Landscape
• 1000m elevation range
• Covers 7860 km2
• Gradient from temperate and
boreal forests
• Variety of management practices
– National Parks
In 1895 the Laurentian Wildlife Reserve was
created to provide fishing, hunting, and recreation
opportunities for the people. It covers 7860km2.
In 1981 Jacques-Cartier Park was created out of
the wildlife reserve as a 671 km² conservation
park. The Jacques-Cartier River drains an area of
2515 square kilometres, starting in and flowing for
nearly 160 kilometers
• Jacques Cartier
• Grands-Jardins
– Montmorency experimental forests
(Université Laval)
– Lumber management

More Facts
• Classified as boreal zone
– Abies balsamea (Balsam Fur), Picea mariana
(Black Spruce), Betula papyrifera (Paper Birch)
– 1000-1600mm/year precipitation (35% is snow)
– Mean annual temperature (0-2 oC)
– Growth season between 130-140 days
• Public land -> Public access to all sites

UAVSAR campaigns 2009/2010
• UAVSAR Campaign Objectives
– Assess the potential of L-band polarimetric radar
to measure vegetation 3D structure/biomass
– Assess the potential of L-band polarimetric repeat
pass inSAR to measure vegetation 3D
structure/biomass
• Quantify temporal decorrelation

PI: Simard,CoI’s: Dubayah and Hensley
Funded by the NASA Terrestrial Ecology Program
•Test Sites cover a wide range of forest types
–New Hampshire (Temperate)
–Maine (Temperate)
–Québec (Temperate and boreal)
–Sierra (Temperate with strong elevational gradient)
–La Selva (Tropical)

Data collection strategy
•
•
•
UAVSAR images covered transects of ~185km with ~20km
swath
Covered boreal and temperate forests
Large diversity of management practices:
–
sites are characterized by experimental forests, national parks
and managed forests (e.g. lumber)
•
UAVSAR flew 3 days over a period of about 10 days.
•

The Eco3D flight campaign consisted of 3 instruments developed at GSFC (DBSAR,
SIMPL and CAR) flying simultaneously on the P-3 aircraft out of the Wallops flight
facility:
• DBSAR is a digital beamforming L-band Synthetic Aperture Radar
• SIMPL is a multibeam, dual-wavelength, polarimetric photon counting lidar
• CAR is a multiangular and multispectral passive sensor
The campaign took place in August-September, 2011
