This dataset contains Global Hawk dropsonde data from two research flights of the unmanned NOAA/NASA Global Hawk (GH) aircraft conducted on September 9 and 14, 2011 for the Hurricane and Severe Storm Sentinel (HS3) project. The GH is equipped with an NCAR/NOAA dropsonde system specially designed for remote operation. A total of 79 quality controlled soundings are contained in the final HS3 dropsonde data set.

Additional information

Data Quality final
  • 1.0 (2011-11-10)
  • 2.0 (2016-05-31):

    This dataset includes a new correction for a temperature dependent RH dry bias and has corrected for an error in the previously updated version.

  • 1.2 (2016-06-09):

    This dataset includes accidentally duplicated files that had been corrected for a dry bias. This version was never released and has thus been named version 1.2.

  • 1.1 (2016-06-22):

    This dataset includes a correction for a temperature dependent RH dry bias. This dataset included an error that has been removed from version 2.0. Since this was not released, it's version was changed to 1.1.

  • 3.0 (2016-07-29):

    This dataset includes a correction for a temperature dependent RH dry bias and a dew point temperature correction.
