CVM-H Model in IRIS EMC
With the model in EMC, IRIS webtools can be used to query it. Basically, you build a query, and use the model name in the query, and the EMC can query the contributed version of CVM-H.Examples below:
The EMC Query service documentation:
http://service.iris.edu/irisws/earth-model/1/
To get metadata about this CVM-H model:
http://service.iris.edu/irisws/earth-model/1/modelinfo?model=CVM*&nodata=404
To query data for a single point: (This generates and downloads a geocvs file)
http://service.iris.edu/irisws/earth-model/1/line?model=CVM_H_v15_1&variable=vs,vp,rho&latitude=32.5780&longitude=-120.8620&mindepth=-18.0&maxdepth=-17.0&format=geocsv&nodata=404
To slice the model: (This generates and downloads a geocsv file)
http://service.iris.edu/irisws/earth-model/1/plane?model=CVM_H_v15_1&variable=vs&minlatitude=31.0&maxlatitude=33.0&minlongitude=-120.0&maxlongitude=-119.0&depth=-40&format=geocsv&nodata=404
Proposed CVM-H Model
Characteristics of the NetCDF version of CVM-H are:
- 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
- Coverage Region is CVM-H Low Resolution region
- dataset.geospatial_lat_min = 30.95
- dataset.geospatial_lat_max = 36.613
- dataset.geospatial_lat_units = "degrees_north"
- dataset.geospatial_lat_resolution = 0.01
- dataset.geospatial_lon_min = -120.862
- dataset.geospatial_lon_max = -113.333
- dataset.geospatial_lon_units = "degrees_east"
- dataset.geospatial_lon_resolution = 0.01
- dataset.geospatial_vertical_min = -50.0
- dataset.geospatial_vertical_max = 4.0
- dataset.geospatial_vertical_units = "km"
- dataset.geospatial_vertical_resolution = 0.5
- dataset.geospatial_vertical_positive = "up"
- Variable Names, Units, and Ranges
- vp.long_name = "P Velocity"
- vp.display_name = "P Velocity (km/s)"
- vp.units = 'km.s-1'
- vp.valid_range = 0.0,10.0
- vp.missing_value = -99999.00
- vs.long_name = "S Velocity"
- vs.display_name = "S Velocity (km/s)"
- vs.units = 'km.s-1'
- vs.valid_range = 0.0,10.0
- vs.missing_value = -99999.00
- rho.long_name = "Density"
- rho.display_name = "Density (kg/m^3)"
- rho.units = 'kg.m-3'
- rho.valid_range = 0.0,8000.0
- rho.missing_value = -99999.00
- CVM-H flags used in model extraction:
- cvmh_param=USE_1D_BKG,True
- cvmh_param=USE_GTL,False
