Making best use of collected weather observations is simplified where thought is given to record management and storage: gathering meteorological records is usually a means to an end, rather than an end in itself. The more effectively records are stored, the quicker and easier it becomes to analyse and use them productively – a statement which applies equally to both professional and amateur observers. This chapter provides tried and tested suggestions for collecting, storing and archiving data from both manual observations and automatic weather stations (AWSs).
