The 2026 campaign produced 48 samples coded QUEL2026_01–48, with a nominal maximum volume of 2.40 L. Field observations described visually clean, highly reflective and stratified snow; visual appearance cannot establish the absence of light-absorbing particles.

A context AL30 measurement of 222 ng m⁻³ is available. It is not a campaign mean, climatology or deposition rate. SP2 and ion products remain preliminary and require frozen units, blanks, replicates, detection limits, depth and traceability.
