Wednesday 21th November, maintenance is planned in the computer halls hosting the services. This will start 12:30 CET and may last for 2.5 hours. During this period services may not be available. In addition the search engine will be rebuilt this day. This may cause interruptions throughout the day.

An interactive service that can be used to validate NetCDF/CF and ACDD files have been added to the Support section. This is available through https://yopp.met.no/dataset_validation/form.

This weekend the YOPP Data Portal backends were updated to take advantage of a number of improvements in the search interface. In this process,  synoptic weather station information extracted from WMO GTS have been added to the catalogue. These stations are normally presented as time series at stations. The search interface now allows plotting and transformation of these data on the fly. As this is a net centric service, beware that depending on the network traffic and the response time of the contributing data centres web services this may take some seconds.

The backend system for the YOPP Data Portal has been upgraded. In order to utilise the new functionality available, discovery metadata have to be reingested. This will be done June 20-29. Irregular behaviour may occur during this period.
