British Antarctic Survey (BAS) is collecting radiosonde data that were produced during YOPP Southern Hemisphere Special Observing Period (SOP). These data are stored on a FTP server by BAS which is available at ftp://ftp.bas.ac.uk/src/YOPP-SH/radiosondes/.

Following an upgrade of the front- and backend services of the catalogue, the catalogue search engine was restructured yesterday and reindexing of datasets initiated. During the evening of November 21 a hardware outage prevented completion of the reindexing process. Due to this, the catalogue is yet not properly populated. This work will continue once hardware issues have been fixed.

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.
