The Doppler SODAR system PCS.2000 can be extended to a RASS system by using a CW radar transmitter and radar receiver units to derive vertical profiles of temperature and temperature gradient or height and strength of inversion layers simultaneously with the SODAR measurement. The RASS is completely integrated in the SODAR operation using the same processing unit running WINDOWS operating system.

Depending on national frequency regulations various radar units are offered (915, 1274 or 1290 MHz). For long range measurements up to heights of 1000 m, a 482 MHz version is available.
