PONEX - Experimental Design

Hangar Ground-based Site:

ECCC upper air site conducts 2x daily radiosonde launches & surface met obs:

Additional sonde launches during research flights

ECCC instrument suite for 24/7 automated obs provide:

Cal/val of Convair instruments
Fill gaps in observing capabilities (e.g., water vapour profiling)
Boundary layer & thermodynamic profiling observations
Surface meteorology and hydrometeor classification

University instruments:

AERI would complement FIRR-2, WV, trace gas profiling
UQAM Doppler lidar (winds, aerosols) at Trail Valley?
Additional instruments TBD

Trail Valley Creek site located North of Inuvik:

Suite of precipitation, meteorological, and radiation instruments (in-situ and remote sensing)
