BOREAS -- Airborne Fluxes and Meteorology (AFM) Group

The BOREAS Information System

The Airborne Fluxes and Meteorology (AFM) Group

AFM Group Objectives

The overall objectives of this group, which include work with field measurements (aircraft, radar, lidar, profilers, soundings, mesonet) and models, are to:

Characterize by measurement and by model the evolution of the atmospheric boundary layer and the boundary layer fluxes of sensible heat, latent heat, momentum, and CO₂ over the two BOREAS study areas and over a transect across the boreal forest zone (from near Saskatoon to an area northeast of Thompson).
Study and document the processes that link such fluxes from the local scale of surface measurements to the regional scale represented by the forest ecozone, and from the time spans of BOREAS measurements to those of global climate change.

The BOREAS AFM Airforce

A List of BOREAS Research Aircraft is available with brief descriptions of their equipment. Note that the aircraft are divided into two groups; remote sensing (optical and microwave/gamma) and flux measurement.

BOREAS Field Campaigns 1994

Four aircraft were used to measure turbulent fluxes; sounding lidars and radars were also deployed. Ten mesometeorological stations and a dense array of upper air radiosounding stations operated over the region during 1994. The Global Telecommunications System was used to transmit data from this network to operational meteorological centers for assimilation. Several investigators, including some with strong links to these centers, are using mesoscale and global scale atmospheric models in their studies of surface-atmosphere interactions.
