is the web system that provides access to New Zealand's National Climate Database
The climate database holds data from about 6500 climate stations which have been operating for various periods since the earliest observations were made in the year 1850. The database continues to receive data from over 600 stations that are currently operating.
CliFlo returns raw data and statistical summaries. Raw data include ten minute, hourly and daily frequencies. Statistical data include about eighty different types of monthly and annual statistics and six types of thirty−year normals. See an example of daily output
and an example of statistical output
Hourly Data Sourced from MetService
The availabliity of hourly data from MetService through CliFlo changed on 01-Jan-2013 due to changes in the way that MetService and NIWA exchange and licence data.
Hourly data sourced from MetService with an observation date after 01-Jan-2013 are not available to the public. Hourly data sourced from MetService with an observation date before 01-Jan-2013 remain available to the public. (Note that MetService climate stations generally include "AWS" or "Aero" in the climate station name.) MetService hourly data remain in the Climate Database. If you want access to these MetService hourly data please email [email protected]
