Vaisala RS-90 sonde has dual H-polymer humicap switching sequentially between heating(=de-icing) and measuring cycles (1999-2004 at FMI). FN-sonde of Lindenberg Observatory, Germany, uses slightly modified Vaisala RS-90 and Lindenberg’s own calibration/calculation method 16.09.2018 Esko Kyrö, Finnish Meteorological Institute

Vaisala Radiosonde RS-92 (2005 –> at FMI) Vaisala Radiosonde RS-92 (2005 –> at FMI). Humicap-h Unit in the Sensorboom Is the Same As in RS-90. Main Developments in Temperature Sensor (Very Small Radiation Corr/fast), in Calibration and Computation Procedures of Humicap, and Correlating GPS Wind Finding.
