Cary Institute of Ecosystem Studies, Millbrook NY
The Cary Institute has been monitoring acidic gases and particles using a CASTNET protocol 3-stage filter pack since 1988. In addition, the monitoring site, located in Millbrook, NY, collects hourly meteorological parameters and hourly ozone data. While not part of the CASTNET monitoring program, the site is an obvious partner in dry deposition research.
Similar to the CASTNET protocol, the filters are deployed under a rain shelter at 10m from Tuesday-Tuesday. The filter packs from the Millbrook site are analyzed at the Cary Institute of Ecosystem Studies Laboratory. The meteorological data is now being processed by the Multi-Layer Model (MLM) which is also used by the CASTNET program to calculate deposition velocities. The concentration data and flux estimates from the Cary Institute can be found here on the Data Summary website.
The Cary Institute has also joined the NADP AMoN, a passive ammonia (NH3) monitoring network. Data from all AMoN sites can be found on the NADP Web page. Additional monitoring at the Millbrook site includes a Climate Reference Network site and a wet precipitation site. Data from all the measurements collected at the Cary Institute site, as well as additional information about the Cary Institute Monitoring program, can be found on the their website.
