May 03 1996: History of ozn.T42.0596, the CCM3 Ozone boundary dataset Cray COS blocked files: MSS Name: /CCM3/data/ozn.T42.0596 Disk name: /ccm/CCM3/data/ozn.T42.0596 Aliases: /ccm/CCM3/T42/ozn /ccm/ccm2/T42/ozn /CCM2/T42/%data%/ozn Variables: OZONE (fraction) PS (m**2/s**2) Coverage: Global (zonally averaged) Dates: 12 time samples Format: CCM2 History tape format (see NCAR TN-379+IA 'Users's Guide to NCAR CCM2'). History: This dataset is the same T42 ozone boundary dataset used in CCM2. This dataset contains ozone volume mixing ratios for an arbitrary number of vertical levels. These levels are defined by the sigma arrays contained in the real portion of the dataset header. CCM3 reads these values and then interpolates to the Model vertical levels at each longitude point on the grid. The ozone dataset is in the form of a history file containing the fields PS and OZONE. PS is a constant 1000 millibar (100,000 Pascal) pressure field and is provided so the user can request a pressure interpolation to produce pressure plots using the CCM Processor. Because the ozone data do not vary in longitude, each of the 12 monthly time samples contains plat records of a given number of levels by one longitude.
