Notes

1. Demonstration of pyopencdms

Ian gave a demonstration of the pyopencdms package. A summary of the code shown in the meeting is below:

import os
from pathlib import Path

import opencdms

from opencdms import Climsoft4, MCH, MidasOpen

from opencdms import MidasOpen

connection = os.path.join(
    Path.home(), 'opencdms-dev', 'git', 'opencdms-test-data')

connection

'/home/ubuntu/opencdms-dev/git/opencdms-test-data'

session = MidasOpen(connection)

filters = {
    'src_id': 838,
    'period': 'hourly',
    'year': 1991,
    'elements': ['wind_speed', 'wind_direction'],
}

filters

{'src_id': 838,
 'period': 'hourly',
 'year': 1991,
 'elements': ['wind_speed', 'wind_direction']}

# obs = session.obs(src_id=838, period='hourly', year=1991, element=['wind_speed', 'wind_direction'])

obs = session.obs(**filters)
