About this document
Global Extinction and Atmospheric Change by Majid Yousefi is a document available to read on EtoBox.
The document discusses the impact of long-term atmospheric changes on photometry using archival data from the Gemini North and South telescopes. It identifies a trend of worsening atmospheric attenuation, approximately 2 mmag per decade, and highlights a significant extinction event in 2009. The findings suggest that climate change is affecting astronomical observations, necessitating careful calibration of historical data and future surveys.
