Historical records of aviation turbulence encounters above Greenland are examined for the period from 2000 to 2006. These data identify an important flow regime that contributes...

The purpose of this study is to construct and analyze a long-term, continuous record of satellite ozone data to document such means and variabilities. This atlas presents...

Plasma outflows from the edges of active regions have been suggested as a possible source of the slow solar wind. Spectroscopic measurements show that these outflows have an...

Chemical modelling studies have been conducted over north-western Europe in summer conditions, showing that night-time dinitrogen pentoxide (N₂O₅) heterogeneous reactive uptake...

The concept of disjunct eddy sampling (DES) for use in measuring ecosystem-level micrometeorological fluxes is re-examined. The governing equations are discussed as well as...

Monitoring Earth's terrestrial water conditions is critically important to many hydrological applications such as global food production; assessing water resources...

A recently developed chemical ionization mass spectrometer for detecting neutral molecular clusters in the atmosphere (the Cluster-CIMS) is described. This instrument is unique...

The pineapple express (PE) phenomenon is responsible for producing extreme winter precipitation events on the west coast of the United States and Canada. We study regional...

Air pollution resulting from rapid urbanization and associated human activities in the Kathmandu Valley of Nepal has been leading to serious public health concerns over the past...

The scalability of computational applications on current and next generation supercomputers is increasingly limited by the cost of inter-process communication. We implement non-...

The Glimmer Community Ice Sheet Model (Glimmer-CISM) has been implemented in the Community Earth System Model (CESM). Glimmer-CISM is forced by a surface mass balance (SMB)...

In 2011, a significant drop in global sea level occurred that was unprecedented in the altimeter era and concurrent with an exceptionally strong La Niña. This analysis examines...

Observations from the SABER (Sounding of the Atmosphere using Broadband Emission Radiometry) instrument on the TIMED (Thermosphere, Ionosphere, Mesosphere, Energetics and...

A measurement and modeling campaign evaluated variations in tree temperatures with solar exposure at the edge of a forest clearing and how the resulting longwave radiation...

The Whole Atmosphere Community Climate Model (WACCM) is used to study the influence of gravity waves on the generation and evolution of an elevated stratopause following a...

Annual and monthly mean values of continental freshwater discharge into the oceans are estimated at 1° resolution using several methods. The most accurate estimate is based on...

Both the positive and negative phases of the North Atlantic Oscillation (NAO⁺ and NAO⁻, respectively) and atmospheric blocking in the Euro-Atlantic sector reflect synoptic...

The co-occurrence of heat waves and pollution events and the resulting high mortality rates emphasize the importance of the co-occurrence of pollution and temperature extremes....

Observations of chemical constituents and meteorological quantities obtained during the two Arctic phases of the airborne campaign ARCTAS (Arctic Research of the Composition of...

Airborne observations in deep stratiform and anvil clouds showed extensive layers of 10- to 40-kV/m electric fields colocated with highly stratified uniform radar reflectivity...
