Research Overview


  • Dr. Velazco studied Physics and built a continuous wave CO2 laser system from the ground up 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 measurements from a high-powered laser LIDAR system 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 their effects on the atmosphere, using techniques in 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), which was partly funded for the validation of the SCIAMACHY satellite.

    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 embarked on measurement 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), proving and publishing the concept of detecting and monitoring power plant CO2 emissions from space with a CarbonSat-type satellite constellation.

    He works on retrievals and analysis of total carbon columns via ground-based solar spectrometry within TCCON (Total Carbon Column Observing Network), a global network dedicated to the precise measurements of greenhouse gases. He served as Deputy Chair for TCCON in the Asia-Pacific region until 2021 and managed the operations of two Australian TCCON stations: Wollongong and Darwin, including the processing, analysis, production and delivery of data products for validation of NASA's OCO-2 and Japan's GOSAT satellites.

    Together with NIES - Japan's focal point institute for environmental research and EDC - a company dedicated to providing 100% clean and renewable energy, he conceptualized and spearheaded the establishment of TCCON-Philippines, the first TCCON station in Southeast Asia. TCCON Philippines is powered by a mix of close to 100% renewable energy (Wind, Solar, Geothermal), courtesy of Energy Development Corporation, Philippines (EDC).
