1.Observation of ozone profiles in the arctic summer stratosphere was carried out at Ny Alesund in Spitzbergen, Norway in 1995 using an optical ozone sensor on board a BT-5 high altitude balloon.Two personnels were sent to the site for this observation.Four launches were as follows and good data were obtained for each launch.
'ECC on board' means ECC was on the same balloon to make a comparative measurements and 'ECC on rubber balloon' means concurrent launch of ECC with a rubber balloon.
2.Ground observation of ozone chemistry related atmospheric minor constituents ; HCl, HF,HNO_3, O_3, ClONO_2, CH_4 and N_2O in the arctic winter was made at Kimura, Sweden in March 1996 with a FTIR.One personnel was sent to the site.
3.Results from observations in the arctic, except for the ground observation at Kiruna whose data have not been processed yet, have been examined as follows :
(1) Comparison of ozone profiles obtained with an optical sensor and an ECC ozonesonde showed that both profiles agree well each other below 30km and that a distinct structure around 40km was seen in the optically obtained profile while ECC profile above 30km decreases monotonically with altitude.This indicates that ozone profiles can be obtained with the optical method even above 40km while ECC becomes unreliable due to its low pumping efficiency in high altitudes.
(2) Ozone profiles up to the upper stratosphere in the arctic have been obtained in two summers including 1995.
