During his tenure with Ocean University of Qingdao (1982-1993), he
served as lecturer, and associate professor, and held leadership roles
in multiple international corporation projects. From 1987 to 1993, he
was a visiting scientist at University of Dundee (UK), Division of
Atmospheric Research, Australian Commonwealth Scientific and Research
Organization (CSIRO), and Colorado Center for Astrodynamics Research,
University of Colorado (CU). In 1996 he joined the Earth Observation
System Satellites program through Raytheon ITSS and George Mason
University, and worked at NASA Goddard Space Flight Center (GSFC).
Currently Dr. Yu serves as a physical scientist at NOAA/NESDIS Center
for Satellite Applications and Research, chairman of the Land Surface
Algorithm Working Group of GOES-R satellite mission, and member of the
NPOESS VIIRS Operational Algorithm Team.
Dr. Yu has accomplished a variety of projects in ocean and land
surface remote sensing and applications. From 1987 to 1994, he focused
on satellite sea surface temperature (SST) retrieval and applications,
and developed two SST algorithms. He applied the SST data, as well as
altimeter data, in his Pacific Warm Pool Variation study and Global
SST Pattern analysis. From 1996 to 2000 he was involved in developing
earth observation systems for ocean products. He developed several
methods for computing and demonstrating ocean remote sensing products
using advanced IT techniques. In particular, a video tape was produced
and distributed at NASA which demonstrates global ocean current
patterns using particle-track technique; several art works of global
SST and ocean current patterns were used by the National Geographic
Program.
In 2002, Dr. Yu 'landed' and focused on satellite land surface
remote sensing research and applications, through the National Polar-
orbiting Operational Environmental Satellite System (NPOESS) program.
He was in charge of algorithm development for land surface albedo
product from the Visible and Infrared Imaging Radiometer Suite
(VIIRS), and was the leading author of the VIIRS albedo Algorithm
Theoretical Bases Document (2004). From 2006 he has been in charge of
the algorithm development for land surface temperature product from
the GOES-R Advanced Baseline Imager (ABI). He has served as Land Team
chair of the GOES-R Algorithm Working Group (AWG) since 2007, for
developing all the GOES-R land surface products including LST,
Normalized Difference Vegetation Index (NDVI), Active Fire/Hot Spot
Characterization, Albedo, Flood/Standing Water, and Green Vegetation
Fraction. Also, he is the VIIRS land product calibration and
validation team member, leading validation activities for land surface
temperature product.
