. Hydroxyl (OH) short-wave infrared emissions arising from OH(4-2, 5-2,8-5, 9-6) as measured by channel 6 of the SCanning Imaging AbsorptionspectroMeter for Atmospheric CHartographY (SCIAMACHY) are used toderive concentrations of OH(v=4, 5, 8, and 9) between 80 and96 km. Retrieved concentrations are used to simulate OH(5-3,4-2) integrated radiances at 1.6 µm and OH(9-7, 8-6) at2.0 µm as measured by the Sounding of the Atmosphere usingBroadband Emission Radiometry (SABER) instrument, which are not fullycovered by the spectral range of SCIAMACHY measurements. On average,SABER “unfiltered” data are on the order of 40 % at1.6 µm and 20 % at 2.0 µm larger thanthe simulations using SCIAMACHY data. “Unfiltered” SABER data area product, which accounts for the shape, width, and transmission ofthe instrument's broadband filters, which do not cover the fullro-vibrational bands of the corresponding OH transitions. It is foundthat the discrepancy between SCIAMACHY and SABER data can be reducedby up to 50 %, if the filtering process is carried outmanually using published SABER interference filter characteristics andthe latest Einstein coefficients from the HITRAN database. Remainingdifferences are discussed with regard to model parameter uncertaintiesand radiometric calibration.
