Data Resources

Data collected through the GEOSummit baseline measurement program is available to interested parties. Currently data requests are being managed through the SCO. For the most up to date information contact the SCO. Archived data is available through our digital library, and the other various links found below.

Data & Analysis Tools

Long Term Observations

IASOA  A first resource for pan-Arctic measurements, we are working to provide a complete listing of measurements to the data portal maintained by The International Arctic System for Observing the Atmosphere.

NOAA-ESRL – Direct access to the Global Monotoring Division FTP sites providing data for the following variables: Surface Ozone, Meteorology, CFC-11, CFC-113, CFC-12, Carbon Tetrachloride, Halon-1211, Methyl Chloroform, Nitrous Oxide, Sulfur Hexafluoride, C13/C12 in Carbon Dioxide, Carbon Dioxide, Methane, O18/O16 in Carbon Dioxide, Ozone, ethane, i-butane, i-pentane, n-butane, n-pentane, propane

ACADIS  – Core Atmospheric Measurements at Summit Greenland Environmental Observatory at the Advanced Cooperative Arctic Data and Information Service (ACADIS). This is the official repository for the Long Term Observations (LTO) at Summit, but much of the more recent data is available through direct request from the PI (Joe McConnell). Measurements include: Weekly and monthly snow height changes, ICP-MS measurements of surface snow trace elements, UC Davis DRUM aerosol sampler, radionuclide filters, atmospheric soundings (see also ICECAPS), and monthly snow pit samples.

FLEXPART – FLEXPART Lagrangian Transport calculations by the Norwegian Institute for Air Research (NILU). These are helpful for understanding the observed air mass histories at the station. If runs for your period of interest are not available, please contact the PI (John Burkhart).

ICECAPS Data – Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit (ICECAPS). Numerous upward looking remotely sensed data from ground-based lidar and radar including: millimeter cloud radar, CAPABL backscatter lidar, ceilometer, Doppler, Sodar, Total Sky Imaging, and Radiosonde data.

GC-NET – Greenland Climate Monitoring Network, CU, Boulder. An extensive resource for meteorlogical data related to Greenland can also be found here. Additionally, you may wish to contact individuals involved with the PARCA project.

NSF Polar Programs UV Monitoring Network – The National Science Foundation (NSF) Ultraviolet (UV) Monitoring Network was established in 1987 by the NSF Division of Polar Programs. Observations include the Arctic and are now part of NSF’s Arctic Observing Network. The project is providing data to researchers studying the effects of ozone depletion on terrestrial and marine biological systems. Data are also used for the validation of satellite observations and for the verification of models describing the transfer of radiation through the atmosphere.


Geographic Information Services

A kinematic survey GPS basestation and roaming receiver is available on station for use. For more information, follow the links below.

Instrument and Sampling Protocols

GEOSummit Protocols (caution, slow download) – For every instrument or sample collection program left at the station, it is required to provide a Protocol Document for the year-round science technicians.

Investigator Specific Data

Currently there is not a central platform for multi-collaborator data distribution. For specific information related to research it is recommended to contact investigators directly. For questions regarding the best point of contact, please feel free to query:
