The Moon's time-dependent luminance was determined during the 9 February 1990 and 3 March 2007 total lunar eclipses by using calibrated, industry standard photometers. After the results were corrected to unit air mass and to standard distances for both Moon and Sun, an absolute calibration was accomplished by using the Sun's known luminance and a pre-eclipse lunar albedo of approximately 13.5%. The measured minimum level of brightness in the total phase of both eclipses was relatively high, namely -3.32 m(vis) and -1.7 m(vis), which hints at the absence of pronounced stratospheric aerosol. The light curves were modeled in such a way as to let the Moon move through an artificial Earth shadow composed of a multitude of disk and ring zones, containing a relative luminance data set from an atmospheric radiative transfer calculation.
利用经过校准的行业标准光度计，在1990年2月9日和2007年3月3日的月全食期间测定了月球随时间变化的亮度。在将结果校正到单位空气质量以及月球和太阳的标准距离后，通过使用太阳已知的亮度和月食前约13.5%的月球反照率完成了绝对校准。两次月食全食阶段测得的最低亮度水平相对较高，分别为-3.32星等（可见光）和-1.7星等（可见光），这表明平流层中没有明显的气溶胶。通过让月球穿过由多个圆盘和环形区域组成的人造地球阴影来模拟光变曲线，其中包含来自大气辐射传输计算的相对亮度数据集。
