Platform: Ground Site

Aerodyne Research Inc

McCall, ID

Operated by Scott Herndon, Aerodyne Research Inc.

Observations and Sampling Location

Ground measurements during summer 2019 are based out of McCall. Instrumentation will be hosted at a remote property used seasonally for winter recreational activities. The focus at the ground site is to employ state-of-the-art collection techniques to speciate and quantify vapors and particulate matter associated with wild fire emissions and its subsequent atmospheric oxidation. These instruments typically have slow time resolution (≥ 15 minutes) which makes them inappropriate for the mobile payload. Both the NASA Langley Mobile Laboratory (LML) and the Aerodyne Mobile Laboratory (AML) will be parked and measuring nearby when not on sorties. Operating at the McCall "Activity Barn" site August 2019:

Key Research Goals

  1. Quantify biomass burning species in mixed-aged air and assess exposure in alpine-valley town (AML parked).
  2. Quantify biomass burning species in relatively fresh air. AML drives to smoke flooded valleys to investigate:
    • vertical structure
    • temporal character of flooding/ventilating
    • PAM-oxidation flow reactor measurement
    • assess acute exposure in alpine-valley town
