Data presented in Panta et al. 2025 "Unveiling single-particle composition, size, shape, and mixing state of freshly emitted Icelandic dust via electron microscopy analysis", Atmos. Chem. Phys.

The elemental composition, size, and shape of freshly emitted dust were analyzed using Scanning Electron Microscopy (SEM) coupled with Energy-Dispersive X-ray Spectrometry (EDX), as reported in Panta et al. (2025). The data were collected during an intensive field campaign conducted as part of the FRontiers in dust minerAloGical coMposition and its Effects upoN climaTe (FRAGMENT) project, and the Iceland as a model for high-latitude dust sources – a combined experimental and modeling approach for characterization of dust emission and transport processes (HiLDA) project. The campaign took place in Iceland’s most prolific dust source region—the Dyngjunsandur desert—during August and September 2021.本研究参照Panta等（2025）的研究成果，采用扫描电子显微镜（Scanning Electron Microscopy, SEM）结合能量色散X射线光谱仪（Energy-Dispersive X-ray Spectrometry, EDX），对新鲜排放粉尘的元素组成、粒径与形貌特征开展分析。数据采集自一项强化野外考察工作，该考察系「粉尘矿物学组成及其对气候的影响」（FRontiers in dust minerAloGical coMposition and its Effects upoN climaTe, FRAGMENT）项目，以及「以冰岛作为高纬度粉尘源区模型——粉尘排放与传输过程表征实验与模拟联合研究」（HiLDA）项目的组成部分。本次野外考察于2021年8月至9月间，在冰岛最主要的粉尘源区——丁居桑杜尔（Dyngjunsandur）沙漠开展。
