EPOCH: East Pacific Origins and Characteristics of Hurricanes Dropsondes


This is the data archive site for the EPOCH-2017 Dropsondes. This NASA led project which planned six 24-hour science flights using the Global Hawk unmanned aircraft. Only three of the flights were conducted and those were supported through a partnership with the NOAA UAS Program. The aircraft flew over developing tropical cyclones and collected data using 3 on-board instruments (EXRAD, HAMSR, and AVAPS).
