EPOCH Data Collection

The East Pacific Origins and Characteristics of Hurricanes (EPOCH) project was a NASA program manager training opportunity directed at training NASA young scientists in conceiving, planning, and executing a major airborne science field program. Combined with this goal, the EPOCH project was to sample tropical cyclogenesis, or intensification, of an Eastern Pacific hurricane. 

The EPOCH project consists of three payload instruments, ER-2 X-band Radar (EXRAD), High Altitude Monolithic Microwave Integrated Circuit Sounding Radiometer (HAMSR), and Advanced Vertical Atmospheric Profiling System (AVAPS), onboard the AV-6 Global Hawk Unmanned Aerial Vehicle research aircraft. The launch site was at the Armstrong Flight Research Center located on Edwards Air Force Base in California. The launch/flight window consisted of up to six 24-hour science flights from August 1, 2017, through August 31, 2017, over the Pacific Ocean.
