Water and energy budgets of hurricanes: Case studies of Ivan and Katrina
To explore the role of hurricanes in the climate system, a detailed analysis is made of the bulk atmospheric moisture budget of Ivan in September 2004 and Katrina in August 2005...- publication PDF

Signatures of thermospheric-exospheric coupling of hydrogen in observed...
Analysis of an established geocoronal H α data set indicates a seasonal trend in observed dusk-to-dawn intensity variation, consistent with a diurnal variation in the...- publication PDF

The product and system specificities of measuring curation impact
Using three datasets archived at the National Center for Atmospheric Research (NCAR), we describe the creation of a 'data usage index' for curation-specific impact assessments....- publication PDF

A path toward short-term probabilistic flash flood prediction
There are ongoing efforts to move beyond the current paradigm of using deter-ministic products driven by observation-only data to make binary warning decisions. Recent works...- publication PDF

Reduced biomass burning emissions reconcile conflicting estimates of the...
Several viable but conflicting explanations have been proposed to explain the recent similar to 8 p.p.b. per year increase in atmospheric methane after 2006, equivalent to net...- publication PDF

Extension of the MURaM radiative MHD code for coronal simulations
We present a new version of the MURaM radiative magnetohydrodynamics (MHD) code that allows for simulations spanning from the upper convection zone into the solar corona. We...- publication PDF

The impact of stochastic physics on tropical rainfall variability in global...
Many global atmospheric models have too little precipitation variability in the tropics on daily to weekly time scales and also a poor representation of tropical precipitation...- publication PDF

17 O-excess in tropical cyclones reflects local rain re-evaporation more...
O-17-excess is a relatively new water isotope parameter that could potentially provide useful information about the hydrological cycle. Previous works focusing on O-17-excess in...- publication PDF

Obtaining single path phase delays from GPS double differences
We describe a method for obtaining single-path phase delays from GPS double differences. The resulting "zero differences" (ZDs) can be used for remote sensing of atmospheric...- publication PDF
