The Deep Propagating Gravity Wave Experiment (DEEPWAVE) was a research project conducted over New Zealand to study how topography and tropospheric winds can induce the formation of gravity waves which propagate upward through the troposphere, into the stratosphere. The NSF/NCAR HIAPER Gulfstream-V research aircraft collected in-situ measurements using an automated Airborne Vertical Atmospheric Profiling System (AVAPS) dropsonde system. Two hundred eighty two dropsonde sounding data files, collected between June 6 and July 20, 2014, are contained in the quality controlled dropsonde data archive.

Additional information

Data Quality final
  • 1.0 (2015-02-04)
  • 1.2 (2016-06-09):

    This data has been corrected for a dry bias and the filenames have been changed.

  • 2.0 (2016-06-23):

    These files have been corrected for a temperature dependent dry bias and the filenames have been changed.  

  • 2.5 (2016-07-27):

    This version was corrected for a temperature dependent relative humidity dry bias as well as a dewpoint bias. This was formerly loaded as version 3.0, but has been renamed to version 2.5, as it is not the final version.

  • 3.0 (2016-09-09):

    These files have been corrected for a temperature dependent dry bias. This includes corrected RH and dew point temperatures. These files replace version 2.5, and represent the final version.

(Only the current version of the data is available to order. If you have questions about a prior version, please email us.)
