Web Services

We provide our data to customers who want to use it in their own applications. These services enable manual or automated machine-to-machine data, model, and product retrievals. Data can be downloaded in multiple formats, such as CSV, XML, KML, NetCDF, JSON, TXT, and DODS.

To prevent numerous large data requests slowing data access through the internet services; all internet data services have limits on the amount of data which can be retrieved per request. These limits are based on the interval of data requested.

  • 6-Minute Interval data is limited to 1 month of data
  • Hourly Interval data is limited to 1 year of data
  • High/Low data is limited to 1 year of data
  • Monthly Means data is limited to 200 years
