WMS Service (Web Map Service) Nitrogen Dioxide Stations (NO2) – Hourly Limit Value (VLH)

The Map Web Service called Nitrogen Dioxide Stations (NO2) – Time Limit Value (VLH) allows the visualisation and consultation of the cartography containing the fixed air quality stations that have been used to carry out the assessment in accordance with Directive 2088/50/EC and RD 102/2011 on the improvement of air quality. The Hourly Limit Value for Nitrogen Dioxide is 200µg/m³ (no more than 18 exceedances). The URL of the WMS Service Evaluation Sulfur Dioxide (SO2) – Timeline Value (VLH) is: https://wms.mapama.gob.es/sig/EvaluacionAmbiental/CalidadAire/Estaciones_VLH_NO2/wms.aspx The reference systems offered by this service are: —For geographical coordinates: CRS: 84, EPSG:4230 (ED50), EPSG:4326 (WGS 84), EPSG:4258 (ETRS 89). —For U.T.M coordinates: EPSG:32628 (WGS 84/UTM zone 28N), EPSG:32629 (WGS 84/UTM zone 29N), EPSG:32630 (WGS 84/UTM zone 30N), EPSG:32631 (WGS 84/UTM zone 31N), EPSG:25828 (ETRS 89/UTM zone 28N), EPSG:25829 (ETRS 89/UTM zone 29N), EPSG:25830 (ETRS 89/UTM zone 30N), EPSG:25830 (ETRS 89/UTM zone 31N), EPSG:25830 (ED50/UTM zone 28N), EPSG:25830 (ED50/UTM zone 29N), EPSG:25830 (ED50/UTM zone 30N), EPSG:25830 (ED50/UTM zone 31N).名为二氧化氮站点（Nitrogen Dioxide Stations，NO2）– 小时限值（VLH）的网络地图服务（Web Map Service，WMS），可实现对依据《2088/50/EC指令》及《空气质量改善条例（RD 102/2011）》开展空气质量评估所采用的固定监测站点的地图数据进行可视化与查询。二氧化氮小时限值为200μg/m³（年超标次数不得超过18次）。 评估用二氧化硫（Sulfur Dioxide，SO2）– 小时限值（VLH）的WMS访问地址为：https://wms.mapama.gob.es/sig/EvaluacionAmbiental/CalidadAire/Estaciones_VLH_NO2/wms.aspx 该服务提供的坐标参考系统如下： ——地理坐标参考系：CRS:84、EPSG:4230（ED50）、EPSG:4326（WGS 84）、EPSG:4258（ETRS 89）。 ——UTM坐标参考系：EPSG:32628（WGS 84/UTM 28N带）、EPSG:32629（WGS 84/UTM 29N带）、EPSG:32630（WGS 84/UTM 30N带）、EPSG:32631（WGS 84/UTM 31N带）、EPSG:25828（ETRS 89/UTM 28N带）、EPSG:25829（ETRS 89/UTM 29N带）、EPSG:25830（ETRS 89/UTM 30N带）、EPSG:25830（ETRS 89/UTM 31N带）、EPSG:25830（ED50/UTM 28N带）、EPSG:25830（ED50/UTM 29N带）、EPSG:25830（ED50/UTM 30N带）、EPSG:25830（ED50/UTM 31N带）。
