Request for Archive Samples

The NADP receives requests for sample materials received through the operation of the NADP Analytical Laboratory (NAL).  These samples are made available to external researchers and internal NADP sanctioned research to support the NADP mission as outlined in the NADP Governance Document. 

The Sample Archive Policy and Request document describes how external and internal researchers may request NADP sample materials and how those requests are evaluated, approved, costed, and fulfilled by the NADP Program Office (PO) and the NADP Analytical Laboratory (NAL).

Sample matrices that may be available include:

• National Trends Network (NTN) precipitation samples (pre- or post-filtered), including archived precipitation samples
• NTN filters
• Mercury Litterfall Network (MLN) sample material (when applicable)

Researchers interested in analyzing archived NADP samples should contact Sarah Benish, NADP PI/Coordinator.
