AL30 sessions

Preliminary means were 174 ng m⁻³ on Day 1 and 654 ng m⁻³ on Day 2. Day 2 was approximately 3.76 times Day 1. This demonstrates session variability but does not identify its cause.

The inventory records 25 samples, HUAY26_01–25, with a nominal maximum volume of 1.25 L. Atmospheric eBC and snow/ice rBC must be connected through transport and deposition windows rather than direct concentration equality.
