Feasibility of an airborne TV camera as a size spectrometer for cloud droplets in daylight
Read more of: Feasibility of an airborne TV camera as a size spectrometer for cloud droplets in daylightPhotographs of clouds taken with a camera with a large aperture ratio must have a short depth of focus to resolve small droplets. Hence the sampling volume is small, which […]

Slant column measurements of O3 and NO2 during the NDSC intercomparison of zenith-sky UV-visible spectrometers in June 1996
Read more of: Slant column measurements of O3 and NO2 during the NDSC intercomparison of zenith-sky UV-visible spectrometers in June 1996In June 1996, 16 UV-visible sensors from 11 institutes measured spectra of the zenith sky for more than 10 days. Spectra were analysed in real-time to determine slant column amounts […]

Regular patterns in frictional resistance of ice-stream beds seen by surface data inversion
Read more of: Regular patterns in frictional resistance of ice-stream beds seen by surface data inversionFast-flowing glaciers and ice streams are pathways for ice discharge from the interior of the Antarctic Ice Sheet to ice shelves, at rates controlled by conditions at the ice-bed interface. […]

VLF scattering from red sprites: Vertical columns of ionization in the Earth-ionosphere waveguide
Read more of: VLF scattering from red sprites: Vertical columns of ionization in the Earth-ionosphere waveguideRed sprites were discovered by chance in 1989 when a low-light TV system was pointed above an active thunderstorm. Optically, they are observed as clusters of short-lived (∼50 ms) pinkish-red […]

Magnetospheric line radiation observations at Halley, Antarctica
Read more of: Magnetospheric line radiation observations at Halley, AntarcticaMagnetospheric line Radiation (MLR) events are relatively narrowband VLF signals that sometimes drift in frequency, and have been observed in both ground based and satellite data sets. Line radiation has […]

Modeling of subionospheric VLF signal perturbations associated with earthquakes
Read more of: Modeling of subionospheric VLF signal perturbations associated with earthquakesIt has been reported that propagation of very low frequency (VLF) waves in the Earthionosphere waveguide might provide an indication of imminent earthquakes [Hayakawa et al., 1996; Molchanov et al., […]

VLF scattering from red sprites: Application of numerical modeling
Read more of: VLF scattering from red sprites: Application of numerical modelingRed sprites were discovered by chance in 1989 when a low-light TV system was pointed above an active thunderstorm. Red sprites are associated with columns of ionization in the Earth-ionosphere […]

Red sprites, upward lightning, and VLF perturbations
Read more of: Red sprites, upward lightning, and VLF perturbationsIn the last decade there has been a great deal of interest in the detection and understanding of phenomena occurring above active thunderstorms. The discovery of the optical phenomena now […]

Riometer and HF radar signatures of polar patches
Read more of: Riometer and HF radar signatures of polar patchesPolar patch was the name given originally to a spatially limited enhancement of the 630-nm emission observed in the dark polar cap. More recently, the term has been applied to […]
