Show Incomplete Data:

Caution: This option may include data which the NADP has determined to be invalid. Concentrations and depositions for invalid samples are shown. This file includes samples which are grossly contaminated, there was a serious breach of protocol in the collection and analysis of this sample, or both. These samples can be identified by the qrCode field, which will have a value of "C".

Caution: This option may include data that does not meet NADP's minimum criteria for data completeness:

At least 75% of time period is represented by valid samples
Precipitation amount is known for at least 90% of the period
At least 75% of the total measured precipitation is represented by valid samples

Annual Criteria:

The annual weighted mean concentrations and depositions are characterized as meeting or not meeting the NADP's data completeness criteria for each 1-year period.

Valid samples for 75% of the time period
Valid samples for 90% of the precipitation amount
Precipitation amounts for 75% of the time period

Trend line:

The trend line is a smoothed 3-yr moving average with a one-year time step. The line is only displayed where the minimum data completeness criteria is met for the 3-year period.
