There are two main ways to add NetCDF data in QGIS, through the add raster button, and with the NetCDF Browser plugin.

Raster

1. Download Data
   1. It is recommended to create a folder to store your data to save time from looking around generalized folders such as the download folder
2. Click on the top menu bar → Layers → Add Raster
3. NetCDF can have both single-variables or multiple variables within the file
   1. If there is only one variable, it will automatically be loaded in
   2. If there are multiple variables, you will be prompted to select the layers that you want to load in
      1. This can take the form of different variables, but each time step is also displayed as individual variables
   3. You can alter the way which a layer is displayed by accessing its style properties
      1. Right-click a layer → Properties
      2. Under the Style tab, you can specify Min/Max values, Contrast Enhancement, and Color Gradient

NetCDF Browser Plugin

1. Download Data
   1. It is recommended to create a folder to store your data to save time from looking around generalized folders such as the download folder
