Download service (WCS) of chimere model hourly analysis of species concentration from validity time D-1 00 UTC to validity time D-1 23 UTC on Europe, at the surface. Format GRIB2.

The service allows to download in grid point chimere model analysis of air quality and of the atmospheric composition on Europe. Analyzed parameter : concentration of species at surface level. Unit : kg/m3. Analysis from step -24H to step -1H, i.e from validity time D-1 00 UTC to validity time D-1 23 UTC (D 00 UTC reference time), with a time step of 1 hour. D is the day of the reference time. Spatial resolution on a regular latitude x longitude grid of 0.1x0.1 degree. GRIB2 format. More information can be found in the technical guide available on the CAMS regional website in the documentation category.本服务支持下载欧洲区域格点化希梅尔（CHIMERE）模式空气质量与大气成分分析场数据。分析参数为地表大气成分物种浓度，单位为千克每立方米（kg/m³）。分析时效覆盖-24小时至-1小时，即对应参考时刻D日00时UTC的前一日（D-1日）00时UTC至23时UTC，时间步长为1小时，其中D为参考时刻所属日期。数据采用0.1°×0.1°的规则经纬度网格空间分辨率，格式为GRIB2。更多详细信息可查阅CAMS区域网站文档分类下的技术指南。
