General Aviation (GA) accident statistics indicate that visual flight rules (VFR) flight into instrument meteorological conditions (IMC) is a major safety hazard within general aviation. Little research has been conducted to identify the factors that influence VFR pilots’ decisions to risk flying into deteriorating weather. As accident reports provide a naturalistic source of such information, ...

The wet bulb globe temperature index (WBGT) is a common method to assess the environmental contribution to heat stress as part of an occupational exposure assessment. The two purposes of this study were (1) to compare empirical relationships of some meteorological conditions to WBGT, and (2) to evaluate a smaller globe and alternative method to assess natural wet bulb using a relative humidity ...

Satellite observation of Earth's atmosphere in the millimetre and sub-millimetre wavelength region is complementary to those in the visible and infrared spectral region. The emission and opacity of the atmosphere, and scattering by ice particles are all exploited for sensing various layers of the atmosphere in terms of water vapour content, temperature, molecular composition, precipitating wate...

This paper elaborates on the rationale behind the proposed standard limits for the accuracy of rainfall intensity measurements obtained from tipping-bucket and other types of rain gauges. Indeed, based on experimental results obtained in the course of international instrument Intercomparison initiatives and specific laboratory tests, it is shown here that the accuracy of operational rain gauges...

The experimental design and instrumentation for an integrated shallow-water surface gravity wave experiment is discussed. The experiment required the measurement of the water surface elevation, meteorological parameters, and directional spectra at a number of locations on a shallow lake. In addition, to acquire data under a wide range of conditions, an experimental period of three years was req...

A simple, classical, and expedient method for the retrieval of atmospheric pressuretemperature profiles has been applied to the high-resolution infrared solar absorption spectra obtained with the Atmospheric ‘I’race Molecule Spectroscopy (ATMOS) instrument. The basis for this method is a rotational analysis of retrieved apparent abundances from COZ rovibrational absorption lines, employing exis...
