Brief Bio

David B. Wolff is Chief of the Earth Sciences Field Support Office, Code 610.W at NASA Wallops Flight Facility. Responsible for management and operation of Global Precipitation Measurement (GPM) Ground Validation (GV); Atmospheric Topographic Mapping (ATM)/Operation Ice Bridge; IceSat2; and Atmospheric Chemistry (Ozone Soundings) projects and science efforts (Precipitation Measurement Missions (PMM), Ocean Biology, Optics). Supervise the efforts of about 40 Civil Servant and contractor scientists, technicians and administrative specialists.


I also serve as the GPM Deputy Project Scientist for Ground Validation and the GPM Ground Validation System Manager, where I manage the GPM Ground Validation infrastructure including instruments, field campaign planning and execution and also manage GV budgets and grants and steer funded GV science efforts.


I have served 33 years as Tropical Rainfall Measuring Mission (TRMM) Ground Validation manager (SSAI) and/or GPM Science Team member at NASA GSFC and NASA Wallops Flight Facility and I am the author or co-author of 60 peer-reviewed journal publications. I served as Editor of the Journal of Applied Meteorology and Climatology from 2014-2016, a member of the Science Review Board for the HOPE/EPOCH program, and Chair of the Global Hydrology Resource Center Users Working Group. 


At NASA Wallops Flight Facility I am a voting member of the Wallops Management Advisory Committee (WMaC), and the Wallops Facilities Review Committee (WFRC).
