Spectra of the real and imaginary parts of the refractive index m = n ' - in from 2.5 microm to 40 microm of ammonium sulfate, Sahara dust (as collected at Barbados), volcanic dust (pumice), and dust from a coalfired power plant are presented. With a peak absorption index n = 1.0 at 10 microm Sahara dust turns out to be the strongest absorber in the atmospheric window. The dispersion of n' is also very pronounced near 9 microm and 20 microm. Volcanic and coal-fire dust also absorb in the window region stronger than most of our earlier-investigated more normal aerosol fractions. The data for ammonium sulfate are compared with Remsberg's measurements on an aqueous solution.
给出了硫酸铵、撒哈拉沙漠尘埃（在巴巴多斯收集）、火山尘埃（浮石）以及燃煤电厂尘埃在2.5微米至40微米范围内折射率m = n' - in的实部和虚部的光谱。在10微米处峰值吸收指数n = 1.0，结果表明撒哈拉沙漠尘埃是大气窗口中最强的吸收体。n'的色散在9微米和20微米附近也非常明显。火山尘埃和燃煤尘埃在窗口区域的吸收也比我们之前研究的大多数更常见的气溶胶组分更强。将硫酸铵的数据与雷姆斯伯格对水溶液的测量结果进行了比较。
