Goals: Observing NO-initiated isoprene reactions under SOA surrogate and NOx environment. Summary: Target: 1.1ppmC SOA surrogate, 25ppb NOx, 100 ppb isoprene (A) INSTRUMENTS:...

To gain insight into the atmospheric teleconnections associated with the AMV, we perform idealized experiments using Community Earth System Model version 1 (CESM1) in which...

Goals: Determine the chemistry resulting in hydroxybenzoquinone increasing in concentration after photooxidation ends. Summary: 300 ppb of resorcinol was added as 2 ppm of...

Goals: This experiment was done to react 2-Methyl-3-buten-1-ol (231 MBO) with ozone to produce the Hydroxymethylpropanal (HMPR). After oxidizing HMPR with OH in the high NO2...

The National Centers for Environmental Prediction (NCEP) Climate Forecast System (CFS) is initialized four times per day (0000, 0600, 1200, and 1800 UTC). NCEP upgraded CFS to...

The 15-minute precipitation observations contained in this set were obtained from the National Climatic Data Center (NCDC). The sites are located in the contiguous U.S., Alaska,...

A 10-member ensemble of CESM2 (1 degree spatial resolution) simulations in which time-evolving SST anomalies in the eastern tropical Pacific are nudged to observations (NOAA...

The NOAA Profiler Network (NPN) has 35 unmanned Doppler Radar sites in 18 central US states and Alaska. They provide hourly vertical profiles of wind data. The hourly netCDF...

Goals: Investigate atmospheric fate of ethyl formate, specifically looking at the chemistry of the HC(O)OCH(O.)CH3 radical as a function of T and O2 partial pressure. Summary:...

The Stratospheric Aerosol Geoengineering Large Ensemble project (GLENS) is a 20-member ensemble of stratospheric sulfate aerosol geoengineering simulations between 2020-2099 and...

Goals: Investigate vapor-wall loss rates of isoprene, MACR, and MVK at RH = 85% Summary: Obtained temporal profiles of three compounds with GC-FID Organization: Caltech...

This dataset contains the original and modified versions of MPAS v7.3 code used for the simulations described in a manuscript submitted for publication in the Journal of...

Goals: Observing OH-initiated m-xylene reactions under SOA surrogate and NOx environment. Summary: targets: 1.1 ppmC SOA surrogate + 1 ppmC H2O2 + 25 ppb NOx + 250 ppb m-xylene...

Note: d559000 Four-kilometer long-term regional hydroclimate reanalysis over the conterminous United States (CONUS) has superseded this dataset. <p>The dataset is from a...

Goals: Control (no NO2) for 20190725, which itself is a control experiment for the O3+NO2+H2O2 series -- this one with no H2O2, and therefore likely very little HO2 formation...

Goals: Determine SOA yield of OH radical oxidation of the VOC Summary: Alkanes were reacted with OH radicals in the presence of NOx in a 5900 L PTFE environmental chamber filled...

Marine surface data (ship observation, moored buoys, etc) are segregated from the GTS data stream at NCDC. The GTS records are encoded into IMMA format and collected into...

The National Meteorological Center (NMC) produced weekly Northern Hemisphere atmospheric analyses from available radiosonde and rocketsonde data at various vertical levels, and...

This dataset contains constant-level balloon observations from the First Global GARP Experiment (FGGE) for 7 January to 16 July 1979.

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