Abstract

Data were collected by Universities' Facility for Atmospheric Measurement's (UFAM) 1290mhz Degreane Mobile Wind Profiler, deployed at the Writtle Agriculture College, Essex, in August 2003 as part of the Tropospheric ORganic CHemistry Experiment Project (TORCH) 1 field campaign. During the field campaign the mobile wind profiler obtained vertical profiles of the horizontal and vertical wind components. For each signal beam profiles of the signal to noise (SNR) ratio and spectral widths were also taken. The data consist of files available in the NASA-AMES ASCII and netCDF binary formats and plots in PNG format. Data are available to all BADC registered users under the Government Open Data licence.
