Atmospheric retrievals from ACE are compared to nearly coincident measurements from HALOE. Comparisons are done for O 3 , HF, HCl, H 2 O, CH 4 , NO, NO 2 , and temperature. Statistics from 32 profile pairs that were reasonably close in space and time are presented. The temperature retrievals agree to within ±2 K, an important result as all other retrievals depend on this. ACE gas retrievals are typically higher than HALOE, with the exception of NO and NO 2 where HALOE is higher. This comparison helps provide traceability between two important complementary remote sensing missions, lends confidence to the initial ACE dataset, and provides a baseline for future retrieval improvements.
