ISB52: Doppler Lidar measurements from RAF Northolt and Malvern, UK
Abstract
This dataset contains Doppler lidar measurements from the ISB52 Improved Air Quality Forecasting project. The aim of the project was to develop a better understanding of air flow within the atmospheric boundary layer by gathering 3-dimensional air flow information using two identical Doppler lidars supplied by Qinetic and the University of Salford. The project compared parameters derived from the dual Doppler lidar measurements with inputs used in the UK Met Office air quality forecasting model. Field experiments were undertaken in March 2003 at Malvern and in July 2003 at RAF Northolt, West London, UK.
