Goals: Control experiment for the O3+NO2+H2O2 series -- this one with no H2O2, and therefore likely very little HO2 formation during oxidation (more RO2 + RO2, some RO2 + NO3...

Surface and Upper air climatology. Upper air climatology interpolated from data supplied by NCAR from DS200.0and DS205.0, and data supplied by NOAA, USAF (ETAC), and others.

Goals: To produce toluene high NOx SOA for photochemical aging Summary: Toluene high NOx SOA was produced for photochemical aging through the reaction of toluene with the...

Goals: To derive an SOA mass yield curve for limonene + NO3 system. Summary: 0.4 uL of liquid limonene was injected, followed by the injection of 40 ppb of N2O5 (source of...

Goals: Part of a series to quantify the nitrooxy-hydroperoxide yield and the SOA yield from nighttime RO2+HO2-dominated NO3-initiated chemistry of a-pinene by adding H2O2 +...

Goals: Observing OH-initiated m-xylene reactions under SOA surrogate and NOx environment. Summary: Target: 1.1 ppmC SOA surrogate, 25 ppb NOx, 1 ppm H2O2, 25 ppb m-xylene (A)...

Goals: We oxidized D4 using HONO as the oxidant precursor to promote RO2 radical reactions with NO. Summary: The siloxanol was the main product formed. Organization: Browne Lab...

The Assessing Responses and Impacts of Solar climate intervention on the Earth system with stratospheric aerosol injection simulations (ARISE-SAI-1.5) utilize a moderate...

Goals: Fast burst photooxidation of alkanols (high-NOx). Gas-aerosol-wall partitioning kinetics. Determine accommodation coefficient (alpha) and effective volatility under...

The National Oceanographic Data Center (NODC) provided world-wide cruise data for input to the International Comprehensive Ocean-Atmosphere Dataset (ICOADS). The data include...

Goals: To characterize particulate organic nitrate generated from photooxidation of a-pinene in moderate NO level and to understand its hydrolysis process. Summary: SOA...

The 5-year (1985-1989) and long term monthly means are calculated using ECMWF global tropospheric analyses between December 1978 and December 1989. The results are archived in...
