Siri-Jodha Singh Khalsa received a B.A. in Physics from the University of California, Irvine, and his Ph.D. in Atmospheric Sciences from the University of Washington, Seattle. His early work in boundary layer turbulence and tropical air-sea interaction evolved into an interest in large scale inter-decadal trends in atmospheric structure revealed in satellite sounding records. Since 1993 he has supported NASA’s Distributed Active Archive Center (DAAC) at the National Snow and Ice Data Center (NSIDC) where he performs science evaluation and algorithm support for cryospheric data products derived from NASA’s Earth Observing System (EOS) satellites. He provided domain knowledge and experience to assist in the design and implementation of the EOS Data and Information System (EOSDIS), and ensured that the EOS Instrument Teams were kept informed of EOSDIS developments. He is also engaged in research on methods of remotely sensing glacier change as part of the Global Land Ice Measurements from Space (GLIMS) project.
Dr. Khalsa was nominated to the formulation team studying the evolution of NASA’s Earth Science Data Systems and is a charter member of NASA’s Standards Process Group. He is the IEEE Geoscience and Remote Sensing Society’s liaison to ISO/Technical Committee 211 (Geographic information/Geomatics) and is on the editorial board of the Springer journal Earth Science Informatics. He is on the board of the IEEE Committee on Earth Observations (ICEO) and has led the ICEO Standards Working Group (ISWG) since 1995. He is a member of the Architecture and Data Committee of the intergovernmental Group on Earth Observations (GEO) which is overseeing the creation of the Global Earth Observing System of Systems (GEOSS). He manages the GEOSS Interoperability Process Pilot Projects and is the lead of the GEO Standards and Interoperability Forum, endorsed by the GEO Secretariat to oversee interoperability issues for all of GEOSS.
