Abstract

A method and apparatus in connection with a hydrometeor measuring device. According to the method, the amount of precipitation is determined with the aid of the number and size of the hydrometeors. The determining of the size of the hydrometeors is altered as a function of the prevailing atmospheric pressure, in such a way that, the higher the atmospheric pressure, the larger a hydrometeor with the same speed will be estimated to be.
