Notes

The daily elaborated series (QmnJ) is the publisher’s own aggregation of its sub-hourly record, so Hydrionis takes it rather than recomputing a daily mean from instantaneous values it would have to interpolate.

What Hydrionis uses it for

653,271 observations across 1 metrics currently reference this source.
