Abstract:An analysis is made of the differences between automatic and manual daily mean meteorological measurements(24 times per day and 4 times per day,respectively),and the t-test method is used to determine whether there is distinct difference between the means of two samples.The analysis of differences between 24-times-per-day and 4-times-per-day observations show that there is remarkable deference in relative humidity for about half stations,and there is remarkable deference in daily temperature,pressure and 2-...
Keywords:AWS (automatic weather station)  manual observation  national base station
