Experiment Set Details
Name: D3 Experiments
Time format and units: CIMS time is in number of seconds since Jan 1st, 1904 in UTC. NOx data is in M/D/Y Hr:Min:Sec format in local time.
Description:
CIMS and NOx data (if available) for measurements of D3 oxidation with conditions favoring different peroxy radical fates. Three radical precursors were used: HONO, H2O2, and Cl2.
