Goals: Study methacrolein low NO chemistry. Summary: We successfully oxidized MACR in low NO conditions. About 9 ppb was remaining by the time we turned off lights. After we...

Goals: PM Wall loss without blacklights: Pressure Machine Wall loss is the walls of the level weaken and eventually break down when the pressure is high enough. Blacklights are...

In this dataset, elemental/trace metal composition of PM2.5 aerosol is measured by x-ray fluorescence (Xact-625i, Sailbri Cooper Inc.). Data are reported at 1-hour (at urban...

Goals: To quantify the nitrooxy-hydroperoxide yield and the SOA yield from nighttime RO2+HO2-dominated NO3-initiated chemistry of a-pinene by adding H2O2 + ozone + NO2 to the...

Goals: To calculate SOA yield from Cl-initiated photooxidation of isoprene at a VOC:Cl2 ratio of 0.42, and using neutral seed. Cl was continuously injected throughout the...

Goals: Prepare NAP SOA at 0 RH, with high NOx, and with NH3 Summary: Prepare NAP SOA at 0 RH, with high NOx, and with NH3 Organization: Nizkorodov Lab Lab Affiliation:...

Goals: Observing OH-initiated m-xylene reactions under SOA surrogate and NOx environment. Summary: targets: 2.2 ppmC SOA surrogate + 1 ppmC H2O2 + 25 ppb NOx + 100 ppb m-xylene...

This dataset contains 100 days of tropical wind analyses for the 300mb, 250mb, and 200mb levels. These analyses were provided by T.N. Krishnamurti at Florida State University....

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...

This dataset contains data from radiosonde observations made during the National Hail Research Experiment. Upper air data are available for the summers of 1972, 1973, 1974,...

The isentropic level analysis data from ECMWF ERA-40 reanalysis project are available in this dataset.

Goals: Determine atmospheric photooxidation pathways for ethyl acetate, specifically examine chemistry of CH3CH2C(O)OCH(O.)CH3 radical vs. T and O2 partial pressure Summary:...

Goals: Find SOA yield for decane + Cl under high NOx condition (NO injected). Investigate volatility behavior based on 2D thermograms. Summary: Ammonium sulfate seed (0.01M, 150...

The SO2 injection matrix simulations were performed to perform a system identification of the Whole Atmosphere Community Climate Model (WACCM), to identify the aerosol optical...

The current operational PERSIANN (Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks) system uses neural network function...

Ensemble Earth system model predictions initialized from states close to observations generally drift away from observed climatology and towards a biased model climatology over...

A collection of various sample data for the VAPOR (Visualization and Analysis Platform for Ocean, Atmosphere, and Solar Researchers) software.
