Get Values with Time range
We have two others endpoints that give hourly and daily aggregates. Since we are dealing with dense time series (with a fixed timestep), I use a compact storage for the time serie data. An hourly resource represent one day of hourly data as an array of 24 values. A daily resource represent one year of daily data as an array of 365/366 values.
https://api.iwqis.iowawis.org/v1/hourly?site_uid=WQS0020&begin=2017-04-01&end=2017-04-20
where "begin" and "end" dates are in YYYY-MM-DD format.
https://api.iwqis.iowawis.org/v1/daily?site_uid=WQS0020¶m_uid=discharge&begin=2016&end=2017
where "begin" and "end" are YYYY.
