Dr. Zhong Liu is a research professor at the Center for Spatial Information Science and Systems (CSISS), College of Science. He is a member of the NASA GES DISC Data Support Team to provide support for TRMM and other global precipitation data sets. Over the years, Dr. Liu has developed technologies for fast and easy access of NASA high volume data products. He was the lead developer for the NOAA/NESDIS Interactive Multi-sensor Snow and Ice Mapping System (IMS) project. He initiated the TRMM Online Visualization and Analysis System (TOVAS), the very first instance of the NASA Goddard Giovanni family, and has been the lead developer since then. He has been the lead developer of the Hurricane Data Analysis Tool (HDAT) in the GES DISC Hurricane Portal. He is the principal investigator for "Integrate IPWG Validation Algorithms into TRMM Online Visualization and Analysis System (TOVAS)" and was a co-investigator of "Integrating NASA Earth Science Enterprise Data into Global Agricultural Decision Support Systems" and the lead developer of the global agriculture information system. His specialties are 1) remote sensing applications; 2) interdisciplinary research; and 3) TRMM/GPM data support.


The Center for Spatial Information Science and Systems (CSISS) is an interdisciplinary research center chartered by the provost and affiliated with the College of Science at George Mason University, Fairfax VA, 22030, U.S.A.

CSISS currently operates Laboratory for Advanced Information Technology and Standards (LAITS)

CSISS is a member of National Committee on Information Technology Standards Technical Committee L1, and a member of Open GIS Consortium (OGC).
