Weather Records for the Elora Research Station, Elora, Ontario [Canada]: Meteorological data 1999 to 2003

The University of Guelph, School of Environmental Sciences, Agricultural and Forest Meteorology Group, in cooperation with Environment Canada, maintains an automatic weather station at the Elora Research Station located a few kilometres south of Elora, Ontario. This station collects hourly climatic data including air temperature, relative humidity, wind direction and speed, solar radiation, net radiation, precipitation, and soil temperature. This data set includes climatic data collected from 1999 to September 30, 2003, and is presented as monthly data files broken down into four categories: hourly data, 0800 (maximum/minimum values for data collected from 1600 yesterday to 0800 today), 1600 (maximum/minimum values for data collected from 0800 today to 1600 today), and precipitation (at every minute of occurrence) data. Annual files are also available for hourly, 0800, and 1600 data. Supplement data collected by hand, including temperature, humidity and precipitation data, organized by year is also included. The weather station was fitted with an updated suite of instruments during August 2003 therefore a new set of meteorological parameters are being collected starting in September 2003. Data collected using the old system are included for September 2003 however some data was lost during the system conversion. The data for September 2003 to December 2003 collected using the new system are included in the study Weather Records for the Elora Research Station, Elora, Ontario [Canada]: Meteorological data 2003 to 2007.圭尔夫大学（University of Guelph）环境科学学院农业与森林气象学小组，与加拿大环境部（Environment Canada）合作，在安大略省埃洛拉以南数公里的埃洛拉研究站（Elora Research Station）部署了自动气象站。该站点采集逐小时气候观测数据，涵盖气温、相对湿度、风向与风速、太阳辐射、净辐射、降水量及土壤温度。本数据集包含1999年至2003年9月30日的气候资料，以月度数据文件形式呈现，分为四类：逐小时原始数据、0800时极值数据（采集时段为昨日1600时至今日0800时的观测值极值）、1600时极值数据（采集时段为今日0800时至今日1600时的观测值极值），以及分钟级降水事件数据。此外还提供逐小时、0800时及1600时数据的年度汇总文件。数据集同时附带按年份整理的人工观测补充数据，内容包含气温、湿度与降水量资料。该气象站于2003年8月完成观测仪器套件升级，自2003年9月起启用新的气象参数采集体系。2003年9月的观测数据仍包含旧系统采集的记录，但系统转换期间存在部分数据丢失。2003年9月至12月的新系统采集数据，已收录于研究文献《安大略省埃洛拉市埃洛拉研究站气象记录：2003至2007年气象数据》（Weather Records for the Elora Research Station, Elora, Ontario [Canada]: Meteorological data 2003 to 2007）中。
