1To activate time series output in WRF, a file named "tslist" must be present
2in the WRF run directory. The tslist file contains a list of locations, given
3by their latitude and longitude, along with a short description and an
4abbreviation for each location. The first three lines in the file are
5regarded as header information, and are ignored. The contents of an example
6tslist file are shown below.

18Given a tslist file, for each location inside a model domain (either coarse
19or nested) a file containing time series variables at each time step will be
20created with the name pfx.dNN.TS, where pfx is the specified prefix for the
21location in the tslist file, and NN is the domain ID, as given in
22namelist.input. If locations not in any model domain are specified in the
23tslist file, they will be simply ignored by the time series capability.
24
25The maximum number of time series locations is controlled by the namelist
26variable max_ts_locs, which may be specified in the &domains namelist. Also,
27the number of entries in the buffers for time series output can be set with
28the ts_buf_size variable, also found in &domains. Decreasing the size of the
29buffers will reduce the amount of memory that is allocated for time series;
30however, smaller buffers will need to be flushed to disk more often than
31larger buffers. Thus, it is recommended that the size of the buffer be set
32to the maximum number of time steps for any domain in a model run.

35The first line in a time-series output looks like this:
36
37NZCM McMurdo               2  7 mcm   (-77.850, 166.710) ( 153, 207) (-77.768, 166.500)   81.8 meters
38
39Those are name of the station, grid ID, time-series ID, station lat/lon, grid indices (nearest grid point to
40the station location), grid lat/lon, elevation.
41
42The variables from the time series output are:
43
44id, ts_hour, id_tsloc, ix, iy, t, q, u, v, psfc, glw, gsw, hfx, lh, tsk, tslb(1), rainc, rainnc, clw
45
46id:             grid ID
47ts_hour:        forecast time in hours
48id_tsloc:       time series ID
49ix,iy:          grid location (nearest grid to the station)
50t:              2 m Temperature (K)
51q:              2 m vapor mixing ratio (kg/kg)
52u:              10 m U wind (earth-relative)
53v:              10 m V wind (earth-relative)
54psfc:           surface pressure (Pa)
55glw:            downward longwave radiation flux at the ground (W/m^2, downward is positive)
56gsw:            net shortwave radiation flux at the ground (W/m^2, downward is positive)
57hfx:            surface sensible heat flux (W/m^2, upward is positive)
58lh:             surface latent heat flux (W/m^2, upward is positive)
59tsk:            skin temperature (K)
60tslb(1):        top soil layer temperature (K)
61rainc:          rainfall from a cumulus scheme (mm)
62rainnc:         rainfall from an explicit scheme (mm)
63clw:            total column-integrated water vapor and cloud variables
