South Florida/Caribbean Network

Overview

The South Florida/Caribbean Vital Signs Network (SFCN) consists of six NPS units. The parks include cultural, historical and natural areas. Everglades NP and Virgin Islands NP are designated Class I air quality areas; the rest of the parks are Class II areas.

Air quality is monitored in Everglades NP and Virgin Islands NP. Both parks monitor visibility conditions and wet atmospheric deposition. Ozone and mercury deposition are also monitored in Everglades NP. Mercury deposition is significantly elevated in Everglades NP and has resulted in accumulation of mercury in park fish and wildlife.

The Network map below provides information on air quality monitoring. Ozone, sulfur dioxide, dry deposition, and meteorology are collected by the Clean Air Status and Trends (CASTNet) and Gaseous Pollutant Monitoring (GPMN) networks. Ozone is also monitored with passive samplers and portable continuous analyzers. Wet Deposition is monitored through cooperation with National Atmospheric Deposition Program/National Trends Network (NADP/NTN). The Mercury Deposition Network (MDN), part of NADP, collects precipitation samples that are analyzed for mercury. Visibility is monitored as part of the Interagency Monitoring of Protected Visual Environments (IMPROVE). Additional details on these parameters are described in Air Quality Monitoring.

Air quality monitoring in or near the network is indicated on the map by symbols, with the blue line showing the approximate borders of the network. The legend shows the symbols for the type of monitoring present, with NPS park units in green. Class I areas have linkable access to ARIS information.
