| 279 | | This example shows the output of the quantity "turbulent resolved-scale horizontal momentum flux" (u*v*). If more than one user-defined quantity shall be output, the following steps have to be carried out in the same way for each of the quantities. |
| 280 | | |
| 281 | | 1. The calculation of user-defined spectra is closely linked with the calculation of part 1. (user-defined vertical profiles) and part 3. (user-defined 3d volume data). Therefore, the following prerequisites apply for each user-defined spectra quantity: |
| 282 | | |
| 283 | | 1. From part 1. (user-defined vertical profiles) steps 2 and 3. |
| 284 | | See the sample code (as comment lines) for 'u*v*' and ustvst, respectively. (Actual output of vertical profiles - step 1 - is not required.) |
| 285 | | 2. From part 3. (user-defined 3d volume data) steps 2, 3, 4, 5, and 6. |
| 286 | | See the sample code (as comment lines) for 'u*v*' and ustvst, respectively. (Actual output of 3d volume data - step 1 - is not required.) |
| 287 | | 3. The quantity has to be given a unique string identifier, e.g. 'u*v*'. This identifier must be different from the identifiers used for the PALM standard output (see list in description of package parameter data_output_sp). To switch on output of this quantity, the user has to assign the string identifier to the package parameter data_output_sp, eg.: |
| 288 | | |
| 289 | | data_output_sp = 'u*v*' |
| 290 | | |
| 291 | | A. and B. as prerequisites for C. require a naming convention of identical identifiers, e.g. data_output_pr_user = 'u*v*', data_output_user = 'u*v*' and data_output_sp = 'u*v*'. This naming convention applies only in case of user-defined spectra. |
| 292 | | |
| 293 | | 2. Edit the subroutine user_spectra (only those parts in red) as follows: |

This identifier must be different from the identifiers used for the {{{PALM}}} standard output (see list in description of package parameter [../../sppar#data_output_sp data_output_sp]). To switch on output of this quantity, the user has to assign the string identifier to the package parameter [../../sppar#data_output_sp data_output_sp], eg.: |
