NCore
NCore is a multi-pollutant network that integrates several advanced measurement systems for particles, pollutant gases and meteorology. NCore parameters are outlined below.
Features
| Parameter | Comments |
| PM2.5 speciation | Organic and elemental carbon, major ions and trace metals (24 hour average; every 3rd day); IMPROVE or CSN |
| PM2.5 FRM mass | 24 hr. average at least every 3rd day |
| continuous PM2.5 mass | 1 hour reporting interval; FEM or pre-FEM monitors |
| PM(10-2.5) mass | Filter-based or continuous |
| ozone (O3) | all gases through continuous monitors |
| carbon monoxide (CO) | capable of trace levels (low ppm and below) where needed |
| sulfur dioxide (SO2) | capable of trace levels (low ppb and below) where needed |
| nitrogen oxide (NO) | capable of trace levels (low ppb and below) where needed |
| total reactive nitrogen (NOy) | capable of trace levels (low ppb and below) where needed |
| surface meteorology | wind speed and direction (reported as “Resultant”), temperature, RH |
