[1] Using recently published electron phase space densities (PSD) as a function of L* (L* is approximately the radial distance in Earth radii at the equator) and time, energization and loss in the Earth’s outer electron radiation belt were studied quantitatively and numerically using a radial diffusion model that included finite electron lifetimes and an internal source parameterized as a funct...

We present a preliminary analysis of the spatial and seasonal lightning distribution near the Cerro Chascón science preserve, probed with a space-borne imaging sensor and groundbased storm detectors. The lightning flash rate in this area is among the lowest in the world for comparable latitudes. Thunderstorms only occur around 5 days per year. Most observed lightning strikes occurred far to the...

ne of the most unexpected new applications for wide swath synthetic aperture radar (SAR) is the monitoring of atmospheric expressions of storms over the ocean. SAR has an advantage over many sensors because it can pass through clouds and take images at any time of day. However, since SAR’s detection capability is based on the modulation of the sea surface wind field, it can only observe storms ...

Probabilistic quantitative precipitation forecasts challenge meteorologists due to the wide variability of precipitation amounts over small areas and their dependence on conditions at multiple spatial and temporal scales. Ensembles of convection-allowing numerical weather prediction models offer a way to produce improved precipitation forecasts and estimates of the forecast uncertainty. Thesemo...

The validity of a technique developed by the authors to identify historical occurrences of intense geomagnetic storms, which is based on finding approximately coincident observations of sunspots and aurorae recorded in East Asian histories, is corroborated using more modern sunspot and auroral observations. Scientific observations of aurorae in Japan during the interval 1957–2004 are used to id...

Dust storms have impacts on both human and physical environments, associated with an increase in atmospheric particulate matter (PM) concentrations. Most studies on exposure to PM have focused on the outdoor air, while information on indoor pollution, is still lacking. The aim of this study was to examine the impact of desert dust events on PM concentrations in indoor environments. A total of o...
