Dr. Christopher Potter is currently a NASA Senior Research Scientist in the Ecosystem Science and
Technology Branch at Ames Research Center. He holds a Ph.D. and a Master's degree in forest ecology
from Emory University. He came to NASA in 1990 as a National Research Council (NRC) Associate. He and
his colleagues were awarded NASA's Public Service Medal for development of the first computer model
for global ecosystem exchange of all major biogenic trace gases with the atmosphere. Potter has been a
NASA Science Team Member on the Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA-ECO I and
II), EOS Interdisciplinary Science (EOS-IDS) , Intelligent Data Understanding , NASA's Astrobiology
Institute, the Boreal Ecosystem-Atmosphere Study (BOREAS), and Land Surface Hydrology. He is the
author of over 50 peer-reviewed journal articles and book chapters.
In 2007, Potter was selected as a NASA Ames Associate Fellow in recognition of exceptional scientific research achievement.

Steven A. Klooster is a Senior Research Scientist with California State University - Monterey Bay
(CSUMB) at the NASA-Ames Research Center (ARC) in the Earth Systems Science Division. He holds a
Master of Science in Engineering and Environmental Studies from the University of Wisconsin - Madison,
WI.
He designs and develops and implements global modeling software for studies of greenhouse trace gas
fluxes to study climatic change. This is accomplished by coupling a raster/GIS based simulation
modeling system that is compatible with remote sensing satellite data bases, scientific visualization
tools and geographic information system analysis techniques (GIS). He has ported this model to several
parallel computer systems.
He is currently co-developing with the University of Minnesota a set of scalable geo-spatial data
mining techniques by the innovative use of Knowledge Discovery and Datamining (KDD) techniques
uniquely applied to large geo-spatial scientific datasets. This uses methods to reveal or detect
anonomolies, relationships or interactions of multiple data inputs derived from advanced satellite
data products, climate variables and our NASA-CASA global biospheric model outputs.
As a past member of the Nimbus Science Team he implemented and validated the "Gordon method"
atmospheric correction algorithms developed for the Nimbus Ocean Color Research Program (CZCS). This
also included scan angle and sun angle dependence for each pixel. This and bio-optical algorithms were
tested and validated over Monterey Bay in Case-II waters.
The Gordon CZCS atmospheric and bio-optical algorithms were also extended using a longer infrared
reference channel included in the AOCI (Airborne Ocean Color Instrument, a SeaWiFS/SeaStar prototype).
This was for studies in Case-II studies and a near real time fisheries research project in the Gulf of
Mexico. This required systems design for data flow and real time processing. Chlorophyll concentration
and correlated phyto-pigments were determined for this in near coastal waters. Inertial navigation
data and the multispectral (AOCI) scanner imagery were merged into a geo-referenced database and
transmitted to the user.
While he worked as a hydrologist for the U.S. Geological Survey he devised a method to input
classified Landsat data into a regional ground water withdrawal model.
He has authored or co-authored over 40 papers on global modeling of trace gas fluxes or research
and applications related to ocean color, bio-optical oceanography and remote sensing related science.
