Air Quality Monitoring - 2015

Annual hourly air quality and meteorological data by monitoring site for the 2015 calendar year. For more information on air quality, including live air data, please visit [environment.des.qld.gov.au/air](https://environment.des.qld.gov.au/air). \r\n \r\n**Data resolution:** One-hour average values (one-hour sum for rainfall) \r\n**Data row timestamp:** Start of averaging period \r\n**Missing data/not monitored:** Blank cell \r\n**Calm conditions:** No hourly average wind direction is reported when the hourly average wind speed is zero \r\n**Barometric pressure:** Values are at monitoring station elevation, not corrected to mean sea level \r\n**Daily zero/span response check:** Automated instrument zero/span response checks are conducted daily between midnight and 1am at Queensland Government sites (can differ at industry sites). Where this takes place an ambient hourly value cannot be reported. \r\n**Sampling height:** Four metres above ground (unless otherwise indicated) \r\n\r\n**PLEASE NOTE:** The Auckland Point 2015 air quality monitoring site data was updated on 23/04/2018 due to the wind direction sensor being misaligned and the reported wind direction values have now been corrected.

本数据集涵盖2015日历年各监测站点的逐小时空气质量与气象数据。如需获取更多空气质量相关信息（含实时空气质量数据），请访问[environment.des.qld.gov.au/air](https://environment.des.qld.gov.au/air)。

**数据分辨率**：采用小时平均数值（降雨量指标为小时累计总量）
**数据行时间戳**：对应平均计算时段的起始时刻
**缺失数据/未监测项**：以空白单元格标注
**静风状态**：当小时平均风速为0时，不报告小时平均风向
**气压**：数值为监测站所在地海拔处的实测值，未校正至海平面平均气压
**每日零点/跨度校验**：昆士兰州政府所属监测站点会于每日午夜至凌晨1时自动完成仪器零点与跨度校验（工业站点的校验时段可能存在差异）。校验期间将无法上报环境小时均值
**采样高度**：距地面4米（另有明确说明的除外）

**请注意**：奥克兰角2015年空气质量监测站点的数据集已于2018年4月23日完成更新，此前因风向传感器校准偏差导致的风向报告值现已修正。
