Plots the vertical atmospheric structure as plots between Altitude and Temperature and Altitude vs. wind speed using aircraft data collected from the dump1090-fa ADSB decoder. The calculations are similar to those used in the tar1090 package.
Reads data from history_xx.json files generated by dump1090-fa and calculates the following meteorologic parameters:
- Wind Speed (WS)
- Outside Air Temperature (OAT)
- Installation:
-
Clone/Download this repo.
-
Open the terminal and navigate to the folder downloaded folder.
-
Make the meteo_adsb.sh script executable using the following command:
bash chmod +x meteo_adsb.sh
- Open the terminal and run the command to install Meteo-ADSB:
sudo ./meteo_adsb.sh -i
The script will prompt you to configure the source directory for JSON data. You can choose to run the ADSB decoder locally or on a remote machine.
sudo ./meteo_adsb.sh -r
- This will start a local server on port 5050, which is accessible at http://DEVICE_LOCAL_IP:5050.
The webpage will generate
- Altitude vs. temperature
- Altitude vs. wind speed
- Map of Aircraft data sampling locations
You can use these plots to analyze the vertical atmospheric structure in the area where the data was collected. For example, you can look at how the temperature and wind speed change with altitude.
Altitude vs. temperature: The temperature generally decreases with height. However, there can be inversions, where the temperature increases with altitude. Inversions can trap pollutants and cause decreased air quality. The lapse rate can also be used to study the local moisture convection.
Altitude vs. wind speed: The wind speed generally increases with altitude. However, there can be low-level winds, which are caused by surface friction which can be used to understand the planetary boundary layer.
