A method for determining intracloud lightning and ionospheric heights from VLF/LF electric field records
[1] The Los Alamos Sferic Array (LASA) recorded VLF/LF electric-field-change signals from over ten million lightning discharges during the period from 1998 to 2001. Using theExpand
Performance Assessment of the World Wide Lightning Location Network (WWLLN), Using the Los Alamos Sferic Array (LASA) as Ground Truth
Abstract The World Wide Lighting Location Network (WWLLN) locates lightning globally, using sparsely distributed very low frequency (VLF) detection stations. Due to WWLLN’s detection at VLF (in thisExpand
Observations of traveling ionospheric disturbances with a satellite-beacon radio interferometer : seasonal and local time behavior
We have operated a very long baseline interferometer array at a northern midlatitude site, illuminated by VHF radio beacons from two geosynchronous satellites, quasi-continuously for over a year. TheExpand
How do the strongest radio pulses from thunderstorms relate to lightning flashes
[1] We present a statistical analysis of thunderstorm radio frequency and optical data from the FORTE satellite to examine the relationship of strong radio frequency pulsed emissions to moreExpand
Comparison of Narrow Bipolar Events with Ordinary Lightning as Proxies for Severe Convection
Abstract Narrow bipolar events (NBEs) are a recently studied intracloud electrical-discharge process. It is speculated that an NBE is instigated by the extensive atmospheric shower of an energeticExpand
The blast wave of the Shuttle plume at ionospheric heights
The main engine burn (MEB) of the Space Shuttle deposits {approximately} 2 x 10{sup 12} joules of explosive energy and {approximately} 3 x 10{sup 5} kg of exhaust in almost horizontal flight atExpand
FORTE satellite constraints on ultrahigh energy cosmic particle fluxes
The FORTE (Fast On-orbit Recording of Transient Events) satellite records bursts of electromagnetic waves arising from near the Earth's surface in the radio frequency (rf) range of 30 to 300 MHz withExpand
Observations of ionospheric disturbances following a 5‐kt chemical explosion: 1. Persistent oscillation in the lower thermosphere after shock passage
We have observed a 6-min-period oscillation persisting for an hour in the ionospheric E region following a 5-kt chemical explosion on the ground 250 km south of the measurement site. TheExpand
Reduction of electron density in the night-time lower ionosphere in response to a thunderstorm
Tropospheric thunderstorms have been reported to disturb the lower ionosphere, at altitudes of 65–90 km. The use of lightning signals from a distant mesoscale storm to probe the lower ionosphereExpand
FORTE observations of lightning radio‐frequency signatures: Capabilities and basic results
The FORTE satellite, launched on August 29, 1997, carries both radio-frequency-receiver and optical (imaging and photometric) payloads for the study of lightning. The radio-frequency (RF) data forExpand
