| 7 | The program read any wrf dataset in NETCDF/GRIB1 format and can produce either |
|---|
| 8 | GrADS input data format or Vis5D input format. |

|---|
| 10 | WRFV2 MUST be compiled and avaliable. If WRFV2 is not on the same level as |
|---|
| 11 | ARWpost, then configure.arwp needs to be edited to correct path. |

|---|
| 14 | COMPILE |
|---|
| 15 | ./configure --- to get a list of compile options for your computer |
|---|
| 16 | If your computer is not listed, you will need to add it under |
|---|
| 17 | arch/configure.defaults |
|---|
| 18 | ./compile --- compile the code |
|---|
| 19 | |
|---|
| 20 | ./clean -a --- clean |

| 45 | './wrfout' will read all files with root name "wrfout" |
|---|
| 46 | in the current directory |
|---|
| 47 | output_root_name :: root name of output files |
|---|
| 48 | for grads output 2 files will be created |

|---|
| 93 | For 1, must specify levels in 'interp_levels' |
|---|
| 94 | interp_levels :: Only used if 'interp_method = 1' |
|---|
| 95 | Height (km) or Pressure (hPa) |
|---|

|---|
| 136 | TO ADD DIAGNOSTICS |
|---|
| 137 | First make sure that all the arrays needed for the calculations are |
|---|
| 138 | available. The following are carried NOW. |
|---|
| 139 | XLAT, XLONG, HGT, PSFC, P, PB, PH, PHB, QV, T(theta-300), TT(temp in K from metdata) |
|---|
| 140 | U10, V10, UUU, VVV (if keep_wind_arrays = TRUE) |
|---|
| 141 | QR, QS, QG (if keep_moist_arrays = TRUE) |
|---|
| 142 | |
|---|
| 143 | Logical variables have_* indicate if arrays are present. |
|---|
| 144 | |
|---|
| 145 | See src/module_model_basics.f90, and src/module_arrays.f90 |
|---|
| 146 | |
|---|
| 147 | Create a new module (module_calc_*.f90) which will calculate the new |
|---|
| 148 | diagnostic variable. Look at one of the existing ones for an example. |
|---|
| 149 | |
|---|
| 150 | Add CALL to src/module_diagmostics.f90 |
|---|
| 151 | Must call the following 3 routines |
|---|
| 152 | CALL calc_* (new diagnostics) |
|---|
| 153 | CALL interp (to interpolate to output grid) |
|---|
| 154 | CALL write_dat (to write output) |
|---|
| 155 | |
|---|
| 156 | Make appropriate changes to the Makefile |
|---|
| 157 | |
|---|
| 158 | If a new 3D diagnostical field had been created, AND Vis5D output are |
|---|
| 159 | going to be generated, this new field must also be added to "known_3d_fields" |
|---|
| 160 | in src/v5d_module.f90 |
|---|
| 161 | |
|---|
| 162 | |
|---|
| 163 | Special NOTES: |
|---|
| 164 | Vis5D output, cannot have 'plot = "all"' |
|---|
