• Uzip the downloaded RETIGO format file to a location on your computer.
• From the "Quick Links" box on the side of the main page choose "Enter your data in RETIGO".
• From the "View a data file section" select the bullet next to "Your file:" and click the "Choose File" button.
• Navigate to the folder on your computer with the unzipped RETIGO format file, select it and choose "Open"
• Click "View"
• A color coded map of the sensors should appear.
• To the right of the map are some controls.
• • You may want to change the high end of the data range to something like 40 or so to make the color range more meaningful.
  • You can check the box for "Show timeseries plot" or "Show wind-pollution plot".
  • You can change the Time range from the default "Avg" to "block" and choose a different value for "Extend blocks".
  • At the top of the controls you will see a map pin icon (next to the hand icon). Click on the pin icon and then on the map to set a pin. Then check "Show analysis plot" which will show a graph of readings and their distance from the pin.
