Abstract

The Shoeburyness Field Trial: Investigation of Meteorological Effects on the Sound Propagation from a Helicopter Operating Near a Land Sea Interface Project was a QinetiQ applied research programme 3G23, funded by Ministry of Defence (MOD). The project duration was from April 2004 to March 2007 and had the aim to investigate noise modelling of helicopters with regard to long range sound propagation. The trial sought to understand more fully the meteorological effects on sound propagation over a land sea interface.

This dataset collection contains measurements from the Universities Facility for Atmospheric Measurement (UFAM) Doppler lidar system, which was used to obtain profiles of the radial velocity to determine turbulence measurements at points along the aircraft flight path.
