extratropics both in the observations and...

Given that more than half of the world's population currently resides in cities, further understanding of the potential impact of future climate change on urban areas is needed....

Active regions on the solar surface are generally thought to originate from a strong toroidal magnetic field generated by a deep seated solar dynamo mechanism operating at the...

A modified microphysics scheme is implemented in the Community Atmosphere Model, version 5 (CAM5). The new scheme features prognostic precipitation. The coupling between the...

The Scientific Computing Division is charged with providing computing support for research conducted by NCAR staff and for extending the computing resources of university...

Anthropogenic changes in the variability of precipitation stand to impact both natural and human systems in profound ways. Precipitation variability encompasses not only...

The assimilation of wind observations in the form of speed and direction (asm_sd) by the Weather Research and Forecasting Model Data Assimilation System (WRFDA) was performed...

Emissions of aerosols and their precursors are declining due to policies enacted to protect human health, yet we currently lack a full understanding of the magnitude,...

The Weather Research Forecast (WRF) model imposed by the large-scale advective forcing derived from observed data representing an average of gridded data fields over the South...

This paper uses the "Super Outbreak" of 2011 as a case study to examine the potential gaps between the dissemination of severe weather warnings and the public's behavioral...
