Ratified air quality - nitrogen dioxide

Datasets showing ratified nitrogen dioxide levels (NO2) at various locations around Leeds. The data is broken down into 15 minute averages. 

Please note
-----------

* The data is not necessarily collected for all dates/times/stations.
* Data collected within 6 months of today's date will be provisional and not verified as accurate.
* Data within the last calendar year will be published at hourly intervals and then once verified the 15 minute averages will be published.

* Annual nitrogen diffusion tube data is also available here: [https://datamillnorth.org/dataset/leeds-nitrogen-dioxide-diffusion-tube-network](/dataset/leeds-nitrogen-dioxide-diffusion-tube-network)
* Unratified data on the previously collected dataset is available here: [https://datamillnorth.org/dataset/air-quality-nitrogen-dioxide](/dataset/air-quality-nitrogen-dioxide). Please note, this dataset is now archived and will not be updated.

展示利兹市各地点批准的二氧化氮（NO2）浓度数据集。数据按15分钟平均值进行细分。

请注意

* 数据并非针对所有日期/时间/站点进行收集。
* 采集日期在今日起六个月内者，为临时数据，未经验证，可能存在误差。
* 过去一年内的数据将以每小时间隔发布，经核实后，将发布15分钟平均值。
