NAM_DIAG - Clustering

Fortran name

Fortran type

Default value

LCLSTR

LOGICAL

.FALSE.

LBOTUP

LOGICAL

.TRUE.

CFIELD

CHARACTER(LEN=8)

‘CLOUD’

XTHRES

REAL

0.00001

  • LCLSTR : flag for 3D clustering

  • LBOTUP : to propagate clustering from bottom to top (when TRUE); otherwise from top to bottom

  • CFIELD : field on which clustering is applied, could be ‘W’ or ‘CLOUD’

  • XTHRES : threshold value to detect the 3D structures

Following variables will be stored :

Name

Meaning [Unit]

Dimension

CLUSTERID

identity number

3D

CLUSTERLV

level where the object has been identified for the first time (at its bottom if LBOTUP is true, at its top otherwise)

3D

CLDSIZE

horizontal section of the object at the current level

3D

Note

Together, CLUSTERID and CLUSTERLV refers univoqually to a unique 3D object. Their value is homogeneous inside each identified object. CLOUDSIZE is homogeneous at each level inside each object.
