| Zusammenfassung |
| The Measurements of Pollution in the Troposphere (MOPITT) Version 6 (V6) product for carbon monoxide (CO) incorporates
several enhancements which will benefit many users of MOPITT data. V6
algorithm improvements are described in detail, and V6 validation results are
presented. First, a geolocation bias related to the orientation of the MOPITT
instrument relative to the TERRA platform was characterized and eliminated.
Second, the variable a priori for CO concentrations for V6 is based on
simulations performed with the chemical transport model Community Atmosphere Model with Chemistry (CAM-chem) for the
years 2000–2009 instead of the model-derived climatology for 1997–2004 used
for V5. Third, meteorological fields required for V6 retrieval processing are
extracted from the MERRA (Modern-Era Retrospective Analysis For Research
And Applications) reanalysis. Finally, a significant latitude-dependent
retrieval bias in the upper troposphere in Version 5 products has been
substantially reduced. |
