Abstract：Abstract: Automatic weather station elements of each sensor with the passage of time and changes in the environment, the measurement error will shift. To ensure that the various elements of observation data is accurate, reliable and comparable, regularly carry out automatic weather station of all elements of the verification and calibration is very important. Through the test the various elements of the system error is controlled within the allowable range, and the test results of uncertainty analysis, is to study the results credible degree important steps. On the basis of automatic weather station verification regulation requirements, and according to the testing data, automatic weather station and humidity sensor calibration uncertainty analysis on the verification, automatic weather station credibility evaluation has a guiding significance.
