This is a script that extracts weather data from the Open-Meteo API and plots it as a graph.

To run the code, you need to install the following python packages:

requests
argparse
matplotlib

You can install these packages by running

pip install -r requirements.txt

Or by manually installing them with pip install

The code uses data from the Open-Meteo API. A link to their API can be found here: https://open-meteo.com/en/docs.

You need to run the code directly from the command-line interface (CLI). It can be run by typing:

python main.py [latitude] [longitude] [category] --current_weather 1

[latitude] is a float value between -90 and 90
[longitude] is a float value between -180 and 180
[category] is a string that selects which weather data to display. The supported categories from the API are found in the official documentation of Open-Meteo API https://open-meteo.com/en/docs under Hourly Parameter Definition.
--current_weather 1 is an optional argument and provides printout of the current weather to your terminal.

You can also get information by running python main.py -h or python main.py --help in your command line. \

Some examples to show how to use the code:

Output of python main.py 25.2 10 temperature_2m:

You have entered the following coordinates: (25.2N, 10.0E)
Selected category for weather data: temperature_2m
Generating weather data for temperature_2m at coordinates (25.2N, 10.0E)...

Finishing generating after 8.613 ms!
Plotting data...
Success!

Output of python main.py 3.2 4.5 windspeed_10m:

An example of running python main.py 25.2 10 temperature_2m --current_weather 1 will print something like this in your terminal in addition to the plot in the first example:

You have entered the following coordinates: (25.2N, 10.0E)
Selected category for weather data: temperature_2m
Generating weather data for temperature_2m at coordinates (25.2N, 10.0E)...

CURRENT WEATHER FOR (25.2N, 10.0E):
Current time: 2022-01-27T09:00
Current temperature: 8.9 °C
Current windspeed: 13.5 km/h
Current wind direction: 135° 

Finishing generating after 8.613 ms!
Plotting data...
Success!

If you have specified an unsupported category the following message will appear in your terminal:

python main.py 25.2 10 temperature
You have entered the following coordinates: (25.2N, 10.0E)
Selected category for weather data: temperature
