Open data weather forecasts from the German weather service DWD

Code Example :

from openmeteo_py import OWmanager
from openmeteo_py.Hourly.HourlyDwd import HourlyDwd
from openmeteo_py.Daily.DailyDwd import DailyDwd
from openmeteo_py.Options.DwdOptions import DwdOptions
from openmeteo_py.FifteenMinutes.FifteenMinutesDwd import FiftennMinutesDwd


# Latitude, Longitude 
longitude = 139.817413
latitude =  35.672855	

hourly = HourlyDwd()
daily = DailyDwd()
minutes_15 = FiftennMinutesDwd()
options = DwdOptions(latitude,longitude)

mgr = OWmanager(options,OWmanager.dwd_icon,hourly.all(),daily.all(),minutes_15.all())


# Download data
meteo = mgr.get_data()

print(meteo)

Pressure Level Variables

Pressure level variables do not have fixed altitudes. Altitude varies with atmospheric pressure. 1000 hPa is roughly between 60 and 160 meters above sea level. Estimated altitudes are given below. Altitudes are in meters above sea level (not above ground). For precise altitudes, geopotential_height can be used.

Variable Unit
weathercode WMO code
temperature_1015hPa ... temperature_10hPa °C (°F)
relativehumidity_1015hPa ... relativehumidity_10hPa %
dewpoint_1015hPa ... dewpoint_10hPa °C (°F)
cloudcover_1015hPa ... cloudcover_10hPa %
windspeed_1015hPa ... windspeed_10hPa km/h (mph, m/s, knots)
winddirection_1015hPa ... winddirection_10hPa °
geopotential_height_1015hPa ... geopotential_height_10hPa meter

Pressure level methods

to call a pressure level method all you have to do is put the variable for example ; temperature then an underscore _ and the equivalent pressure level for example : 1015hpa

for this example the method is temperature_1015hpa()

pressure - elevation equivalent
