Radiosonde and atmospheric measurement methods performed at high temperatures

摘要

The present invention relates to a method and a radiosonde (1). According to the method, at least the atmospheric temperature and the relative humidity are measured with a radiosonde (1). According to the invention, the humidity measurement is carried out continuously at high temperatures in order to make the measurement faster. Both the high temperature and the ambient temperature are measured simultaneously and the relative humidity is determined based on those values. The humidity sensing element is disposed on the planar substrate.
