everything filled in except dummy data part

dummy data part replacement? => open meteo api:
import requests
import numpy as np
import pandas as pd # Might be useful for processing time series data
from datetime import datetime, timedelta, timezone # For handling time
import pytz # For timezone handling

--- Configuration (Add your location and API details) ---

OPENMETEO_API_URL = "https://archive-api.open-meteo.com/v1/archive" # Example historical data endpoint

Replace with the actual latitude and longitude for your location

LATITUDE = 52.52
LONGITUDE = 13.41

Specify the weather parameters you need (temperature and pollutants)

Refer to Open-Meteo documentation for available parameters.

Parameters for temperature and pollutants:

- temperature_2m

- pm10

- pm2_5

- carbon_monoxide

- ... other pollutants if your model uses them

WEATHER_PARAMETERS = ["temperature_2m", "pm10", "pm2_5", "carbon_monoxide"]

You might need to specify the data interval (e.g., "hourly")

DATA_INTERVAL = "hourly"

Timezone for the location

TIMEZONE = "auto" # Or a specific timezone like "Europe/Berlin"
