HS3 2014 Global Hawk Dropsonde Data


The NASA Hurricane and Severe Storm Sentinel (HS3) 2014 was the third science field campaign of a multi-year investigation aimed at examining hurricane formation and intensity change. The 2014 phase of the campaign involved eleven research flights of the unmanned NOAA/NASA Global Hawk (GH) aircraft conducted between August 26 and September 30. The GH is equipped with an NCAR/NOAA dropsonde system specially designed for remote operation. A total of 656 quality controlled soundings are contained in the final HS3 dropsonde data set.
