Nr Deposition Science Needs White Paper

NADP's Total Deposition Science Committee (TDep) has released a white paper, Science needs for continued development of total nitrogen deposition budgets in the United States".

CAL Readiness Verification Report

The CAL Readiness Verification Report has been released

Happy 40th Anniversary to NADP!

The very first NADP samples on July 5, 1978 were from: NC25, Coweeta in Macon, NC; WV18, Parsens in Tucker, WV; MN16, Marcell Experimental Forest in Itasca, MN.

NADP has moved

The NADP Program Office (PO) and Central Analytical Lab (CAL) have moved from the University of Illinois (U of I) to their new home at the University of Wisconsin's State Laboratory of Hygiene (WSLH) in Madison, WI.

NADP Impact Statement

The NADP is the State Agriculture Experiment Station (SAES) National Research Support Program 3 (NRSP-3). SAES recently published a 2-page Impact Statement that highlights NADP’s accomplishments for the period 2009-2014.

Total Deposition Maps now Available

NADP has just released a new series of maps, which are estimates of dry plus wet deposition for sulfur and nitrogen. The maps are based on a new hybrid method of determining total deposition, which was developed within the NADP Total Deposition Science Committee (TDEP) . Check out the website for more details and to see the maps!

Litterfall Mercury Monitoring Initiative

The National Atmospheric Deposition Program (NADP) has a new litterfall mercury monitoring initiative to complement the Mercury Deposition Network (MDN) monitoring for mercury in precipitation and the Atmospheric Mercury Network (AMNet) monitoring for mercury in air

Fukushima Dai-ichi radioactive fallout detected in NADP samples

The National Atmospheric Deposition Program and the United States Geological Survey collaborated to monitor NADP precipitation samples for the presence of radioactive material in response to the Japan Fukushima Dai-ichi Nuclear Power Station incident that occurred on March 11, 2011.
