3. Scientific Aims Polar ozone loss
Chemistry and dynamics of the UTLS, particularly in the tropics
leading to
a better understanding of ozone and UV radiation over mid-latitudes
ozone - climate interactions; predictive ability

4. International Satellite Validation
VINTERSOL extends planned activities:
ENVISAT - commissioning validation
time, species measured
ILAS 2
SAGE III - SOLVE 2
and provides additional validation for
GOME, ODIN, POAM.
