aerioe > AERIoe Thermodynamic Profile and Cloud Retrieval for MC3E Garber X-band site (I5)Data Source Type(s) > PI • Guest

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).

Purpose

The data were created to characterize the evolution of the planetary boundary layer and boundary layer clouds.

Content time range 20 April 2011 - 4 June 2011
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
