Structure of the AQA Weather Data Set

The AQA large data set is typically provided as a multi-sheet spreadsheet. Each sheet corresponds to a different weather station or a different time period. The data set is structured with:

• Columns representing different weather variables
• Headers at the top of each column giving the variable name and/or units
