Select Search Period

This screen allows you to specify the period for which you are intereseted in obtaining data for. The date range is defaulted to the most recently available three days worth of data, but you can change this if desired by over-riding the dates shown, or by choosing a date from the calendar lookup (by clicking on the button to the right of the date field). Once you have specified the period of interest, you can choose to view and download tables and plots of raw or summarised data. Raw data downloads are limited to a maximum of five years per request. The selectable period for data summary is limited to:
  • 30 years for monthly
  • 5 years for daily
  • 1 year for hourly
Missing data can accumultate within a selected period which may exceed 15% of all the data for that period. Any summarised data where 15% or more of the data is missing will return "missing" for that period, although raw data could be available for up to 85% of the data points for the period.
