  fcfield,
  obfield,

)

Arguments

fcfield

The forecast field

obfield

The observation field

thresh_scale

Used for threshold of object boundaries: Rmax/threshscale

min_rain

The minimum value to be considered. If no grid point is above, SAL is not computed.

same_threshold

If TRUE, threshold is a single number for both fields

maxobj

Maximum number of objects to identify

add_objs

If TRUE, the object matrices are returned as attributes of the result.

...

Ignored options.

threshold

A 2-vector containing (precipitation) thresholds for fc and obs.

Value

a data.frame with S, A, L values.
