基于两种数据传输途径的国家级地面自动站逐小时数据差异分析
Differences analysis of historical hourly meteorological data from national basic automatic weather stations due to use of two types of transportation data format
摘要
Abstract
The hourly data of 6 routine meteorological elements at 2400 national automatic weather stations from 2006 to 2009 were compared,and the data were obtained by A files and Z files (two types of data transport meth-ods).The results indicate that the hourly 2 min and 10 min wind data from two methods are significantly different because of the different artificial decisions for the wind direction when the wind speed is zero,while the other ele-ments from the two methods have relatively small difference.For the different data in two methods,the rates of temperature,air pressure,relative humidity,precipitation,2 min and 10 min winds within the instrumental error ran-ges are 23.27%,5.4%,23.19%,65.42%,12.93% and 14.16%,respectively.关键词
