Air Quality Monitoring Station Data - Air Quality Station 4, Wharf Street, Sowerby Bridge

These data files are periodic (15 minutes) measurements of the concentration of nitrogen dioxide and particulate matter in the air for the monitoring station at Wharf Street, Sowerby Bridge. The units are measured in micrograms per cubic metre ( PM2.5 and PM10 are fine particulate matter).

Each file shows data for a whole year, the file uses the name R4 for the Air Quality Station 4. The data has been checked and calculations made on them to produce the final result.

Data for our other two stations in [Hebden Bridge](https://dataworks.calderdale.gov.uk/dataset/air-quality-monitoring-station-data---air-quality-station-3-market-street--hebden-bridge) and [Halifax](https://dataworks.calderdale.gov.uk/dataset/air-quality-monitoring-station-data----air-quality-station-2-salterhebble--halifax) can be found on separate datasets.

本数据集收录了位于索尔比桥码头街的空气质量监测站对空气中二氧化氮和颗粒物浓度的周期性（每15分钟一次）测量数据。浓度单位以每立方米微克（PM2.5和PM10为细颗粒物）计。每个文件展示了一整年的数据，其中文件名称采用R4标识空气质量站4。数据已经过检查并进行了计算，以生成最终结果。其他两个监测站（海布登桥[https://dataworks.calderdale.gov.uk/dataset/air-quality-monitoring-station-data---air-quality-station-3-market-street--hebden-bridge] 和哈利法克斯[https://dataworks.calderdale.gov.uk/dataset/air-quality-monitoring-station-data----air-quality-station-2-salterhebble--halifax]）的数据分别存储在独立的数据集中。详细的报告可在卡莱尔地区网站上通过[空气质量报告](https://www.calderdale.gov.uk/v2/businesses/pollution/air-quality/air-quality-reports)部分查阅。
