Science Summary:
This grant will allow the PI continuous measurements of atmospheric methane, and non-methane hydrocarbons (NMHC: ethane, ethyne, propane, iso-butane, n-butane, iso-pentane, n-pentane, benzene, toluene) at the Greenland Environmental Observatory at Summit (GEOSummit) over the summer of 2018. The project utilizes an existing monitoring system that has previously been operated at Summit. This gas chromatography instrument is specifically tailored towards operation at this remote arctic site as it is fully automated and controlled remotely. A second analytical channel will be added to include monitoring of the important climate gas methane. These measurements will complement the NMHC monitoring within the NOAA-INSTAAR global flask sampling program, which has provided bi-weekly NMHC data for five arctic sites. The much higher resolution in-situ data from this study will add value to the interpretation of the NMHC flask records. By applying chemical transport modeling, the in-situ data will allow researchers to decipher air pollution transport into the Arctic and contributions from different emission source regions at lower latitudes. The methane and NMHC monitoring will make a pivotal addition to the World Meteorological Organization (WMO) Global Atmospheric Watch (GAW) Volatile Organic Compound (VOC) program, as it will provide the only high time resolution in-situ NMHC site in the Arctic.

Logistics Summary:
This grant will allow the PI to continue measurements of atmospheric methane, and non-methane hydrocarbons (NMHC: ethane, ethyne, propane, iso-butane, n-butane, iso-pentane, n-pentane, benzene, toluene) at the Greenland Environmental Observatory at Summit (GEOSummit) through October 2018. The project utilizes an existing monitoring system that has previously been operated at Summit under NSF grant 1108391. This gas chromatography instrument is specifically tailored towards operation at this remote arctic site as it is fully automated and remotely controllable. A second analytical channel will be added to include monitoring of the important climate gas methane with the same instrument. In 2018, the research group will send one participant to perform regular maintenance on the gas chromatograph instrument. The agreement with NASA allowed the measurements to continue uninterrupted through the end of September 2018. Beginning in October 2018 the support for the project will be provided by NSF 1822406 and will extend until the summer of 2023.

CPS will provide ANG coordination for passengers and cargo, compressed hydrogen and cylinder rental, lodging at the KISS facility in Kangerlussuaq, user days and access to the Summit Station infrastructure, rack space in TAWO and power to instrument, and as-needed science technician support. NSF will recoup this support through an interagency funds transfer with NASA. All other costs associated with this project will be paid by the PI.
