The AERIoe algorithm retrieves profiles of temperature and water vapor mixing ratio, together with cloud properties for a single-layer cloud (i.e., LWP, effective radius), from AERI-observed infrared radiance spectrum. The method is a physical-iterative retrieval that uses the optimal estimation framework, so a full error covariance of the solution is provided for each retrieval. The information content in the AERI observations on the thermodynamic profiles is primarily concentrated in the lowest 3 km or up to cloud base; the retrieved data should not be used above that level (or used with caution).

Content time range | 18 September 2012 - 13 November 2012 |
Attribute accuracy | The retrieval uses an optimal estimation framework, so a full error covariance matrix of each solution is included in the output file. The 1-sigma uncertainty of each retrieved variable, which is derived from the error covariance matrix, is included for each scientific field and is named "sigma_X", where "X" is the name of the scientific field (e.g., 'temperature'). Note that there is also an overall "qc_flag" field that is set when a retrieval should not be trusted. |
Positional accuracy | No formal positional accuracy tests were conducted |
Data Consistency and Completeness | Data set is considered complete for the information presented, as described in the abstract.Users are advised to read the rest of the metadata record carefully for addtional details. |
Access Restriction | No access constraints are associated with this data. |
Use Restriction | No use constraints are associated with this data. |
File naming convention | Similar to ARM file naming convention |
Directory Organization | There will be subdirectories for different versions of the algorithm, with data and quick look subdirectories |
