Program add_noonpos

Configuration file

The options for the execution of add_noonpos can be set in the configuration file add_noonpos.inp:

1)  mls_050115.nc                 ! input file
2)  mls_050115_noonpos_new.nc     ! output file
3)  1           ! Anz. zusammenzufassender Tage (1->NOONPOS, >1->SYNPOS)
4)  n           ! benutze ZETA fuer traj (y->ZETA,n->THETA)
Possible dimensions of latitude are `(time)`, `(level,time)` or `(time,level)`
5)  press       ! Shortname fuer Level (NONE fuer Zeitreihen)
6)  LAT         ! Shortname fuer Breitengrad

14) /home/icg1/icg112/clams/traj/traj             ! ausfuehrbares Trajektorienprogramm
15) THETA_DOT  ! short name of variable containing THETA-DOT information
16) 6          ! Data frequency in hours (1,2,3,4,6,8,12,24) 
17) n          ! y/n -> 3d(with theta_dot)/2d(without theta_dot) run 
18) 1800       ! First timestep in seconds
19) 300        ! Second timestep in seconds

Remarks:

1. Name of input NetCDF file
2. Name of output NetCDF file; it is a copy from input file with the positions at noon or synoptical time added

Input Files

Dimensions:

• time

• optional a level dimension (e.g. press, theta, zeta, alt, hgt); The name of this dimension is specified in line 5 of add_noonpos.inp, specify "NONE" if there is no level dimension

Coordinate variables:

• time(time) in julian seconds

Variables:

• latitude (e.g. LAT,latitude), the name is specified in line 6 of add_noonpos.inp.
  Possible dimensions of latitude are (time), (level,time) or (time,level)

• longitude (e.g. LON,longitude), the name is specified in line 7 of add_noonpos.inp.
  Possible dimensions of longitude are (time), (level,time) or (time,level)

• theta (e.g. theta,THETA,THETA_UKMO), the name is specified in line 8 of add_noonpos.inp.
  Possible dimensions of theta are (theta), (time), (time,level), (level,time)

• zeta (e.g. zeta,ZETA), the name is specified in line 9 of add_noonpos.inp. The input file must contain the variable zeta, if "y" is specified in line 4.
  Possible dimensions of zeta are (time), (time,level), (level,time)
