| Zusammenfassung |
| Results from a regional air quality forecast model, AIRPACT-3, were compared
to AIRS carbon monoxide column densities for the spring of 2010 over the
Pacific Northwest. AIRPACT-3 column densities showed high correlation
(R > 0.9) but were significantly biased (~25%)
with consistent under-predictions for spring months when there is significant
transport from Asia. The AIRPACT-3 CO bias relative to AIRS was eliminated
by incorporating dynamic boundary conditions derived from NCAR's MOZART
forecasts with assimilated MOPITT carbon monoxide. Changes in ozone-related
boundary conditions derived from MOZART forecasts are also discussed and
found to affect background levels by ± 10 ppb but not found to
significantly affect peak ozone surface concentrations. |
