Comparison and Evaluation of Soil Moisture in Automatic and Artificial Observation Data and Construction of Humidity Model
摘要
Abstract
Based on the observation data of soil moisture of automatic observation and artificial synchronization in Juxian Meteorological Bureau from February to August in 2011,the comparison difference,difference probability and correlation coefficient were used to analyze and evaluate,and the humidity model was established by regression.The results showed that the maximum absolute error was 5.799%,the minimum absolute error was 2.025%,and the average absolute error of 0-100 cm was 3.306%,which was in accordance with the standards of China Meteorological Administration.But the error value of 30-40 cm was larger,indicating that the correction curve error by the manufacturer was too large,the absolute error of the observed data after correction was very small,the revised effect was ideal,through the comparative assessment.The model construction of relative humidity provides a guiding method for the practical application of automatic soil moisture observation data.关键词
