This study reports a special case of the propagation and morphology of medium scale traveling ionospheric disturbances (MSTIDs) over middle-latitude China on the night of August...

A difference-frequency generation based spectrometer system for simultaneous ultra-sensitive measurements of formaldehyde (CH₂O) and Methane (CH₄) is presented. A new...

In the subalpine zone of the Rocky Mountains, climate change is predicted to result in an increase in the frequency and severity of spruce beetle outbreaks. Climate change...

During the Atlanta ANARChE Study of July and August 2002, atmospheric aerosol size distributions from 3 to 2000 nm were measured continuously with 5-min resolution. Sulfuric...

Despite offsetting global mean surface temperature, various studies demonstrated that stratospheric aerosol injection (SAI) could influence the recovery of stratospheric ozone...

Atmospheric intraseasonal variability in the tropical Atlantic is analyzed using satellite winds, outgoing longwave radiation (OLR), and reanalysis products during 2000-08. The...

Microphysical properties of cirrus clouds largely influence their atmospheric radiative forcing. However, uncertainties remain in simulating/parameterizing the evolution of ice...

Trailing cone results verify that pressure corrections for the NCAR Sabreliner derived from tower flyby data can be extrapolated to higher Mach numbers and higher altitudes with...

The relative importance of wildfire smoke for air quality over the western US is expected to increase as the climate warms and anthropogenic emissions decline. We report on in...

Internal tides have a pivotal role in the climate system as a primary source of mechanical energy for diapycnal mixing, which sustains the global meridional overturning...

This study examines the spatial variability of ozone fluxes over flat heterogeneous terrain consisting of a patchwork of irrigated and nonirrigated surfaces. Fluxes of ozone and...

Ground-level ozone (O 3 ) pollution is a persistent environmental concern, even in regions that have made efforts to reduce emissions. This study focuses on the state of...

The Madden-Julian Oscillation (MJO) is a dominant source of subseasonal atmospheric variability in the tropics and significantly impacts global weather and climate...

This study uses an atmosphere-ocean fully coupled climate model to investigate possible remote impacts of Asian carbonaceous aerosols on US climate change. We took a 21st...

Accurate three-dimensional information of wind flow fields can be an important tool in not only visualizing complex flow but also understanding the underlying physical processes...

An updated assessment of uncertainties in "observed" climatological winds and temperatures in the middle atmosphere (over altitudes ~10-80 km) is provided by detailed...

Atmospheric ice particles exist in a variety of shapes and sizes. Single hexagonal crystals like common hexagonal plates and columns are possible, but more frequently,...

The identification and mitigation of anomalous propagation (AP) and normal propagation (NP) ground clutter is an ongoing problem in radar meteorology. Scatter from ground-...

Numerical solutions of the incompressible magnetohydrodynamic (MHD) equations are reported for the interior of a rotating, perfectly-conducting, rigid spherical shell that is...

A cloud system-resolving model (the Weather Research and Forecasting model) with 1 km horizontal grid spacing is used to investigate the response of an idealized supercell storm...
