mask : set a given value as missing value ------------------------------------------ Set the given constant to missing value. **References** : https://code.zmaw.de/projects/cdo/embedded/index.html#x1-2440002.6.14 **Provider / contact** : climaf at meteo dot fr **Inputs** : any dataset (but only one) **Mandatory arguments**: - ``miss`` : the value you want to set as missing **Optional arguments**: - none **Output** : the masked dataset **Climaf call example**:: >>> # Plot a model MOC slice >>> moc_model=ds(variable="msftmyz", project='CMIP5',model='CNRM-CM5', frequency="mon", realm="ocean", >>> ... table="Omon", version="*", period="1980", experiment="historical",simulation="r1i1p1") >>> moc_model_mean=time_average(moc_model) >>> # Extract basin of rank 1 (def: Atlantic=1) >>> moc_model_mean_atl=slice(moc_model_mean, dim='x', min=1, max=1) >>> # Mask values >>> moc_model_mean_atl_mask=mask(moc_model_mean_atl,miss=0.0) >>> # Plot >>> plot_moc_slice=plot(moc_model_mean_atl_mask, title="MOC",y="index", >>> ... min=-10.,max=30.,delta=1.,scale=1e-3,units="Sv",options="trXMinF=-30.") >>> cshow(plot_moc_slice) **Side effects** : none **Implementation** : using CDO with operator setctomiss
