Description

This data gives a historical record of the weather in Stirling (central Scotland). To be exact, the data is from an Oregon Scientific Professional Weather Station (model WMR928) on the roof of the author's house in nearby Bridge of Allan. The true data starts from 3rd April 2003; fictitious data has been created for 1st January to 2nd April 2003 to make up a whole year. You can see the current data on the Stirling Weather History web page. The data is packaged up roughly annually and made available in bulk through this download. The last day currently provided is indicated by the History below.

Usage

Each day's data is logged every 15 minutes to a file named nn.dat.gz. This is placed in the directory yyyy/mm. The file contains the following fields separated by one or more spaces. Values are calculated for each logging interval, except rainfall which is totalled since midnight. Each interval generates a line as follows in the log file. The numbers refer to fields, counting from 0 as the start.
