Spring 2000 Science Plans, Greenland Environmental Observatory

January 10, 2000

Dear Colleagues,

Beginning this spring colleagues from both US and international institutions will commence studies at the Greenland Environmental Observatory (GEOsummit). The observatory is located at Summit, Greenland (72^oN, 38^oW), and is at the highest elevation north of the arctic circle. This unique location provides us the ability to make high quality measurements from a variety of scientific fields (see Whitepaper). The five priority areas that have been identified include i) ice-core interpretation, ii) tropospheric chemistry, iii) radiation, energy balance and boundary layer dynamics, iv) stratospheric observations, and v) atmospheric electricity. This season will primarily involve construction of towers, and installation of year-round monitoring equipment.

Currently the following institutions will be involved in the Summer 2000 field campaign:

• U. New Hampshire (Jack Dibb): accumulation stake array
• U. New Hampshire (Jack Dibb): high volume aerosol filters for natural radionuclides; major ions in surface snow
• U. Arizona (Roger Bales): hydrogen peroxide in atmosphere & surface snow
• Carnegie Mellon U. (Cliff Davidson): major ions on aerosol filters
• U. California Irvine (Don Blake): cannister samples for hydrocarbon, halocarbon and alkyl nitrate
• NIST (George Klouda): high volume aerosol filters for carbonaceous aerosols
• U. Pennsylvania (Eric Steig): stable isotopes in water vapor
• U. Wisconsin (Jon Kahl): back trajectory modeling
• USACE-CRREL (Mary Albert): snow & firn physical characteristics
• Desert Research Institute (Joe McConnell): development of high resolution trace element records
• NOAA CMDL (Sam Oltmans): atmospheric ozone
• NOAA CMDL (Tom Conway): cannister samples of air for carbon cycle (CO₂, CH₄, CO, H₂, N₂O, SF₆, & ¹³C & ¹⁸O in CO₂)
• ETH (Atsumu Ohmura): incoming and outgoing radiation
• National Survey and Cadastre, KMS, Denmark (Trine Dahl-Jensen & Soren Gregersen): seismic (pending NSF approval)

 Check frequently for updates.

Sincerely,

Roger Bales
