Determining the Contribution of Emissions from Boreal Forest Fires to Interannual
Variations in Atmospheric CO at High Northern Latitudes
Abstract
This project is being
funded through NASA's NRA-99-OES-04: Investigations that Contribute to the NASA
Earth Science Enterprise's Modeling and Data Analysis Research.
Co-Investigators on this project include Nancy French of the Environmental
Research Institute of Michigan, Brian Stocks of the Canadian Forest Service,
and Slava Kharuk and Anatoly Sukhinin of the Sukachev Forest Institute,
Siberian Branch of the Russian Academy of Sciences, Krasnoyarsk, Russia.
Collaborators on this project include Susan Conard of the U.S. Forest Service
and James Randerson
of the California Institute of Technology. The overall goal of this project is
to use information derived from satellite observations available through NASA's
Earth Science Enterprise to reduce the uncertainties in the constraints on fire
carbon emissions estimates for the boreal forest. The hypothesis that we will
test in this interdisciplinary science investigation is that the interannual
variations in the fire regime in the boreal forest are responsible for a
significant portion of the interannual variations in the seasonal amplitude of
the atmospheric CO2 record at high northern latitudes. By
quantifying the biomass burning component of the seasonal amplitude, we can
begin to distinguish among different mechanisms, including changes in the
length of the growing season, the effects of interannual variability in snow
and ice cover, and the direct effects of temperature and soil moisture on
ecosystem carbon fluxes. The goals of this project will be achieved by using
satellite imagery to provide three important pieces of information: (1) we will
analyze the AVHRR data collected over Russia from 1978 to 1999 and combine this
information with fire boundaries produced by MODIS and fire records from North
America to produce a global boreal forest fire boundary map for the time
periods of 1978 to 2002; (2) we will further calibrate the areal extent of
fires in the boreal forest by using finer resolution Landsat imagery to
estimate total area in selected regions; and (3) we will use information
derived from Landsat imagery to estimate patterns of biomass burning/fire
severity in different boreal forest regions. This information will be used to
derive estimates of direct carbon release from fires in the boreal forest. The
output from this project will be spatial/temporal estimates of CO2
emissions, plus emissions of other carbon-based greenhouse gases (methane,
carbon monoxide). We will compare estimates of CO2 emissions from
fires to the record of atmospheric variations in CO2 concentrations
derived from surface flask data at high northern latitude stations to determine
how much the variation in the atmospheric record is due to emissions from fire.
We will also use outputs from the CASA model to compare the variations observed
from fires to those predicted for biological processes, such as photosynthesis,
plant respiration, and heterotrophic respiration.
Effects of Fire on Seasonal Patterns of Net Primary Production in Fire Disturbed Boreal Forests
Abstract
This project is being funded
through NASA's NRA-99-OES-10: RADARSAT-1/ADRO-2. Co-Investigators on this
project include Scott
Goetz and Steve Prince
of the Department of Geography, University of Maryland and Laura
Bourgeau-Chavez of Veridian-ERIM International.
The goal of this project is to investigate the effects of fire on patterns of net
primary productivity in the black spruce forest ecosytems of Alaska. It has
been hypothesized by some that recent warming has been responsible for
increases in net primary production (NPP) in the boreal forest region, but
these theories do not account for variations in NPP that result from
disturbance. The hypothesis for our study is that changes in forest cover as a
result of fire result in an increase in NPP, particularly if there is a shift
in ecosystem type from black spruce to deciduous forests. We will investigate
this hypothesis by studying a region of Alaska (the Upper Tanana River Valley)
where on-going field studies provide a rich source of data to validate an
existing NPP model) the GLO-PEM
model of the University of Maryland that uses satellite imagery from NOAA's
AVHRR system to provide model inputs. We will modify components of this model
to account for the effects that fires have on the surface characteristics
detected by the AVHRR sensor (changes in NDVI, surface brightness temperature,
and surface moisture characteristics). We will obtain AVHRR imagery for
selected time periods between 1997 and 2000 that match dates where NPP
measurements were or will be obtained using eddy covariance techniques (these
data are being collected as part of an ongoing NSF study). Particular attention
will be paid to calibrate the AVHRR-derived input parameters using
finer-spatial scale measurements obtained from imaging radars (soil moisture
characteristics) and Landsat TM/ETM data (NDVI, FPAR, albedo, surface
brightness temperature). These latter investigations will build upon existing
research programs being funded by NASA through a joint Alaska SAR Facility/IARC
grant and a NASA Global Change Fellowship. Once the NPP model has been
validated using the field observations, it will be applied to a large portion
of Alaska's boreal forest for the time period of 1990 to 1999 to assess the
regional significance of fire on the carbon balance. We will pay particular
attention to estimating how NPP varies in a series of large fires that occurred
in 1990 and 1991 as a function of time after recovery from fire. For more information, check out this PowerPoint presentation.
Monitoring Effects of Fire in Alaskan Boreal Forests
Project Description
This project is being
carried out as part of the Long Term Ecological Research Program at the Bonanza Creek Experimental Forest. Under
this project, we join scientists from throughout the U.S. in studying important
ecosystem processes in the boreal forest. Our particular research is focused on
two areas: (1) better quantifying the spatial patterns of fire severity and
consumption of organic soils in fires in the Alaskan boreal forest; and (2)
understanding how fires influence annual patterns of soil temperature,
moisture, CO2 emissions and the surface energy budget. Of particular
interest is a 1999 fire that took
place near Delta Junction, Alaska.
The Use of Satellite Fire Products and Models to Investigate the Effects of Fire on
the Global Carbon Cycle
Project Description
This project is being funded through NASA's NRA-99-OES-04: Investigations that Contribute to the NASA Earth
Science Enterprise's Modeling and Data Analysis Research. The Principal
Investigator for this project is James Randerson of the
California Institute of Technology. Our role in this investigation is to
provide inputs of greenhouse gas emissions from fires in the boreal forest
based on our own research project.
Co-Investigators include Sietse Los of NASA's Goddard Space Flight Institute.
Effects of the Development of the
Baikal-Amur Mainline Railroad on Patterns of Boreal Forest Cover and Carbon in
Southern Siberia
Project Description
This project was funded through NASA's Land Cover/Land Use Change Program. Collaborators on this
program include Hank Shugart of the University of Virginia and Kathleen Bergen
of the University of Michigan. The goals of the project were: (1) to develop
approaches to monitor patterns of disturbance associated with the building of
the railroad systems that transected southern Siberia: and (2) determine how,
when combined with natural disturbances from insects and fires, they are
controlling patterns of forest cover in this region, as well as carbon storage
in these forests.(PowerPoint

Environmental Working Group Boreal Forest Study
Project Description
Since 1993, Russian and U.S. scientists have carried out joint investigations as part of the U.S.-Russian
Joint Commission on Economic and Technological Cooperation. One of these
projects focused on evaluating the utility of using information derived from
national security satellites for monitoring key characteristics of forests found
in the high latitude regions of Russia and the U.S. The initial
studies determined that derived products from national security systems provided
a unique perspective on key processes in the boreal forest, particularly
monitoring severity of disturbance and forest recovery after disturbance.
Ongoing studies are focusing on using information derived from national
security systems to study critical aspects of the terrestrial carbon budget in
this biome.
