News and Updates

We would like to to announce the official switchover of the WOUDC system, website and services to our updated platform on 13 May 2025. Over the past 24 months, the updated WOUDC website and API have been in public beta to allow for feedback and transition.

The WOUDC 1.x website and Web Services will be decommissioned on 13 May 2025.

We encourage all users to explore the beta website and API to familiarize themselves with the updates. Users are encouraged to provide feedback through the WOUDC email address.

The 1.30 release adds the ability to discover and access data from the European Brewer Network (EUBREWNET). Users can search EUBREWNET from the Data Search / Download page, and download resulting data directly from EUBREWNET. Note that downloading data from EUBREWNET requires authentication. Please see the EUBREWNET website for more information.

Users are encouraged to provide feedback through the WOUDC contact form.

The 1.28 release provides the following enhancements:

• added new and updated graphs leading up to 2019 for Ozonesonde plots, Total Ozone plots and UV index plots
• fixed the instrument selection dropdown in UV index plots to show graphs for the new Spectral instruments and other instruments under the UV radiation classification
• fixed the links to the Web Accessible Folder (WAF) in Dataset Information

Users are encouraged to provide feedback through the WOUDC contact form.

The 1.24 release provides the following enhancements:

• station profile pages provide a direct link to all data within a given station/instrument
• the Data Search / Download instrument list has been fixed to reset when changing countries

Users are encouraged to provide feedback through the WOUDC contact form.

The 1.22 release provides the following enhancements:

• the Data Search / Download page now includes filtering by country
• single stations pages now show station data holdings including data distributions and supported instruments
• data validator improvements performing additional metadata checking
• WMO WIGOS support for stations has been upgraded to version 1.0RC8

Users are encouraged to provide feedback through the WOUDC contact form.

As of 2018-02-21 WOUDC will transition from http to https protocol.

This change should not typically effect your use of WOUDC services, except that you should update your bookmarks and address references from http to https, for example, http://woudc.org becomes https://woudc.org. When accessing the website, http://woudc.org will be automatically forwarded to https://woudc.org, but we still recommend updating your bookmarks and references to https. Users accessing WOUDC data programmatically through Web services should manually update all their http address references to https.

Users are encouraged to provide feedback through the WOUDC contact form.
