-start_ft, -start_FT, -end_ft, -end_FT¶

Introduction¶

Suppose you make a forecast starting from initial conditions of 00Z January 1 for the average conditions from the month of February. In this forecast, there are three time stamps.

   Name                        date           YYYYMMDDHH option  (HH)Z(DD)(MON)YYYY option      with minutes and seconds

   reference time              00Z Jan 1     -t                  -v2 -t                         -T
   start of forecast period    00Z Feb 1     -start_ft           -v2 -start_ft                  -start_FT
   end of forecast period      00Z Mar 1     -end_ft             -v2 -end_ft                    -end_FT

For common ftimes,

analysis:                      reference time == start_ft == end_ft
6 hour forecast:               reference time + 6 == start_ft == end_ft
30 year monthly climatology:   reference time = start_ft = start of 1st month used to make climatology
                               end_ft = end of the last month used to make the climatology
## Usage

-start_ft -end_ft -start_FT -end_FT

### Example

$ wgrib2 a.grb -start_ft 1:0:start_FT=20111101000000
