PSP PRECISION SPECTRAL PYRANOMETER
Purpose of Participation
- Quantification of variability spectral solar radiation at the earth's surface in the Arctic due to variability in aerosols and cloudiness
- Contribution to analysis of closure between observed and calculated solar radiation fluxes
Instrument description
In this experiment a set of three Precision Spectral Pyranometers equipped with Schott filters measures global sun and sky radiation in the following spectral ranges 295-2800 nm (filter WG295), 395-2800 nm (filter GG395), and 695-2800 nm (filter RG8). The PSP comprises a circular multi-junction Eppley termopile. Its receiver is coated with Parsons' black lacquer (nonwavelength-selective absorption). The sensors convert the incident radiation into a voltage.
