用于确定颗粒不对称性参数的便携式装置
Portable device to determine particle asymmetry parameter
摘要：
非对称性参数g的精确表征对于许多辐射传输和气候模式都是至关重要的。在这里，我们提出了我们的便携式光散射（PLS）设备，该设备是专为在现场，实时，和无接触测量的颗粒相函数的积分时间小于1秒。与PLS设备，我们的特点是含碳气溶胶，如从阿拉斯加泥炭阴燃产品，从煤油灯和非含碳气溶胶，如亚利桑那州的道路灰尘煤烟。我们发现这三种颗粒的g分别为0.664+/-0.002，0.506 +/-0.004和0.701+/-0.020。与商业浊度计相比，我们的PLS设备由于角截断而减少了g的误差。
英文摘要：
Accurate characterization of the asymmetry parameter g is of crucial importance for many radiative transfer and climate models. Here, we present our portable light scattering (PLS) device which is designed for in situ, real-time, and contact-free measurements of the particles phase function with an integration time less than 1 second. With the PLS device, we have characterized carbonaceous aerosols, such as smoldering products from Alaskan peat, soot from a kerosene lamp and non-carbonaceous aerosols such as Arizona Road Dust. We found the g to be 0.664+/-0.002, 0.506+/-0.004, and 0.701+/-0.020 for those three kinds of particles, respectively. Compare to commercial nephelometers, our PLS device has reduced error in g due to angular truncation.
