Diagnosing regional sea level change over the altimeter era
Since 1993, satellite altimeters have been mapping sea level changes globally, revealing both the global mean rate and detailed patterns of regional variations. The global mean...- publication PDF

Prospects for seasonal prediction of summertime trans-Arctic sea ice path
The continuing decline of the summertime sea ice cover has reduced the sea ice path that must be traversed to Arctic destinations and through the Arctic between the Atlantic and...- publication PDF

Atmospheric implications of large C2-C5 alkane emissions from the U.S. oil...
Emissions of C-2-C-5 alkanes from the U.S. oil and gas sector have changed rapidly over the last decade. We use a nested GEOS-Chem simulation driven by updated 2011NEI emissions...- publication PDF

Evidence of spray-mediated air-sea enthalpy flux within tropical cyclones
It has long been conjectured that spray ejected from the high-wind ocean surface enhances air/sea enthalpy fluxes, but a lack of observational data, particularly at wind speeds...- publication PDF

Structure and dynamics of axisymmetric tornado-like vortices simulated with...
No-slip boundary conditions are often employed in idealized axisymmetric models to study tornadoes. These boundary conditions result in a poor representation of near-ground...- publication PDF

Development of satellite green vegetation fraction time series for use in...
A method is presented for development of satellite green vegetation fraction (GVF) time series for use in the Weather Research and Forecasting (WRF) model. The GVF data is in...- publication PDF

A unifying framework for metrics for aggregating the climate effect of...
Multi-gas approaches to climate change policies require a metric establishing 'equivalences' among emissions of various species. Climate scientists and economists have proposed...- publication PDF

Observations of thermosphere and ionosphere changes due to the dissipative...
In the current work, temperature and wind data from the Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) satellite during the years 2002-2007 were used to...- publication PDF

Dynamic pressure drag on rising buoyant thermals in a neutrally stable environment
This study examines dynamic pressure drag on rising dry buoyant thermals. A theoretical expression for drag coefficient C-d as a function of several other nondimensional...- publication PDF

Tropospheric ozone decrease due to the Mount Pinatubo eruption: Reduced...
We quantify the relationship between Mount Pinatubo eruption in June 1991 and tropospheric ozone abundances. The ozone reduction in the stratosphere and troposphere following...- publication PDF

Preindustrial to present-day changes in tropospheric hydroxyl radical and...
We have analysed time-slice simulations from 17 global models, participating in the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP), to explore changes...- publication PDF

An event study to provide validation of TING and CMIT geomagnetic...
The coupled thermosphere-ionosphere magnetosphere (CMIT) model and the Thermosphere Ionosphere Nested Grid (TING) model have been run to simulate the 15 May 1997 interplanetary...- publication PDF

Considerations on UAS-based in situ weather sensing in winter precipitation...
Freezing rain and freezing drizzle can produce nearly undetectable hazards, with potentially catastrophic consequences for aircraft within low altitudes (e.g., the terminal...- publication PDF

Semianalytical estimation of energy deposition in the ionosphere by...
For the first time we derive an analytical expression for energy deposition by propagating monochromatic Alfven waves in the collisional ionosphere-thermosphere (IT). Based on...- publication PDF

Land processes can substantially impact the mean climate state
Terrestrial processes influence the atmosphere by controlling land‐to‐atmosphere fluxes of energy, water, and carbon. Prior research has demonstrated that parameter...- publication PDF

Characterization of the long-term radiosonde temperature biases in the upper...
Radiosonde observations (RAOBs) have provided the only long-term global in situ temperature measurements in the troposphere and lower stratosphere since 1958. In this study, we...- publication PDF
