The description of design principles of horizontal gauge is presented. Comparison is made for about 28000 events of pit, national and horizontal gauges for seven years at 30 stations. The power function correlation between the horizontal precipitation and the absolute difference of observed precipitation was confirmed and the correlation coefficient is 0.99. Using the horizontal gauge, correction can be carried out for the precipitation (include snowfall) observed at normal stations by adding parallel observation of horizontal precipitation. The adjusted accuracy is close to that of pit gauge; moreover, the method has the advantages of simple and easy to do, and is applicable to the operation use.
