This note assesses the improvements in dual-Doppler wind syntheses by employing a multipass Barnes objective analysis in the interpolation of radial velocities to a Cartesian...

We analyse historical (1850–2014) atmospheric hydroxyl (OH) and methane lifetime data from Coupled Model Intercomparison Project Phase 6 (CMIP6)/Aerosols and Chemistry Model...

Thermospheric wind observations from high to mid latitudes are compared with the newly developed Multiscale Atmosphere Geospace Environment (MAGE) model for the Nov 3-4...

Global climate models that do not include interactive middle atmosphere chemistry, such as most of those contributing to the Coupled Model Intercomparison Project Phase 5,...

The Saharan Air Layer (SAL) is a dominant feature that influences the large-scale environment from West Africa to the western tropical North Atlantic. While the SAL can create...

The use of ensemble filters for estimating sources and sinks of carbon dioxide (CO₂) is becoming increasingly common, because they provide a relatively computationally...

Since January 2009, two long-range high-frequency (HF) radar systems have been collecting hourly high-spatial-resolution surface current data in the southeastern corner of the...

The IIASA gridded population downscaling methodology is one of only a few existing models for constructing spatially explicit global population scenarios. Furthermore, this...

The Chronopolis Digital Preservation Initiative, one of the Library of Congress' latest efforts to collect and preserve at- risk digital information, has completed its first...

Global convection-permitting models enable weather prediction from local to planetary scales and are therefore often expected to transform the weather prediction enterprise....

This article does not have an abstract or article summary.

Specified dynamics schemes are ubiquitous modeling tools for isolating the roles of dynamics and transport on chemical weather and climate. They typically constrain the...

This study focuses on the evaluation of 3-hourly, 0.25° × .25°, satellite-based precipitation products: the Tropical Rainfall Measuring Mission (TRMM) Multisatellite...

We demonstrate that the global cooling resulting from a range of nuclear conflict scenarios would temporarily increase the pH in the surface ocean by up to 0.06 units over a...

A group under Dr. Luis Alvarez at the Space Sciences Laboratory, University of California, is preparing a balloon-borne particle physics experiment, designed for recovery at...

This paper discusses large-scale climate variability for several marine ecosystems and suggests types of ecosystem responses to climate change. Our analysis of observations and...

The NCAR Whole Atmosphere Community Climate Model, with a quasi-uniform horizontal resolution of similar to 25 km and a vertical resolution of 0.1 scale height, produces large...

The effects of the tropical Pacific El Niño Southern Oscillation (ENSO) phenomenon are communicated to the rest of the globe via atmospheric teleconnections. Traditionally,...

Ensemble simulations are run with a global coupled climate model employing five forcing agents that influence the time evolution of globally averaged surface air temperature...

Motivated by observed anomalous features in cycle 23, as inferred from records of photospheric magnetic flux, we develop a flux transport dynamo-based scheme in order to...
