Raspberry Pi Weather Forecast-Setup/Instructions



This instructions assume your Raspberry Pi is already up and running/

Section 1. Download and install Docker on your Raspberry Pi

The WRF application is run through a program called Docker. It is too complicated for this lesson on how Docker works, but a good description can be found here. Once you have docker installed onto your computer, it will be very easy to launch the application on your raspberry pi. 

1.1 Install docker by opening a terminal and typing

curl -sSL https://get.docker.com | sh

1.2 Launch the application by copying and pasting the following command

sudo docker run -it --rm --net=host -e DISPLAY -v $HOME/.Xauthority:/root/.Xauthority ncar/pi-wrf​​​​​​​

When you enter the following command and execute it, the Docker then downloads the file for your and then launches it. If you close the program Docker will save the “file” so you do not have to download it next time you decide to run the application.


Section 2:
Once you have launched the application, it is time to run it. The app allows you to configure when you wan the model to run and for how long. Follow the following steps to make your first fircast.

2.1 Click on the Run Forecast Button

2.2. Select a start and end date, and confirm selection.

2.3 Click and drag the domain you would like to select. The map automatically zooms to your domain. If you accidentally choose a domain that is too small, then you may either zoom out or reset the domain. Once you are done, click the run model tab.

2.4. Press the run model button when you are ready to run the model. After the model finishes, a button will appear to view the ouput. Click it to see the results of the model.
