Research Overview


  • Dr. Velazco studied Physics and worked in building up and characterizing a CO2 laser system for his Bachelor thesis. He moved to Bremen, Germany to undertake the Masters degree in Environmental Physics, where he studied aerosols and cirrus clouds using LIDAR measurements in the high Arctic (Ny Alesund, Spitsbergen). The work was in collaboration with the University of Bremen and the Alfred Wegener Institute for Polar and Marine Research.

    He later investigated the transport of pollutants from biomass burning and its effects on the atmosphere, with the help of Fourier Transform Infrared (FT-IR) Spectrometry on board the Research Vessel Polarstern, in the Arctic and in the tropics for his Doctorate (summa cum laude).

    As a CALTECH postdoctoral scholar, he worked at NASA's Jet Propulsion Lab, California Institute of Technology, investigating the upper atmosphere and validating satellite instruments using JPL's MkIV balloon-borne interferometer. He participated in campaigns in the Arctic (Esrange) to validate the measurements from MLS, HIRDLS and TES instruments on board the AURA spacecraft and in Fort Sumner New Mexico for the validation of ACE-FTS on the SCISAT spacecraft. In 2010, he worked on CarbonSat (a candidate for a future ESA Earth Explorer satellite), focusing mainly on detection of power plant CO2 emissions.

    He is currently working on retrievals and analysis of total carbon columns via ground-based solar spectrometry and satellites, as well as managing TCCON (Total Carbon Column Observing Network) stations in Wollongong, NSW, Darwin, NT and recently conceptualized and spearheaded the establishment of TCCON-Philippines, the first TCCON station in Southeast Asia.

Impact Story


  • <p>The project SATORI* successfully established the first satellite validation "super site" in Southeast Asia, through a unique 3-party collaboration among academia, research institute and industry.  The site is composed of state of the art instruments: a TCCON instrument, LIDAR and Sky radiometer, all dedicated to the validation of the GOSAT-2 satellite, the successor to GOSAT, the first satellite in space dedicated to greenhouse gas observations. GOSAT-2 was successfully launched on October 29, 2018, from the Tanegashima Space Center, Japan and is now gathering important data on the atmosphere with the new TCCON Philippines super site as its primary validation in the tropics.<br /><br />Southeast Asia is a region with high scientific importance for the understanding of the transport of trace gases into the stratosphere, but is also a region with very few ground-based measurements. <br /><br />TCCON (Total Carbon Column Observing Network) is a network dedicated to understanding the sources and sinks of greenhouse gases by making accurate and precise measurements of their total column amounts. With the global effort to cap greenhouse gas emissions, TCCON is a necessary benchmark to validate current and upcoming greenhouse gas monitoring satellites. But there had been no TCCON stations in Southeast Asia, until now.<br /><br />The threat of Climate Change is clear and present. Damages and casualties grow with extreme climate events, and scientists from all over the world converge to advance their research by expanding the coverage of the TCCON in order to understand the future of Earth’s climate and find ways to mitigate the effects of Climate Change. However, despite strong interests from the international scientific community, establishing a reliable ground-based validation station in the tropics has proved difficult, due to many factors such as logistics, local support and funding.</p><p>Through this unique collaborative effort spearheaded by Dr. Voltaire A. Velazco, a three-party team composed of the University of Wollongong, the Energy Development Corp. (EDC), a world leader in geothermal energy production and Japan’s National Institute for Environmental Studies (NIES), Japan’s forefront in environmental research, was forged with the objective of establishing the first TCCON station in Southeast Asia. After 4 years of challenging, collaborative work, this objective was finally accomplished. Since its establishment, TCCON Philippines has led to 2 first-author papers, 1 NASA OCO-2 paper, 3 annual reports, 5+ conference presentations, ESA Sentinel 5P validation presentations and has been an important participant in two international high value missions: EU's EMeRGe (EUR 6M) and NASA's CAMP2Ex (US$ 13.7M).<br /><a href="TCCON%20Philippines" title="TCCON Philippines website" target="_blank" rel="noopener"></a>TCCON Philippines showcases a project where a university, industry and a research institute can work together and benefit, while creating a positive impact globally.
