Code Example :

Hourly Variables

from openmeteopy import OpenMeteo
from openmeteopy.options import EcmwfOptions
from openmeteopy.hourly import HourlyEcmwf
from openmeteopy.utils.constants import *

# Latitude, Longitude 
longitude = 33.89
latitude =  -6.31

hourly = HourlyEcmwf()
# Here we want to see the data of past days too,notice how the timezone parameter is non existent for these api options
options =  EcmwfOptions(latitude, 
                        longitude, 
                        past_days=2)

mgr = OpenMeteo(options, hourly.all())

# Download data in json format
meteo = mgr.get_json_str()

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
