| Zusammenfassung |
| Ozone measurements from ozonesondes, AROTAL, DIAL, and POAM III
instruments during the SOLVE-2/VINTERSOL period are composited in a
time-varying, flow-following quasi-conservative (PV-θ)
coordinate space; the resulting composites from each instrument are
mapped onto the other instruments' locations and times. The mapped
data are then used to intercompare data from the different instruments.
Overall, the four ozone data sets are found to be in good agreement. AROTAL
shows somewhat lower values below 16 km, and DIAL has a positive bias
at the upper limits of its altitude range. These intercomparisons are
consistent with those obtained from more conventional near-coincident
profiles, where available. Although the PV-θ mapping technique
entails larger uncertainties of individual profile differences
compared to direct near-coincident comparisons, the ability to include
much larger numbers of comparisons can make this technique
advantageous. |
