slr.cli and slr data files

These files contain all information needed by the model about observed solar radiation data.

The solar radiation data files contain the observed precipitation input data. They are named by the user and must have the file ending *.slr. There must be one file per station used in the simulation. As in all SWAT+ input files, the first line in the solar radiation data files is reserved for user comments. The second line contains the column headers for the third line, which lists basic information about the station.

Field	Description	Type	Unit
nbyr	Length of the solar radiation time series	integer	years
tstep	Time step of the solar radiation data	integer	n/a
lat	Latitude of the solar radiation station	real	Decimal Degrees
lon	Longitude of the solar radiation station	real	Decimal Degrees
elev	Elevation of the solar radiation station	real	m

Starting in the fourth line, the year, Julian day, and solar radiation are listed. There are no headers for these columns.

Field	Description	Type	Unit
year	Year of the observation	integer	n/a
jday	Julian day of the observation	integer	n/a
slr	Observed solar radiation	real	MJ/m^2/day

A negative 99.0 (-99.0) should be inserted for missing data. This value tells SWAT+ to generate a solar radiation value for that day.

The slr.cli file lists the names of the solar radiation data files used in the simulation. The first line is reserved for user comments. The second line is reserved for the column header "filename". The user can list as many solar radiation data file names as needed for the simulation. Only one file name should be listed per line. All file names listed in weather-sta.cli must be listed here. For every file name listed in slr.cli, a file with that name must be provided by the user that contains the solar radiation data measured at the station.
