Arctic Summer Special Observing Period (1 July to 30 September 2018)

Extra Radiosonde Launches from Arctic Meteorological Stations

At the AWIPEV research base in Ny-Alesund, Svalbard, radiosonde activities were increased to 4 launches per day during SOP2. Vaisala RS41 sondes were scheduled at launch times 5, 11, 17, and 23 UTC. The AWIPEV station is registered as WMO radiosonde station 01004, and data transmission to GTS occurs via MET Norway.

Different people haven been at the station to take care of the extra soundings.

Extra Radiosonde Launches from Research Vessels

In August and September 2018, the Swedish research icebreaker Oden went to the Arctic Ocean to drift with an ice flow for several weeks. Onboard the vessel, the YOPP-endorsed project 'Arctic Climate Across Scales' (ACAS) launched extra radiosondes as a contribution to the second YOPP Special Observing Period. PI of the project Michael Tjernström (Stockholm University) has shared regular posts and photos from the expedition.
