Version number or experiment identifier.
(4 ASCII characters, right justified) |
| 50 |
perturbationNumber |
unsigned |
Set to 0 for MARS labeling (simple labeling).
When element 40 = 1035, this is the ensemble forecast number.
When element 39 = 10, this is the control forecast number and is set to 0.
When element 39 = 11, this is the perturbed forecast number in some range 1-nn.
Positive perturbations have odd numbers and negative have even numbers. They
go in pairs (1,2), (3,4) etc.
When element 39 = 17, this is an ensemble mean and the number is set to 0.
When element 39 = 18, this is an ensemble standard deviation and the number
is set to 0.

in an ensemble; the number includes the control forecast. |
