DMI’s APIs and Bulk Download Services for retrieval of data

When using DMI’s data for development of applications for mobile units, continuous updating of the application with data via DMI’s web service must be avoided. Applications for mobile units may not update with data via DMI’s web services when the application is not active. 

DMI’s web services are placed on a platform which is designed to support many users at the same time. At the same time, quick response times are expected.  However, you share DMI’s web services with many users, and you may therefore experience variations in the response time and capacity.

DMI reserves the right to set up detailed terms in relation to “fair use” (i.e. normal and reasonable use) of DMI’s open data services, including the right to adjust the bandwidth for individual IP addresses if these strain DMI’s services to a disproportionately wide extent.

DMI reserves the right to suspend a user’s API key if these terms are breached.

  • If data are used in a raw, quoted or recognisable form in text and graphic products: “Source: DMI”.
  • If data are used as input in further data processing: “Based on data from DMI and subsequently processed”.
  • To ensure that “DMI” appears as the source on the front page of the service if other sources are also mentioned on the front page.
  • Time when the data were retrieved from DMI.
