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

18 | Given a tslist file, for each location inside a model domain (either coarse |
---|
19 | or nested) a file containing time series variables at each time step will be |
---|
20 | created with the name pfx.dNN.TS, where pfx is the specified prefix for the |
---|
21 | location in the tslist file, and NN is the domain ID, as given in |
---|
22 | namelist.input. If locations not in any model domain are specified in the |
---|
23 | tslist file, they will be simply ignored by the time series capability. |
---|
24 | |
---|
25 | The maximum number of time series locations is controlled by the namelist |
---|
26 | variable max_ts_locs, which may be specified in the &domains namelist. Also, |
---|
27 | the number of entries in the buffers for time series output can be set with |
---|
28 | the ts_buf_size variable, also found in &domains. Decreasing the size of the |
---|
29 | buffers will reduce the amount of memory that is allocated for time series; |
---|
30 | however, smaller buffers will need to be flushed to disk more often than |
---|
31 | larger buffers. Thus, it is recommended that the size of the buffer be set |
---|
32 | to the maximum number of time steps for any domain in a model run. |
---|
33 | |
---|
34 | |
---|
35 | The first line in a time-series output looks like this: |
---|
36 | |
---|
37 | NZCM McMurdo 2 7 mcm (-77.850, 166.710) ( 153, 207) (-77.768, 166.500) 81.8 meters |
---|
38 | |
---|
39 | Those are name of the station, grid ID, time-series ID, station lat/lon, grid indices (nearest grid point to |
---|
40 | the station location), grid lat/lon, elevation. |
---|
41 | |
---|
42 | The variables from the time series output are: |
---|
43 | |
---|
44 | id, ts_hour, id_tsloc, ix, iy, t, q, u, v, psfc, glw, gsw, hfx, lh, tsk, tslb(1), rainc, rainnc, clw |
---|

47 | ts_hour: forecast time in hours |
---|
48 | id_tsloc: time series ID |
---|
49 | ix,iy: grid location (nearest grid to the station) |
---|
50 | t: 2 m Temperature (K) |

51 | q: 2 m vapor mixing ratio (kg/kg) |
---|
52 | u: 10 m U wind (earth-relative) |
---|
53 | v: 10 m V wind (earth-relative) |

55 | glw: downward longwave radiation flux at the ground (W/m^2, downward is positive) |
---|
56 | gsw: net shortwave radiation flux at the ground (W/m^2, downward is positive) |
---|
57 | hfx: surface sensible heat flux (W/m^2, upward is positive) |
---|
58 | lh: surface latent heat flux (W/m^2, upward is positive) |
---|
59 | tsk: skin temperature (K) |
---|
60 | tslb(1): top soil layer temperature (K) |
---|
61 | rainc: rainfall from a cumulus scheme (mm) |
---|
