Station lagged alt​. check

The Station Comparison check compares the individually configured volume, energy, mass, pressure and/or temperature of the selected station or stations to the tolerance percentages selected, within the hours specified in Lag Time (hrs.).

This test is used to validate data. The check is performed on the primary granularity of the designated stations.

The Lag Time (hrs.) specifies the time back from the primary granularity record that the check will run against. For an explanation of Lagged Alternate, see Historical Lagged alternate measurement estimate.
