论文摘要
在光度法中寻找长期大气变化的效果，使用双子座的北和南单双观光谱仪（GMOS-N和GMOS-S）档案数据。从2003年开始，将整个GMOS成像数据库与全天空的Gaia对象目录进行了比较，得出了〜10^6 Sloan r'-Filter样品，结束于2021年。这些样品与报告的天空和气象条件结合在一起，与大气的简单模型以及大气层以及模拟的云与模拟的通过模拟的遍布。在2009年，人们看到了一个异常灭绝的事件，每十年的趋势（在两个地点相似）也是如此。这与六十年来可以追溯到六十年的太阳能传播记录，气溶胶密度测量值以及全球空气温度的每十年升高0.2摄氏度c，这对校准历史数据集或未来的调查具有影响。
Effects of long-term atmospheric change were looked for in photometry employing the Gemini North and South twin Multi-Object Spectrograph (GMOS-N and GMOS-S) archival data. The whole GMOS imaging database, beginning from 2003, was compared against the all-sky Gaia object catalog, yielding ~10^6 Sloan r'-filter samples, ending in 2021. These were combined with reported sky and meteorological conditions, versus a simple model of the atmosphere plus cloud together with simulated throughputs. One exceptionally extincted episode in 2009 is seen, as is a trend (similar at both sites) of about 2 mmag worsening attenuation per decade. This is consistent with solar-radiance transmissivity records going back over six decades, aerosol density measurements, and more than 0.2 deg C per decade rise in global air temperature, which has implications for calibration of historic datasets or future surveys.
