ILAMB.Variable.Variable.spatialDistribution

Variable.spatialDistribution(var, region='global')[source]

Evaluates how well the input variable is spatially distributed relative to this variable.

This routine returns the normalized standard deviation and correlation (needed for a Taylor plot) as well as a score given as

\[\frac{4(1+R)}{((\sigma+\frac{1}{\sigma})^2 (1+R_0))}\]

where \(R\) is the correlation, \(R_0=1\) is the reference correlation, and \(\sigma\) is the normalized standard deviation.

Parameters

  • var (ILAMB.Variable.Variable) – the comparison variable

  • region (str, optional) – the name of the region over which to check the spatial distribution

Returns

  • std (ILAMB.Variable.Variable) – the normalized standard deviation of the input variable

  • R (ILAMB.Variable.Variable) – the correlation of the input variable

  • score (ILAMB.Variable.Variable) – the spatial distribution score
