Validation of Aura MLS HO_x measurements with remote-sensing balloon instruments. Geophysical Research Letters 33: doi: 10.1029/2005GL024048. issn: 0094-8276.

Satellite measurements of OH and HO2 obtained by the Aura MLS instrument are compared to the balloon-borne BOH and FIRS-2 instruments. All measurements are also compared with constrained photochemical model calculations. On average, both balloon measurements of OH agree with MLS within 17% over 25--40 km and the measurements agree with the model within 12%. The three measurements for column of OH above 40 km agree within 8% and the mean is 12% below the model. Measurements of HO2 from FIRS-2 and MLS agree on average within 23% over 25--40 km and the differences are generally within the experimental precision. The HO2 measurements agree with the model within 14%. Measurements of HO2 for the column over 40--60 km agree within 16% and the mean measured column agrees with the model within the experimental precision. Our observations do not appear to indicate a "HOx dilemma."
