HS3 2012 Global Hawk Dropsonde Data


This data set contains Global Hawk dropsonde data from six research flights of the unmanned NOAA/NASA Global Hawk (GH) aircraft conducted between September 7 and 26, 2012 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 337 quality controlled soundings are contained in the final HS3 dropsonde data set. Version 5 of the dataset was corrected for a dry bias of the RH sensor and dewpoint was recomputed, however in creating these we lost the GPS filtering correction that had been applied to version 3. Version 6 contains both the dry corrections and the GPS filtering of latitude, longitude and altitude.

    This new release includes a new correction for a temperature dependent RH dry bias.

  • 2.0 (2013-04-22):

    Had a .4mb pressure correction applied and near surface data, that had been accidentally truncated, was restored

  • 3.0 (2015-05-27):

    Filtered out spikes in GPS positions cause by telemetry noise

  • 5.0 (2016-07-29):

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

  • 6.0 (2018-07-13):

    Filtering of GPS lat, lon and alt applied
