To load weather data for your location:
The Wizard comes with a large folder of weather files covering most Australian cropping regions. The installer should have placed a shortcut to the weather file directory on your desktop. To choose a weather file:
- Start the wizard.
- Open or create a Scenario.
- Press the 'Scenario setup' perspective.
- Press the 'Weather records' button.
- In the file chooser that pops up, navigate to your weather file directory and select the location you wish to use.
To update the weather data for your location:
- Download the Weather files by clicking the Download Weather Files link under the Download button.
- Save the folder in C:\Weather Files
- To get there on a normal Windows 7 PC, click Start Button → Computer → Local Disk (C:) → Weather File. If your zip program asks you what you want to do with existing files it’s best to get it to replace/overwrite the existing files.
- Alternatively, save the Weather files in a folder of your choice and once inside the Wizard, browse to use the weather file in your scenarios.
To create your own, new weather data file:
You may want to create your own weather data file. For example, you might want to use weather records from a specific farm, or a town not included in the current list of weather data files. Alternatively, you might want to try imaginary weather data, for research purposes. To create your own weather file.
- Go to Local Disk (C:) → Weather File.
- Open one of the .csv files at random. Re-save it with a new location name.
- In the file, update the 'RAIN' (daily total rainfall in mm), 'MAX_TEMP' and 'MIN_TEMP' (maximum and minimum daily temperature in degrees celcius) and 'EVAPORATION' (daily evaporation in mm) data with data from your site.
- Save the file with the updated data.
- Note that the weather files have all the historical weather records for a site. For example, 'WA_Northam.csv' has data from 1/1/1912 to the present. If using your own data, you only need to include data for the time frame of your scenario. If you're looking at a scenario from 2018 to 2021, you will only need weather data for these years. So when creating your own weather file, delete all years of data prior to 2018.
