First local C-130 flight from Veracruz
This picture shows us getting ready for the first local flight of the NCAR/NSF C-130 flying out of Veracruz. We flew toward Mexico City, did some measurements in the Mexico City basin, and then flew West and South of the city before returning to Veracruz. The flight lasted about 7 1/2 hours. Most of the instruments are the aircraft were operational, so we should have a good data set for conditions when the wind is blowing from the Northeast.
Our instrument makes measurements of OH (hydroxyl radicals), H2SO4 (sulfuric acid), MSA (methane sulfonic acid), HO2 (hydroperoxy radicals), RO2 (organic peroxy radicals), HNO3 (nitric acid), and NH3 (ammonia). It uses the technique of selected ion chemical ionization mass spectroscopy.
More later,
