ECC ozone sonde - the ozone sonde observations of atmospheric ozone profiles at Salekhard aerological station are carried out since 1997. Currently, we use 2Z-ECC ozone sondes for ozone profile observations in the winter-spring period. The results of ozonesounding at Salekhard station are in the NDACC database. In December 2013 and January 2014 we plan to upgrade this ozonesounding station with the iMet-1 radiosonde and ECC 2Z-V7 ozone sonde. This type of ozone sonde will be used in the winter-spring season of 2014.
