Measurement activities

		The NILU Zeppelin observatory is located in the Arctic on Zeppelin Mountain, close to Ny-Ålesund, in the island archipelago of Svalbard. At 79° N, the station is located away from major pollutant sources. Influence from local pollutant sources, such as from the nearby community of Ny-Ålesund, is limited by the observatory’s location at 474 metres MSL, which means that most of the time it is above the local inversion layer. NILU conducts measurements of more than 20 greenhouse gases, including halogenated greenhouse gases, methane, CO2 (from 2011) and ozone.Longyearbyen 360 web cam, Ny-Ålesund web cam and weather forecast links for ZeppelinNRT CO, CH4, CO2 measured at Zeppelin

		R/V Helmer Hanssen (earlier R/V Jan Mayen) was designed by Skipsteknisk A/S and built at Danyard AS in 1988. R/V Helmer Hanssen is a stern trawler with a hull built to top ice class (DnV Ice 1A). Since June 17, 2011 R/V Helmer Hanssen has been owned by the University of Tromsø and Troms Offshore is responsible for the technical management and crewing of the ship. R/V Helmer Hanssen is a multipurpose vessel, designed for fishery and marine biological, geological and oceanographic surveys in open and ice covered waters (1-2 m drift ice), and specialises in acoustic surveying and bottom sediment sampling.Real-time location map Atmospheric measurements and lab at Helmer Hanssen

		The Facility of Airborne Atmospheric Measurements (FAAM) BAe-146 aircraft is a joint venture between the Met Office and UK Natural Environment Research Council (NERC), and operates as part of the UK National Centre for Atmospheric Sciences (NCAS) to provide an atmospheric instrument measurement platform. FAAM is also a member of the EUropean Facility for Airborne Research (EUFAR) fleet of research aircraft.

		The Airborne Extensive Regional Observations in SIBeria (YAK-AEROSIB) project is a bilateral cooperation coordinated by researchers from LSCE in France and IAO in Russia, involving teams from several laboratories in both countries, and active in several international collaborations. The objective of the YAK-AEROSIB project is to establish systematic aircraft-based observations of atmospheric concentrations in CO2, CH4, CO, O3 and aerosols over the interior of Eurasia. The current aircraft is a chartered Tupolev 134 with twin jet engines on the rear, with cruise speed of 850–900 km/h and a range of 1900–3000 km.
