  Total Column Ozon is a critical factor affecting the earths atmosphere,
especially in the Himalayan region. A comprehensive study of TCO trend analysis
and corresponding consequences in the Himalayan atmosphere needs to be
analyzed. We statistically examine TCO variability by analyzing the daily TCO
dataset of the last 15 years i.e.2005-2019 over the crucial region of the
Himalayan environment i.e. Uttarakhand, India. The outcomes of this study are
expected to be beneficial for future study of TCO over other crucial regions of
Himalayan territory.
