The atmosphere currently adds up. Does it have the right ingredients?
These are rounded dry-air proportions by volume; water vapor varies. NOAA: atmosphere · RSC: nitrogen.

We expect a substantial offer. Low bids will not be considered or answered.
A serious offer should take up more than the tiny 1% slice; the calculator is not accepting “mostly zeros” as a garnish.
