OTHER_COMMENTS: Final Data. Future modifications to the calibration are possible but unlikely.
- Calibrating ATHOS with the new OH-removing inlet (OHSI) has been difficult, particularly for low pressure (high altitude).
- The ATHOS HOx calibrations are pressure-dependent, changing a factor of 3-5 over the atmospheric pressure range.
- The laboratory calibration uses different inlet hole sizes to simulate atmospheric pressure changes.
- For 2 years, we tried various calibration approaches with the OHSI in place, but none gave repeatable results for high altitude measurements.
- In the laboratory calibrations, it proved to be impossible to simulate the atmospheric airflow with the OHSI on and the smaller inlet sizes.
- In the end, we found that our previous calibration method gave the most repeatable and reliable results.
- In-flight diagnostics show that OH loss on the OHSI is negligible.
