Aura MLS Documentation
Version 6 Data Quality
Documents / Publications
Data Processing Information Tables
| MLS Version | Major Change |
|---|---|
| v06.01 | Initial release of v6 data. |
| v06.02 | Update to handling of Level 1 data inputs. |
| v06.03 | Updated in light of the deactivation of the high-altitude CO channels in 240-GHz radiometer. This was done in order to enable improved measurements of high-altitude magnetic field, a future research product. The only notable impact to v5 data is in CO, and then only for altitudes above ~60 km. |
| GMAO GEOS Version | Data used in MLS data processing |
|---|---|
| GEOS 5.29.4 | 2004 August 13 (d215) - present |
Version 5 Data Quality
Documents / Publications
- Version 5.0x Level 2 and Level 3 Data Quality and Description Document
- Aura MLS Radiance Average Retrievals (RAR) BrO Product Guideline
- Aura MLS Radiance Average Retrievals (RAR) HO2 Product Guideline
Data Processing Information Tables
| MLS Version | Major Change |
|---|---|
| v05.00 | Initial release of v5 data. |
| v05.01 | Minor bug fix related to flagging of bad GPH values. |
| v05.02 | Fixed minor bug in Level 1's calibration of the MLS instrument's digital auto-correlators (DACS). |
| v05.03 | Updates to cope with new GMAO GEOS inputs. |
| v05.04 | Updated in light of the deactivation of the high-altitude CO channels in 240-GHz radiometer. This was done in order to enable improved measurements of high-altitude magnetic field, a future research product. The only notable impact to v5 data is in CO, and then only for altitudes above ~60 km. |
