Maps of modeled concentration of Nitrogen and Sulfur components and Nitrogen deposition in the W Iberian Peninsula
收藏资源简介：
Concentration and deposition maps resulting from atmospheric chemical transport modeling, using FRAME (Fine Resolution Atmospheric Multi-pollutant Exchange, version number 9-15-0) for a domain including the western Iberian Peninsula, for 2015. Maps are provided at 5 km×5 km resolution in GeoTiff format relative to the local Portuguese datum Lisboa Hayford Gauss IGeoE (https://epsg.io/102164), and include: Mean air concentration of nitrogen oxides (NOx) in ug/m3; Mean air concentration of ammonia (NH3) in ug/m3; Mean concentration in the precipitation of ammonium (NH4+) in mg N/L; Mean concentration in the precipitation of nitrate (NO3-) in mg N/L; Mean concentration in the precipitation of sulfate, excluding the contribution from sea salt (xSO4-2), in mg S/L; Total Nitrogen deposition in kg N/ha.year. Modeling results were evaluated using measurements within the domain and deemed fit for purpose according to acceptance criteria by Hanna & Chang (2012), based on a set of statistical measures of evaluation proposed by Chang & Hanna (2004, 2005). This work was developed under project NitroPortugal (European Union's Horizon 2020 research and innovation programme under grant agreement No 692331). It was partly supported by the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCAPE programme delivering National Capability.

本数据集为采用FRAME（精细分辨率大气多污染物交换模型，Fine Resolution Atmospheric Multi-pollutant Exchange，版本号9-15-0）开展大气化学传输模拟所得到的浓度与沉降分布图，模拟区域涵盖伊比利亚半岛西部，时间范围为2015年。 数据以5 km×5 km分辨率的GeoTiff格式提供，采用葡萄牙本地基准面Lisboa Hayford Gauss IGeoE（https://epsg.io/102164）坐标系，包含以下要素： 1. 氮氧化物（NOx）的大气平均浓度，单位为μg/m³； 2. 氨（NH3）的大气平均浓度，单位为μg/m³； 3. 降水中铵根离子（NH4+）的平均浓度，单位为mg N/L； 4. 降水中硝酸根离子（NO3-）的平均浓度，单位为mg N/L； 5. 降水中硫酸盐（剔除海盐贡献的xSO4-2）的平均浓度，单位为mg S/L； 6. 总氮沉降量，单位为kg N/ha·year。 本模拟结果已通过研究区域内的实测数据进行验证，并依据Chang与Hanna（2004、2005）提出的系列统计评估指标，符合Hanna & Chang（2012）设定的模型适用性验收标准。 本研究依托NitroPortugal项目开展（该项目获欧盟地平线2020研究与创新计划资助，资助协议编号692331），同时得到英国自然环境研究委员会项目NE/R016429/1的部分支持，该项目作为UK-SCAPE计划的一部分，旨在提供国家研究能力支撑。Pedro Pinho感谢EC（H2020 BiodivERsA3 2015104 "BioVeins"）提供的资金资助。 ## 参考文献 1.
