Ozone (O 3 ) measurements made with the Improved Limb Atmospheric Spectrometer (ILAS) onboard the Advanced Earth Observing Satellite (ADEOS) were validated with correlative ozonesonde measurements conducted at five stations, Andoya, Kiruna and Yakutsk in the Northern Hemisphere, and Neumayer and Syowa in the Southern Hemisphere. The ILAS Version 3.10 O 3 vertical profiles were compared with 79 correlative ozonesonde measurements that were made within 500 km and 3 hours in distance and time differences, respectively. The comparisons indicate that ILAS O 3 typically has an accuracy within 20% between 12 and 35 km. The precision of the ILAS O 3 is estimated to be ±10–25% between 12 and 20 km, ±5–7% between 20 and 30 km, and ±5% between 30 and 40 km.
