Department of Environment and Natural Resource Secretary Maria Antonia Yulo Loyzaga (2nd from left) explores the National Aeronautics and Space Administration’s (NASA) DC-8 equipment payload on February 8 at the Asian Aerospace in Clark, Pampanga. These air quality monitoring systems and equipment measure the various atmospheric parameters such as the Aerosol Optical Depth (AOD), Tephigram soundings, gasses such as NO2, O3, CO, CH4, HCs, black carbon, particulate speciation, cloud condensation nuclei, acids, and chlorides. The data gathered by the air quality monitoring system and equipment will be used for the analysis and publication of findings in producing a Science Synthesis Report for the Philippines. The exploration was guided by NASA’s Tropospheric Composition Program Manager Dr. Barry L. Lefer (leftmost) and joined by the Ambassadors of the Republic of Korea and Thailand to the Philippines (L-R) H.E. Tull Traisorat and H.E. Lee Sang-hwa, and Malacanang Press Briefer Daphne Osena-Paez.
