Long Term

Darker blue shaded areas on long term data indicate maximum and minimum levels for the date (you may need to zoom in closer to see them).

Long term data may have gaps where the API data was not available.

Note: CSV data will include any outlying values that have been ignored by our graphing system as probably erroneous (eg, because they are ridiculously high compared to the values either side of them). It is your responsibility to filter these out if necessary.

Important! If you are planning to retrieve the csv data automatically, you must read and understand the limitations on the data and its availability.
