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 currently works on retrievals and analysis of total carbon columns via ground-based solar spectrometry and satellites. From 2012 to 2017, he managed the operations of two Australian TCCON (Total Carbon Column Observing Network) 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. He conceptualized and spearheaded the establishment of TCCON-Philippines, the first TCCON station in Southeast Asia.

Impact Story


  • <p>This project established the first greenhouse gas (GHG) observing satellite validation "super site" in Southeast Asia in 2017, through a unique 3-party collaboration among academia (UOW), research institute (NIES) and industry (EDC).  The site is composed of state of the art instruments, all dedicated to the validation of the GOSAT-2 satellite, the successor to GOSAT, the first satellite in space dedicated to greenhouse gas observations. In 2018 the TCCON Philippines site took part in a European project to study the effects of megacity emissions (<a href="http://www.iup.uni-bremen.de/emerge/home/home.html" target="_blank" rel="noopener">EMeRGe</a>), making UOW the only Australian partner in this high-value mission. In 2019, the TCCON Philippines team was one of the selected science teams as part of a huge NASA mission: <a href="https://espo.nasa.gov/camp2ex/content/CAMP2Ex" target="_blank" rel="noopener">CAMP2Ex</a>. And in 2020, the TCCON Philippines science team became co-recipients of the prestigious NASA Group Achievement Award for an outstanding group accomplishment that has contributed substantially to NASA's mission.
