The GRUAN station FMI-ARC in Sodankylä Finland organized an atmospheric sounding campaign in early 2010, which included participants from several countries. The first phase of the campaign was focussing on radiosonde inter-comparisons that were carried out in January-February 2010. Different commercial and research grade in situ instruments were launched with a focus on the comparison of humidity and temperature measurements in the troposphere and stratosphere.
The second GRUAN Implementation-Coordination Meeting (ICM-2) will take place in Payerne, Switzerland, from March 2-4, 2010.
