What kind of data do you want to download?


HOURLY OBSERVATIONS

Choose start and end dates for hourly observations and indexes. Requests are limited to 1,000 station × days (24,000 station-hours), so larger numbers of responding stations mean shorter periods of time can be requested. For example:

  • For the entire system, you can request up to 30 hours of data.
  • For all of MN (~185 stations) you can request about 5 days.
  • For a single station you can request just over 2.5 years of data.

These limitations are based on the number of matched stations and the duration of the request, regardless of whether a station actually has observations on all dates.

DAILY OBSERVATIONS

Choose start and end dates for daily observations and indexes. Requests are limited to 30,000 station × days, so larger numbers of responding stations mean shorter periods of time can be requested. For example:

  • For the entire system, you can just over a month.
  • For all of MN (~185 stations) you can request about 6 months.
  • To request an entire (>40 year) archive, we can only support 1 station at a time

These limitations are based on the number of matched stations and the duration of the request, regardless of whether a station actually has observations on all dates.

Come here often?

If you are using this download interface to regularly access small amounts of data, you can use our data API designed specifically for distributing observations and indices from GLFF. In fact, this interface itself just sends your request for data to the API!

We recommend using our GLFF API to download smaller and/or more frequent volumes of data programatically. This interface essentially creates API data requests for you, so check out the URL when you download your data to see how it works. Just create your own API key and then a token and you can request these data on your own.
