Here’s an example of requesting all measurements for a station’s latest observation:

from historical_obs_sqlalchemy import Station

station = Station.by_id('my-station-of-interest')
observation = station.latest_observation()
measurements = observation.measurements()

If we were only interested in precipitation and temperature for this observation, we can use our parameters filter:

measurements = observation.measurements(parameters=['precipitation', 'temperature'])

Parameters:(optional) (parameters) – a list of parameters to filter.

recorded_at

The time the observation took place.

save()

Saves the observation.

station = None
