In past winters, to measure snowfall, observers had to bring containers of snow inside houses every hour. After the snow turns into water, it is measured with a measuring cup, so the whole process can only be done manually. However, nowadays, with the continuous acceleration of meteorological modernization, weighing precipitation sensors have basically replaced manual observations. It can automati...
