TL;DR: The first detailed field measurements of biomass burning (BB) emissions in the Northern Hemisphere tropics as part of the MILAGRO project were made by two instrumented aircraft were the National Center for Atmospheric Research C-130 and a University of Montana/US Forest Service Twin Otter.
Journal ArticleDOI
Dynamics and physiology of saxitoxin production by the dinoflagellates Alexandrium spp.
TL;DR: The results demonstrate that toxin production is a complex process which, under some conditions, is closely coupled to growth rate; under other conditions, these processes are completely uncoupled.
Journal ArticleDOI

Neuman,Xianliang Zhou,Xianliang Zhou +27 more
TL;DR: The authors used detailed chemical observations from the SEAC4RS aircraft campaign in August and September 2013, interpreted with the GEOS-Chem chemical transport model at 0.3125° horizontal resolution, to understand the factors controlling surface ozone in the Southeast US.
Journal ArticleDOI
Airborne measurement of OH reactivity during INTEX-B
Jingqiu Mao,Jingqiu Mao,Xinrong Ren,Xinrong Ren,William H. Brune,Jennifer R. Olson,James H. Crawford,Alan Fried,L. G. Huey,Ronald C. Cohen,Brian G. Heikes,Hanwant B. Singh,Donald R. Blake,G. W. Sachse,Glenn S. Diskin,Samuel R. Hall,Richard E. Shetter +16 more
TL;DR: In the second phase of the International Chemical Transport Experiment-B (INTEX-B) campaign as discussed by the authors, a new airborne OH reactivity instrument was designed and deployed for the first time on the NASA DC-8 aircraft, which was focused on the Asian pollution outflow over Pacific Ocean and was based in Hawaii and Alaska.
Journal ArticleDOI

TL;DR: In this paper, the authors present observations of NO, NO2, O3, OH, HO2, H2CO, actinic flux, and temperature obtained during the 1999 Southern Oxidant Study from June 15 to July 15, 1999, at Cornelia Fort Airpark, Nashville, Tennessee.
