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.
