.SH DESCRIPTION |
| 32 |
|
.I Gensdaymtx |
| 33 |
|
takes a weather tape as input and produces a matrix of spectral sky patch |
| 34 |
|
values using the precomputed atmospheric scattering model. |
| 35 |
+ |
Unlike the similarly-named |
| 36 |
+ |
.I gendaymtx |
| 37 |
+ |
tool, the Perez sky model is not used. |
| 38 |
|
The weather tape is assumed to be in a special form of the .wea file, which contains |
| 39 |
|
a short header with the site parameters followed |
| 40 |
|
by the month, day, standard time, direct normal and diffuse horizontal |
| 41 |
< |
irradiance values, total cloud cover, and broadband aerosol optical depth, one time step per line. |
| 41 |
> |
illuminance values, total cloud cover, and broadband aerosol optical depth, one time step per line. |
| 42 |
> |
Alternatively, a standard EPW (EnergyPlus Weather) file may be provided. |
| 43 |
|
Such file can be generated by |
| 44 |
|
.I epw2wea |
| 45 |
< |
with appending |
| 45 |
> |
with the |
| 46 |
|
.I \-a |
| 47 |
|
flag. |
| 48 |
|
Each time step line is used to compute a column in the output matrix, |
