Long-Term Ground-Based HR-FTIR Measurements of Several Tropospheric and Stratospheric Gases

High spectral resolution infrared Fourier-transform spectrometers are used to retrieve long-term key atmospheric compounds and evaluate their spatial and temporal variability at Mauna Loa, Hawaii, and at Thule, Greenland as part of the Infrared Working Group (IRWG) of the Network for the Detection of Atmospheric Composition Change (NDACC) and in Boulder, CO.

The geographic bounding box information associated with this dataset are: Mauna Loa: 19.54N, 155.57W; Thule: 76.53N, 68.74W; Boulder: 40.04N, 105.24W

The temporal information related to this dataset are: Mauna Loa: 1995-08-25 12:00:00-present; Thule: 1999-10-10 12:00:00 - present; Boulder: 2010-01-08 12:00:00-present

Legal Constraints

All data more than two years old are public data. Additionally, some principal investigators have authorized their data for early release. All data newer than one year from acquisition and not authorized for early release are proprietary data and available only through direct accounts on the Network for the Dtection of Atmospheric Composition Change (NDACC) database.
Access Constraints Parties interested in general access to data categorized as "proprietary" should prepare a proposal to the NDACC Steering Committee for consideration as NDACC collaborators. Additional information under the "Publication Considerations" section under the resource homepage should also be reviewed and considered.
