Differences Between Manual Observation and Automatic Observation of Temperature in the Altay Weather Stations
摘要
Abstract
The temperature data from the CAWS600SE-H Automatic and manual weather station in Altay from January 2004 to December 2011, parallel observations difference was analyzed. The results show that: the difference was large between the two stations; there are daily, seasonal variation and for the minimum and maximum temperatures, the systematic errors of manual observation was 0.05~0.20 ℃ below the auto-observation with normal distribution characteristics. The temperatures at the right points of the observation hours, manual observation was earlier than the automatic observation, resulting in the systematic errors, the error was greater when rapid change of temperature occurred, while after revised with the time difference method, the absolute error was generally reduced by 0.1~0.2 ℃ and both variance reduction was 0.142. For January and October, 4 and 24 number of times in day average mode, the frequency of the magnitude above 1 ℃of the error change difference reached to 15%. Except in July, the average difference of four times was 0.1 ℃ less than that of 24 times, and in October less than 0.5 ℃ or more. The impact of the average value model on day values was the biggest reaching to 3.7 ℃ but less on the quarterly data reaching to only 0.4 ℃. Systematic bias of automatic observation equipment, precision of measuring devices, sensitivity and differences in observation time and the cause of human factors caused the impact of observational errors.关键词
