Summary
Quality-controlled driftsonde sounding data for the African Monsoon
Multidisciplinary Analysis (AMMA) project. A total of 124 soundings are
contained in the quality final archive.

Versions
  2.0: 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 1st 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 2nd 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
2nd version of the QCed data (see Section 6 of Readme). (3) The 2nd
version of QCed data is in the EOL sounding format (see Section 4 of
Readme), while the 1st version was in original D file format. The readme
file for the 1st version of QCed data has been included with the release
of the 2nd version of the data.
