IN: Integrating Nephelometer
Purpose of Participation
- Observation of the aerosol scattering coefficient at Rabben station.
Instrument description
The instrument IN is used for measurement of the scattering coefficient. The complex refractive index was estimated from simultaneous measurements with an IN, an OPC and a PSAP.
| Species | Aerosol |
| Method | Measure the light scattering from aerosol. |
| Quantity primary | Scattering coefficient |
| Quantity secondary | in case of spherical particles: Single scattering albedo/ refractive index (combined measurements with the OPC and the PSAP) |
| Spectrum | 530 nm |
| Altitude range | |
| Vertical resolution | |
| Temporal resolution | 1 minutes |
| Operation | Always |
| Precision | ± 10% |
| Data availability (during campaign) | Next day |
| Final data (after campaign) | Six months |
Specific remarks
- ground-based system
