Data Quality	final
Versions	2.0 (2016-02-16): The second version of AMMA quality-controlled driftsonde data is different from the first version that was released on January 26, 2007 in the following ways: (1) The 1^st version of quality controlled (QC) data does not contain any calculated pressure values. Note that the Miniature In-situ Sounding Technology (MIST) dropsonde carried by the driftsonde did not have a pressure sensor. In the 2^nd version of the QCed data, pressure was calculated and stored in the final dataset (see details in Section 6 of Readme). (2) During this second phase of the data QC, the soundings (with calculated pressure included) were run through the Atmospheric Sounding Processing ENvironment (ASPEN) software, which analyzes the data, performs smoothing, and removes suspect data points. Additional QC procedures are also applied to the 2^nd version of the QCed data (see Section 6 of Readme). (3) The 2^nd version of QCed data is in the EOL sounding format (see Section 4 of Readme), while the 1^st version was in original D file format. The readme file for the 1^st version of QCed data has been included with the release of the 2^nd version of the data.
