Abstract
The invention relates to a method and temperature sensor structure for compensating radiation error particularly in a radiosonde, rocket sonde or dropsonde. According to the method, each sonde carries at least one temperature sensor. According to the invention, the temperature measurement is carried out by means of two temperature sensors, both having low emissivities but different absorption coefficients for solar radiation.
