******************************* | ||
** TEB simple driver version ** | ||
******************************* | ||
|
||
METEO-FRANCE / CNRS | ||
|
||
Version October 2013 | ||
|
||
|
||
contact : Valéry Masson ([email protected]) | ||
|
||
|
||
This simple driver for the TEB model (Building Energy Balance; | ||
Masson 2000 and subsequent papers), is intended to be used by scientists | ||
whishing to implement TEB in their own software. This simple driver | ||
provides all the source code of TEB alone, making it easier to analyse | ||
and to integrate in its own atmospheric model for example. | ||
|
||
If you wish to use TEB for physical simulations, wihtout intention to extract | ||
all the TEB routines into another software environment, you could use the | ||
SURFEX platform. It contains TEB and much more, especially the ISBA scheme | ||
for vegetation, or several I/O formats, including Netcdf. | ||
(http://www.cnrm.meteo.fr/surfex/) | ||
|
||
Please refer to this website for the complete documentation on TEB. | ||
|
||
-------------------------------------------------------------------------------- | ||
-------------------------------------------------------------------------------- | ||
Physical description of TEB | ||
-------------------------------------------------------------------------------- | ||
-------------------------------------------------------------------------------- | ||
|
||
The present simple "driver" version of TEB is based on : | ||
|
||
------------------------------------------------------------ | ||
version7_3 of SURFEX code; branch TEB_DEV_1514, release 1550 | ||
------------------------------------------------------------ | ||
|
||
|
||
The following physical features are included : | ||
|
||
1) Historical version of TEB (Masson 2000) : | ||
- canyon shape geometry | ||
- isotropic direction of roads | ||
- 3 energy balances for roofs, roads and walls layers | ||
- simplified internal temperature evolution (force-restore) | ||
- water reservoirs on roofs and roads | ||
- snow mantel on roofs and roads | ||
|
||
2) Building Energy Module (BEM) (Bueno et al 2012 doi:10.5194/gmd-5-433-2012) | ||
- adds Internal Building Energy Balance | ||
- adds floor and building mass energy balances | ||
- windows | ||
- Heat-Ventilation-air-Conditionning (HVAC) systems | ||
- inflitration / ventilation | ||
- solar protections | ||
- natural ventilation (opening of windows) | ||
|
||
3) Roads orientation (Lemonsu et al 2012, DOI 10.1007/s10584-012-0521-6) | ||
- possibility to use a specified road orientation | ||
(instead of a genericisotropic roads) | ||
- possibility to separate the 2 facing walls energy balances | ||
(then one have energy balances for walls 'A' and 'wall 'B') | ||
|
||
4) Garden (Lemonsu et al 2012, DOI 10.1007/s10584-012-0521-6) | ||
- possibility to add a fraction of gardens inside the canyon itself | ||
(modifies all energetic exchanges within the canyon) | ||
==> The garden needs its own vegetation energy balance. In this driver version, | ||
a simple proxi is used (based on fixed albedo and Bowen ratio) | ||
|
||
5) Greenroofs (De Munck et al 2013) | ||
- possibility to add greenroofs on the roofs | ||
==> The greenroof needs its own vegetation energy balance. In this driver version, | ||
a simple proxi is used (based on fixed albedo and Bowen ratio) | ||
|
||
6) Irrigation and solar panels (DeMunck 2013 and Masson 2013) | ||
- possibility to have irrigation of greenroofs, gardens and watering of roads | ||
- possibility to have solar panels (hot water and/or photovoltaic) | ||
|

Technical description of the driver structure | ||
-------------------------------------------------------------------------------- | ||
-------------------------------------------------------------------------------- | ||
|
||
'src_teb' directory contains the physical sources of TEB | ||
==> If you wish to implement TEB into your own software (e.g. atmospheric model) | ||
You only need to use these routines | ||
|
||
'src_driver' directory contains the routines of the driver environment | ||
==> Among these routines, you should only look at the driver.F90 program. | ||
This program is the main driver of this driver version of TEB. | ||
You can modify the values of the urban parameters (where indicated, | ||
from line 530 to line 865). | ||
|
||
'src_solar' directory contains a simplified sky model, that is in SURFEX, to | ||
estimate the part of the diffuse solar radiation that is near solar direction. | ||
This code is here only in order to retrieve exactly the same forcings data | ||
for TEB that what is in SURFEX (to insure that we have the same results). | ||
|
||
'src_proxi-SVAT' directory contains extremely simple vegetation models in case you | ||
use the 'garden' option or the 'greenroof' option. | ||
==> These vegetation models are very crude, and you are invited to use your own | ||
vegetation models instead (or ISBA using SURFEX if you wish). Note that the | ||
physical varaibles that need to be exchanged between TEB and these vegetation | ||
model (either on roofs or gradens) are only those that are in arguments of | ||
the routines in 'src_proxi-SVAT'directory. | ||
|
||
'input' directory contains data from the CAPITOUL experiment (Masson et al 2008), | ||
that is used as a test case. | ||
|
||
'output' directory contains the results of your run once you have executed driver.exe | ||
|
||
'output_ref' contains the results you should obtain, in order to check that everthing | ||
went well when you first ran driver.exe (do not change the urban parameters | ||
and options in driver.F90 if you want to do this). | ||
|
||
-------------------------------------------------------------------------------- | ||
-------------------------------------------------------------------------------- | ||
How to use the TEB driver program ? | ||
-------------------------------------------------------------------------------- | ||
-------------------------------------------------------------------------------- | ||
|
||
1) You first need to create the makefile | ||
------------------------------------- | ||
|
||
To do this, you have to: | ||
|
||
a) define your fortran compiler options in file gfortran_args | ||
b) run the script this way : | ||
|
||
mkmf.pl -t gfortran_args -p driver.exe src_driver src_proxi_SVAT src_solar src_teb | ||
|
||
c) You now should have a 'Makefile' file in your directory | ||
|
||
Documentation on this mkmf.pl makefile creation tool is provided in mkmf.html | ||
|
||
|
||
2) Compiling of the code | ||
--------------------- | ||
|
||
Just use the command : | ||
make | ||
|
||
This will compile all the routines and create the executable file driver.exe | ||
|
||
3) Running TEB ! | ||
----------- | ||
|
||
Just use the command : | ||
driver.exe | ||
|
||
The driver program should be running and show prints on your window like this: | ||
|
||
17994/17999 | ||
17995/17999 | ||
17996/17999 | ||
17997/17999 | ||
17998/17999 | ||
17999/17999 | ||
|
||
-------------------------- | ||
| DRIVER ENDS CORRECTLY | | ||
-------------------------- | ||
|
||
4) Looking at the results | ||
---------------------- | ||
|
||
Just go to the 'output' directory. It contains the temporal evolution of | ||
a few of TEB variables : | ||
|
||
RN_TOWN.txt : Net radiation (W/m²) | ||
H_TOWN.txt : sensible heat flux (W/m²) | ||
LE_TOWN.txt : latent heat flux (W/m²) | ||
|
||
P_CANYON.txt : pressure at road level (Pa) | ||
Q_CANYON.txt : specific humidity in canyon (kg/kg) | ||
T_CANYON.txt : air temperature in canyon (K) | ||
U_CANYON.txt : Wind strength in canyon (m/s) | ||
|
||
TI_BLD.txt : Internal building temperature (K) | ||
T_ROAD1.txt : road surface temperature (K) | ||
T_ROOF1.txt : roof surface temperature (K) | ||
T_WALLA1.txt : wall surface temperature (wall A) (K) | ||
T_WALLB1.txt : wall surface temperature (wall B) (K) | ||
|
||
|
||
If BEM option is activated, you also have these outputs: | ||
W / m² of buildings ground surface (not by m² of floor) | ||
|
||
HVAC_COOL.txt : Cooling Energy Demand | ||
HVAC_HEAT.txt : Heating Energy Demand | ||
|
||
|
||
5) Enjoy | ||
----- | ||
|
||
You can now modify the urban options and parameters in driver.F90 in order | ||
to see their impacts. | ||
|
||
|
||
6) If you want to change the atmospheric forcing data | ||
-------------------------------------------------- | ||
|
||
a) change the characteristics of your forcing in driver.F90 (lines 97 to 107) | ||
b) change the forcing data in the 'input' directory, but you should use the same | ||
type of text files | ||
c) run driver.exe | ||
|
||
|
||
7) If you want to implement TEB in your own software | ||
------------------------------------------------- | ||
|
||
All the TEB sources you need are in the 'src_teb' directory. | ||
|
||
|
||
-------------------------------------------------------------------------------- | ||
-------------------------------------------------------------------------------- | ||
End. Have fun with TEB. | ||
