Solar Radiation

Author

Gorton, Bec (Environment, Hobart)

The solar radiation data can be provided in two possible formats:

Time Series file (.ts)

This is the traditional method that has been used in past models. This format allows the modeller to provide a single value for the entire model for a given timestamp.

Sample forcing file parameters:

Solar_radiation inputs/GladstoneSolar.ts
Solar_radiation_rewind 1

Data Format:

## COLUMNS 2

##
## COLUMN1.name Time

## COLUMN1.long_name Time
## COLUMN1.units days since 1990-01-01 00:00:00 +10

## COLUMN1.missing_value -999.000000
##
## COLUMN2.name swr

## COLUMN2.long_name Short wave radiation
## COLUMN2.units W m-2

## COLUMN2.missing_value -999.000000
##
366 201.6875
367 167.458328
368 106.75
369 175.104172
......

NetCDF File (.nc)

This is new functionality in the Atlantis trunk code from 10th September 2015. This format allows modellers to provide a value per box.

Sample forcing file parameters:

Solar_radiation inputs/Gladstone305_6HourSWR.nc
Solar_radiation_rewind 1

The Atlantis code will check to see if the Solar_radiation file name ends with ts or nc to work out what type of file is provided.

Data Format:

netcdf Gladstone305_6HourSWR {
dimensions:
    t = UNLIMITED ; // (120 currently)
    b = 305 ;
variables:
    double t(t) ;
        t:units = "seconds since 2010-01-01 00:00:00 +10" ;
        t:dt = 21600. ;
    double swr(t, b) ;
        swr:_FillValue = 0. ;
// global attributes:
        :title = "swr data for Gladstone Atlantis model." ;
        :geometry = "GHHP_xy_0p0001_July.bgm" ;
        :parameters = "" ;
}
