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 Ivan Ortega, NCAR, Co-PI onGoing James Hannigan UCAR/NCAR jamesw@ucar.edu pointOfContact Ivan Ortega UCAR/NCAR iortega@ucar.edu pointOfContact HDF Dataset theme Resource Type 2017-10-30 publication DataCite originator 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. 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. eng Multiple times every day 1995 HDF NOAA Network for the Dtection of Atmospheric Composition Change (NDACC) distributor
