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
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.
The Ammonia Monitoring Network is the NADP's newest network. The AMoN reports atmospheric ammonia concentrations to determine ammonia dry deposition.
The AMNet reports atmospheric mercury concentrations for determination of mercury dry deposition.
NADP is modernizing its equipment.
