Hamburger Luftmessnetz (HaLm)

The Hamburger Luftmessnetz (Halm) * operates 15 air quality monitoring stations * distinguishes between background, ozone and traffic measurement stations * continuously measures in accordance with EU directives and the Federal Immission Control Act The background measuring stations are used for general air monitoring. They cover the pollutant components sulphur dioxide (SO2), nitric oxide (NO), nitrogen dioxide (NO2) and suspended dust (fine particulate matter PM10: Particles less than 10 microns and particulate matter PM2.5: Particles less than 2.5 microns). One station also measures carbon monoxide (CO). In addition to ozone (O3), the ozone measuring stations also determine the NO2 and NO loads. At the traffic measuring stations, the pollutants NO, NO2 and particulate matter PM10 or particulate matter PM2,5 as well as partly benzene and CO are measured at the traffic measurement stations. The measurements are carried out continuously in accordance with EU directives and the Federal Emissions Control Act and fulfil the following tasks/purposes: * Measurements according to the EU directives for particulate matter PM10/PM2.5, sulphur dioxide (SO2), nitrogen dioxide (NO2), benzene, carbon monoxide (CO) and ozone (O3), as transposed in the 39th Ordinance on the Federal Emissions Control Act (39. BImSchV) * Ozone warning and information service * Information to the public * Provision of data for immission protection permits * Establishment of data time series to determine stress trends * General monitoring of air quality in accordance with the Fourth General Administrative Regulation on the Federal Immission Control Act After automatic and manual plausibility check, the measurement data is stored in a database and can be evaluated at the headquarters of the Hamburg air measurement network with various software tools. Current hourly averages are made available to the public via video text (Norddeutscher Rundfunk NDR page 678, Hamburg1 page 155) and Internet (https://luft.hamburg.de). In addition, the website contains summarised and historical data, characterisations of the measuring stations as well as further explanations of content.汉堡空气监测网络（Hamburger Luftmessnetz，简称Halm） * 运营15座空气质量监测站，划分为背景型、臭氧型与交通型三类监测站点 * 按照欧盟指令（EU directives）及《联邦排放控制法》（Federal Immission Control Act）开展持续监测 背景型监测站用于常规大气质量监测，覆盖的污染物组分包括二氧化硫（SO₂）、一氧化氮（NO）、二氧化氮（NO₂）与悬浮颗粒物（细颗粒物PM10：粒径小于10微米的颗粒物；细颗粒物PM2.5：粒径小于2.5微米的颗粒物）。其中1座站点还会监测一氧化碳（CO）。臭氧型监测站除臭氧（O₃）外，还可测定二氧化氮（NO₂）与一氧化氮（NO）的污染负荷。交通型监测站则会监测NO、NO₂、PM10或PM2.5颗粒物，部分站点还会同步监测苯及一氧化碳（CO）。 本网络的监测工作严格按照欧盟指令及《联邦排放控制法》持续开展，承担以下任务与用途： * 依据欧盟指令针对PM10/PM2.5颗粒物、二氧化硫（SO₂）、二氧化氮（NO₂）、苯、一氧化碳（CO）及臭氧（O₃）开展监测，相关要求已纳入《联邦排放控制法第39号条例》（39. BImSchV） * 臭氧预警与信息服务 * 面向公众提供环境信息 * 为排放管控许可审批提供数据支撑 * 建立数据时间序列以研判污染负荷变化趋势 * 依据《联邦排放控制法第四项通用行政条例》开展常规空气质量监测 监测数据经自动与人工合理性校验后，将存储至数据库，并可由汉堡空气监测网络总部借助各类软件工具开展分析评估。当前的小时均值数据会通过视频文字播报（北德意志广播公司（Norddeutscher Rundfunk，简称NDR）第678频道、汉堡1台第155频道）及官方网站（https://luft.hamburg.de）向公众公开。此外，该网站还提供汇总数据与历史数据、监测站概况说明及相关内容的详细解释。
