GLOBALVIEW-CO2, 2011

  1. Release Date: 16 September 2011
  2. Data additions
    Discrete surface measurements:
    • CIB Centro de Investigacion de la Baja Atmosfera, Spain (ESRL in collaboration with Centro de Investigacion de la Baja Atmosfera, Univ. of Valladolid (CIBA))
    • DRP Drake Passage (ESRL in collaboration with the National Science Foundation (NSF))
    • MEX Mex High Altitude Global Climate Observation Center, Mexico (ESRL in collaboration with Sistema Internacional de Monitoreo Ambiental (SIMA))
    • OXK Ochsenkopf, Germany (ESRL in collaboration with Max Planck Institute for Biogeochemistry (MPI-BGC))
    Continuous surface or short-tower measurements:
    • ESP045 Estevan Point, British Columbia, Canada (EC)
  3. Site Classification Change
    Discrete data from Estevan Point are no longer included in constructing the marine boundary layer (MBL) reference matrix. Quasi-continuous measurements from the site show a small diurnal cycle. Discrete samples are not always collected at a time when air is predominantly marine in origin.

    All EC quasi-continuous measurement records are now designated as continuous surface sites (_06C0) instead of continuous tower sites (_06C3). The "tower" designation is reserved for records where GLOBALVIEW results from multiple levels on the tower are presented (e.g., hun, lef, wkt).
