Quality Assessment
All data have been compared with the current Harmonic Constants library, and residuals checked. Records have been visually inspected for spikes, datum shifts and timing errors.
Where there are problems with the primary channel, data may be available from the backup channel. Please contact enquiries@bodc.ac.uk for more information.
On 24/02/2012 a new data logger was installed. Tests were carried out to ensure the logger was functioning correctly, resulting in some data being lost.
