The Ozone and Atmosphere in Vedas

The following are of Rigveda, 6th anuvaka,24 th hymn and 6,7 verses
नहि ते कषत्रं न सहो न मन्युं वयश्चनामी पतयन्त आपुः
नेमा आपो अनिमिषं चरन्तीर्न ये वातस्य परमिनन्त्यभ्वम

अबुध्ने राजा वरुणो वनस्योर्ध्वं सतूपं ददते पूतदक्षः
नीचीना सथुरुपरि बुध्न एषामस्मे अन्तर्निहिताःकेतवः सयुः
Meaning:
"Oh Varuna you are very known for your strengthness.Neither of birds and ever flowing water can reach you .Varuna are the king.He is in space which has no base.There He wears a luminous queen.His rays are passing from upper space to earth.The origin of those rays is in space only.Thatswhy our lives are survived."

If we think deep about these verses we can easily know that here Atmosphere is denoted as Varuna and the ozone layer is denoted as the luminous queen.If you see the last line of the second verse we know that" rays are passing to the earth and our lives are being survived".
The space originated rays are purified before reaching the earth.otherwise we cannot live.
