also be used in the validation of NO2 profile measurements made by satellite instruments. about 10 K warmer than those over Antarctica, pre-venting the formation of polar stratospheric clouds (PSCs), which are required for the catalytic cycles that destroy O3. In addition, the northern polar vortex is served over the Arctic. Springtime polar O3 loss is well accepted as resulting from chlorine activation on PSCs and subsequent catalytic photochemical reactions. Al-though atmospheric chlorine loading is believed to have reached its maximum or to be already declining, the cause of the recent observed decrease in stratospheric temperatures in the Arctic is still not clear. One theory is
