Research
Interests:
The Remote Sensing and GIS Laboratory at U of T led by J.
Chen currently has the major focus on the following research
objectives: (1) mapping local and regional (Canada-wide)
spatial distributions of carbon sources and sinks in terrestrial
ecosystems, and (2) studying the interactions between carbon
and water cycling processes. To achieve these objectives,
the laboratory has the following on-going research activities:
remote sensing image processing, canopy radiation modeling,
optical measurements of canopy structure, leaf pigments
measurements and retrieval from hyperspectral images, foliage
clumping estimation from multiple angle remote sensing,
LAI algorithm development and mapping, forest age mapping
from optical remote sensing, NPP model development and mapping,
NEP and NBP model development and mapping, soil carbon modeling
for forested upland and wetland, remote sensing-based land
surface scheme (i.e., all major energy and mass components),
vertical atmospheric CO2 diffusion modeling, and multiple-layer
canopy stable isotope modeling, coupling of an ecosystem
model with a global circulation model, pixel-based watershed
hydrological modeling, coupling a hydrological model with
carbon cycle modeling at watershed level, spatial scaling
of ET, NPP and NEP with consideration of topography, etc.
Many of these activities are carried out in collaboration
with Canada Centre for Remote Sensing, Meteorological Services
of Canada, York University, and other organizations.
