We analyze the contribution of North American (NA) lightning and anthropogenic emissions to ozone concentrations, radiative forcing, and export fluxes from North America during...

Temperature observations of the upper-air atmosphere are now available for more than 40 years from both ground- and satellite-based observing systems. Recent years have seen...

A climate model (Community Earth System Model with the Community Atmosphere Model version 5 (CESM-CAM5)) is used to identify processes controlling Southern Ocean (30-70°S)...

SPHEREPACK 2.0 is a collection of FORTRAN programs that facilitates computer modeling of geophysical processes. The package contains programs for computing certain common...

A closed total energy (TE) budget is of utmost importance in coupled climate system modeling; in particular, the dynamical core or physics-dynamics coupling should ideally not...

A novel approach, using low Earth orbit (LEO) satellite microwave communication links for cloud liquid water measurements, is proposed in this paper. The feasibility of this...

This Technical Note was prepared during the author's year-long research stay at NCAR's Atmospheric Technology Division (ATD). It is a translated, revised and slightly extended...

The active 2020 Atlantic hurricane season produced 30 named storms, 14 hurricanes, and 7 major hurricanes (category 3+ on the Saffir–Simpson hurricane wind scale). Though the...

The purpose of this technical note is to describe and demonstrate the capabilities of a processor (VERIFY) developed to verify objectively forecasts generated by the PSU/NCAR...

This article does not have an abstract or article summary.

This study reports the long-term variability and tendencies in important non-migrating (DE3, DW2, DW3) and stationary (DS0) diurnal tides using a three-member ensemble of...

For the period of 1990 to 2000, atmospheric particulate mass concentrations have decreased in Central Europe. Simultaneously, the amount of shortwave radiation reaching the...

The performance of the spectral wind wave model SWAN in tidal inlet seas was assessed on the basis of extensive wave measurements conducted in the Amelander Zeegat tidal inlet...

The Measurements of Pollution in the Troposphere (MOPITT) retrievals over urban regions have not been validated systematically, even though MOPITT observations are widely used...

Historical understanding of marine biological dynamics has been limited by sparse in situ observations and the fact that dedicated ocean color satellite remote sensing only...

We use the Whole Atmosphere Community Climate Model, coupled to a deep ocean model, to investigate the impact of continued growth of halogenated ozone depleting substances (ODS)...

This paper reports the characteristics of the topside ionospheric O+ diffusive flux (phi O+) during both geomagnetically quiet (0 <= Kp <= 2) and moderate (2 < Kp <=...

Low cloud ceilings and poor visibility claim the lives of more general aviation (GA) pilots and passengers than any other cause of weather-related GA accidents. Experience shows...

This report outlines the structure of and summarizes the recommendations made at the Fifth International Conference on Reanalysis (ICR5), attended by 259 participants from 37...

Initialization of the hurricane vortex in weather prediction models is vital to intensity forecasts out to at least 48 h. Airborne Doppler radar (ADR) data have sufficiently...
