|
| Data are unaggregated and reported in the same time intervals as collected at CASTNET sites. Data types include weekly filter pack concentrations and hourly meteorological, ozone and trace gas measurements. |
|
| Data are measured concentrations for each pollutant averaged over weekly, seasonal, or annual time periods. In addition, users can download ozone 8-hour daily maximum or W126 values. |
|
| Data include estimated hourly dry deposition rates and fluxes aggregated by week, season or year. Dry deposition velocity estimates are from the Multi-Layer Model (MLM), a dry deposition model. Missing deposition velocities have been replaced with historical averages. Dry deposition flux is calculated from the estimated deposition velocity and the measured pollutant concentration.
In addition, users can download wet and total annual deposition values. Total deposition is calculated as the sum of wet deposition (as measured by NADP/NTN) and dry deposition (as measured by CASTNET). |
|
| Data include site details and parameters used as input to the Multi-Layer Model (MLM). The MLM is used to estimate deposition rates at by parameter for each CASTNET site. |
|
| These prepackaged datasets contain the same data as the previous four report types, but as raw csv data files for intensive data analysis. |
|
| Data are modeled using the CLOUD cloud deposition model during warm weather sampling seasons. Additional information about the cloud deposition monitoring program can be found under the Documents and Reports tab. |
