Proposed CVM-H Model

Characteristics of the NetCDF version of CVM-H is:

• Coverage Region is CVM-H Low Resolution region
  • dataset.geospatial_lat_min = 30.95
  • dataset.geospatial_lat_max = 36.613
  • dataset.geospatial_lon_min = -120.862
  • dataset.geospatial_lon_max = -113.333
  • dataset.geospatial_vertical_min = -50.0
  • dataset.geospatial_vertical_max = 4.0
  • dataset.geospatial_vertical_units = "km"
  • dataset.geospatial_vertical_resolution = z_size
  • dataset.geospatial_vertical_positive = "up"

• Resolution is 1km x 1km x .5km (depth)
  • n_lon_steps = 754
  • n_lat_steps = 566
  • n_z_steps = 109
  • total_pts = 46,517,276

• CVM-H flags used in model extraction:
  • cvmh_param=USE_1D_BKG,True
  • cvmh_param=USE_GTL,False
