OTT Parsivel
| Laser optical Disdrometer |
| Description
|
|
|
Parsivel is a modern laser-based optical system for the complete and reliable measurement of all kinds of precipitation. The precipitation particles are differentiated and classified as drizzle, rain, sleet, hail, snow or mixed precipitation. For the precipitation measurements a special sensor head was developed. It measures precipitation optically one meter above the earth's surface (other heights are
available on request). The data determined thereby are processed and stored by a fast digital signal processor. The primarily determined data are the size and the velocity of each individual precipitation particle, from which the size spectrum, the amount of precipitation, the equivalent radar reflectivity, the visibility and the kinetic precipitation energy as well as the kind of precipitation are derived. The results can be transferred to a data logger or to a PC via serial interface. |
