Solar magnetic activity exhibits variations with periods between 1.5 and 4 years, the so-called quasi-biennial oscillations (QBOs), in addition to the well-known 11-year Schwabe...

A widely recognized issue found in most Earth System Models is that of convective precipitation being triggered too early during the day over land, often resulting in persistent...

The regional distributions of black carbon aerosol ( soot) are calculated and the impacts of black carbon aerosol on photolysis frequencies and ozone concentrations are...

The emerging field of extreme-event attribution (EEA) seeks to answer the question: "Has climate change influenced the frequency, likelihood, and/or severity of individual...

The Pliocene epoch has great potential to improve our understanding of the long-term climatic and environmental consequences of an atmospheric CO2 concentration near similar to...

Whether radar meteor echoes occur at high altitudes (above ~130 km) in the Earth's atmosphere is a long-standing question within the meteor radar community. Using observations...

Inclusion of fundamental ecological interactions between carbon and nitrogen cycles in the land component of an atmosphere-ocean general circulation model (AOGCM) leads to...

A detailed observational and Weather Research and Forecasting (WRF) model analysis utilizing Weather Surveillance Radar-1988 Doppler (WSR-88D), surface, and upper-air...

A unique dataset consisting of high-resolution polarimetric radar measurements and dense rain gauge and disdrometer observations collected in east-central Florida during the...

With the resolution of global numerical weather prediction (NWP) models now typically between 10 and 20 km, forecasts are able to capture the evolution of synoptic features that...

The report on the Central Pacific VLF Signal Survey and Omega Wind Error Predictions is a preliminary document based on the theoretical predictions of Omega signal strengths and...

Under-catch errors in precipitation gauge records can be as large as 50-100% during the cold season at high latitudes. To quantify the impacts of these errors on...

Rhodoliths are nodules of non-geniculate coralline algae that occur in shallow waters (<150 m depth) subjected to episodic disturbance. Rhodolith beds stand with kelp beds,...

Terrestrial auroras are highly structured that visualize the perturbations of energetic particles and electromagnetic fields in Earth's space environments. However, the...

Whole Atmosphere Community Climate Model (WACCM) simulations are used to investigate the migrating and nonmigrating tidal variability in the mesosphere and lower thermosphere...

A variant of a least squares ensemble (Kalman) filter that is suitable for implementation on parallel architectures is presented. This parallel ensemble filter produces results...

Forecasting the carbon uptake potential of terrestrial ecosystems in the face of future climate change has proven challenging. Process models, which have been increasingly used...

We extend a stochastic aerosol-snow albedo model to explicitly simulate dust internally/externally mixed with snow grains of different shapes and for the first time quantify the...

After nearly three decades of observed increasing trends of Antarctic sea ice extent, in September-October-November 2016, there was a dramatic decrease. Here we document factors...

Observations from lidars and satellites have shown that large neutral temperature increases and decreases occur in the middle and low latitudes of the mesosphere and lower...
