Salt Lake Valley Methane

What the network is doing right now. The daily products elsewhere on this dashboard are rebuilt once a day and say nothing about an instrument that stopped an hour ago; this page reads the live files directly and refreshes itself every minute.

Every stream

TRAX position and TRAX methane are listed separately because they arrive on different schedules: the GPS lands within a minute or two, the calibrated methane several hours later.

Has it been running?

Minutes per day in each location, from the same classifier the archive uses. A day with no time on the line collected nothing, however healthy the instrument looked.

Instrument health

Cavity pressure is the one to watch. The analyzer is specified for 135 to 145 torr, shaded below; running under that means a restricted inlet, which smooths the record rather than biasing it.

What the quality flags say

Most samples carrying a flag is normal. Reference-gas and inlet-flush periods are flagged by design, and a flag only matters if it means the atmospheric measurement is unusable.
