评估：本手稿描述了使用涡流相关技术测量松林表面累积模式气溶胶（尺寸范围 0.25 <直径<1 μm）的干沉积速度的实验工作。气溶胶的数量通量是在短时间内测量为颗粒尺寸的函数。然后将它们用于计算尺寸相关的沉积速度。然后产生日平均沉积速度。还检查了沉积速度作为表面层湍流传输速率、摩擦速度的函数。虽然方法和结果并不是特别新颖，但它们确实建立在社区以前的经验的基础上，以最大限度地减少由于许多混淆问题而导致的不确定性
Evaluation: This manuscript describes experimental work to measure the dry deposition velocities of accumulation mode aerosols (in the size range 0.25 <diameter<1 μm) to a pine forest surface using an eddy correlation technique. Number fluxes of aerosols were measured as a function of particle size over a short period. These were then used to compute the size dependent deposition velocities. Diurnal averaged deposition velocities are then produced. Deposition velocities were also examined as a function of surface layer turbulent transport velocity rates, friction speed. Whilst the approach and the results are not particularly novel they do build on previous experiences in the community to minimize uncertainties due to a number of confounding issues
