Moist anelastic and compressible numerical solutions to the planetary baroclinic instability and climate benchmarks are compared. The solutions are obtained by applying a...

Detection of changes in climate responses is essential to facilitate appropriate adaptation actions to be taken by decision makers, particularly where changes in the arrival...

This Technical Note supplements the Carbone et al. (2001) study, for which meridionally averaged composites of national radar reflectivity were used to compile seasonal...

A simplified version of the near-boundary eddy flux parameterization developed recently by Ferrari et al. has been implemented in the NCAR Community Climate System Model (CCSM3)...

Globally, secondary organic aerosol (SOA) is mostly formed from emissions of biogenic volatile organic compounds (VOCs) by vegetation, but it can be modified by human activities...

Ensembles of 21st century climate projections made using a state of the art global climate model are analyzed to explore possible changes in spring snow cover and summer air...

The following report summarizes recent results of balloon-borne observations separately for the various disciplines: infrared astronomy, ultraviolet astronomy, X-ray astronomy,...

Quantifying the behavior and performance of hydrologic models is an important aspect of understanding the underlying hydrologic systems. We argue that classical error measures...

Production of neutral species such as NOx(N, NO, and NO2) during particle-induced ionization events plays an important role in the chemistry of the mesosphere and lower...

This report presents absorption cross sections at temperatures of 293, 273, 253, 233, 213 and 203 K for the chlorofluorocarbon species CFC-11 (CC13F), CFC-12 (CC12F2), CFC-13...

Gerber (2007, hereafter Ge07) and Garrett (2007,hereafter Ga07) have written comments in reference to Heymsfield et al. (2006, hereafter H06). Dr. Gerber is the developer of the...

Observed surface air temperatures over the contiguous U.S. for the second half of the twentieth century showed a slight cooling over the southeastern part of the country, the...

This paper describes and evaluates physical parameterizations accounting for the effect of rooftop mitigation strategies (RMSs) on the urban environment, in the context of the...

Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere - the "global carbon budget"...

Ambient air pollution from ozone and fine particulate matter is associated with premature mortality. As emissions from one continent influence air quality over others, changes...

Energetic particle precipitation (EPP) causes ionization of the main constituents of the Earth's atmosphere which leads to the production of nitric oxide (NO) throughout the...

We describe a global atmospheric data assimilation scheme that has been adapted for use with a Martian General Circulation Model (GCM), with the ultimate goal of creating...

We study the variations of the topside ionospheric ion density measured by Defense Meteorological Satellite Program satellites during the intense magnetic storm on 7-10 November...

In 2006, NASA led a field campaign to investigate the factors that control the fate of African easterly waves (AEWs) moving westward into the tropical Atlantic Ocean. Aircraft...

Motivated by recent analysis of solar observations that show evidence of propagating Rossby waves in coronal holes and bright points, we compute the longitudinal phase...
