air-db

air-db is a data access layer (DAL) to easily query atmospheric time series datasets from various sources. air-db does not include any database. It is required to install corresponding database to work air-db properly.

To install sample database:

from airdb import Database

Database.install_sample()

A database query can be implemented as follows:

from airdb import Database

db = Database('samp', return_type='df')

q = db.query(param=['so2', 'pm10'], city='istanbul', date=['>2010-05-10', '<2012-10-07'], month=5)

print(q)

del db  # close connection to database

and the output is:
