4.5. CBL input files¶
Main references for this part of the model: Onomura et al. (2015) [Shiho2015] and Cleugh and Grimmond (2001) [CG2001].
If CBL slab model is used (CBLuse = 1 in
RunControl.nml) the following files are needed.
| Filename | Purpose |
|---|---|
| CBL_initial_data.txt | Gives initial data every morning * when CBL slab model starts running. * filename must match the InitialData_FileName in CBLInput.nml * fixed formats. |
| CBLInput.nml | Specifies run options, parameters and input file names. * Can be in any order |
4.5.1. CBL_initial_data.txt¶
This file should give initial data every morning when CBL slab model starts running. The file name should match the InitialData_FileName in CBLInput.nml.
Definitions and example file of initial values prepared for Sacramento.
| No. | Column name | Description |
|---|---|---|
| 1 | id | Day of year [DOY] |
| 2 | zi0 | Initial convective boundary layer height (m) |
| 3 | gamt_Km | Vertical gradient of potential temperature (K m-1) strength of the inversion |
| 4 | gamq_gkgm | Vertical gradient of specific humidity (g kg-1 m-1) |
| 5 | Theta+_K | Potential temperature at the top of CBL (K) |
| 6 | q+_gkg | Specific humidity at the top of CBL (g kg-1) |
| 7 | Theta_K | Potential temperature in CBL (K) |
| 8 | q_gkg | Specific humidiy in CBL (g kg-1) |
- gamt_Km and gamq_gkgm written to two significant figures are required for the model performance in appropriate ranges [Shiho2015].
