Particulate mass (DP1.00101.001)

This product contains the quality-controlled, native sampling resolution data from NEON's particulate mass sampling protocol. Samples are collected by an automated assembly that pulls air through a quartz microfiber filter with a porosity of 10 micrometers, to collect PM10. Filters are weighed at high precision pre- and post-deployment to determine dust deposition mass. In addition to determining mass concentration of PM10, filters from the particulate mass analyzers will be archived in laboratory storage. Subsamples of the filters will be available to science community upon request to enable the assessment of chemical and nutrient inputs in the region.

本数据集包含经质量管控的原生采样分辨率数据，源自美国国家生态观测站网络（NEON）的颗粒物质量采样规程。采样由自动化采样装置完成，该装置将空气抽过孔径为10微米的石英微纤维滤膜，以采集PM10颗粒物。在部署前后，均会以高精度对滤膜进行称重，以计算粉尘沉降质量。除测定PM10的质量浓度外，颗粒物质量分析仪配套的滤膜还将被存档于实验室存储空间中。科研人员可通过申请获取该滤膜的子样本，以开展该区域化学物质与营养盐输入情况的评估研究。
