Research Activities
- Arizona Regional Image Archive (ARIA)
ARIA is an interdisciplinary resource system for digital image and map
data for the Sonoran desert region, including the US Southwest and
northern Mexico. Its focus is climate variability and change. Located
at the University of Arizona.
- ASTER Instrument
Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is an imaging instrument that flies on the Terra
satellite. It will be used to obtain detailed maps of land surface
temperature, emissivity, reflectance and elevation. Its ability to
serve as a 'zoom' lens for other instruments will be particularly
important.
- BIGFOOT: Characterizing Land Cover, Leaf Area Index, FPAR, and NPP
Funded by NASA's Terrestrial Ecology Program to validate the MODLand
products. BIGFOOT has four field sites: a boreal forest, a tallgrass
prairie, a mixed deciduous-conifer forest, and a mixed corn and soybean
agricultural system. The sites have active science programs
concentrating on CO2, water vapor, and energy exchange over a
"footprint" of land. They will develop fine-grain surfaces of land
cover and other data to compare with MODLand products.
- Biosphere-Atmosphere Interactions
Investigates processes governing exchanges of energy, water, carbon and
trace gases between the terrestrial biosphere and the atmosphere, to
model changes in climate and the carbon cycle over the next 50-100
years as Earth responds to changes in atmospheric composition and land
use.
- CalPhotos Image Retrieval
CalPhotos is a system for content-based image retrieval. Users can
query for photographs based on their location or the objects they contain. Includes land,
air, and water images.
- Canada Center for Remote Sensing
CCRS research areas for the Center include agriculture, land use and
land cover; disaster and environmental monitoring; and forestry,
geology, hydrology and marine mapping. Includes details of satellites,
sensors, and CCRS ground stations and services.
- Climate Change and Remote Sensing
Research group at the Department of Geography at Boston University. The
group is currently active on Climate Change and Remote Sensing and is
monitoring the change in growth of vegetation globally. Links to Terra
satellite and Earth Observatory.
- Department of Meteorology at University of Maryland, College Park
Research links at this site point to their work in concert with NASA
and others in the following areas: climate, glaciology, weather and
atmosphere, oceanography, and remote sensing, among others.
- Earth Observing System (EOS)
EOS is the centerpiece of NASA study of the Earth. It consists of a
science component and a data system supporting a coordinated series of
polar-orbiting and low inclination satellites for long-term global
observations of the land surface, biosphere, solid Earth, atmosphere,
and oceans.
- Earth System Science Interdisciplinary Center
University of Maryland research and teaching activities in Earth
Systems Science: satellite remote sensing of land, atmosphere and
ocean; land surface and atmospheric modeling; dynamics of climate and
tropical oceans; atmospheric aerosols; volcanology; glaciology;
atmospheric chemistry; and biogeochemical cycling; and more.
- EOS Land Validation Core Sites
Status of Sunphotometer Deployment includes maps and descriptions of the sites and measurements.
- GiST Indexing Project
GIST studies the engineering and mathematics behind content-based
indexing for massive amounts of complex content. The basis of the
project is the Generalized Search Tree (GIST), a template indexing
structure for indexing remote sensing databases and others.
- Global Land Ice Measurements from Space
Project to monitor the world's glaciers, primarily using data from the
ASTER (Advanced Spaceborne Thermal Emission and reflection Radiometer)
instrument aboard the EOS Terra spacecraft.
- GSFC Ice Altimetry Home Page
The Oceans and Ice branch of the Laboratory for Hydrospheric Physics of
NASA/GSFC has processed satellite radar and aircraft laser altimetry
over the continental ice sheets and surrounding sea ice to calculate
surface elevations.
- Master Airborne Simulator
The MASTER airborne simulator supports ASTER and MODIS instrument teams
in algorithm development, calibration and validation. It collects land
data sets at a higher resolution than the spaceborne data sets, to
permit scaling studies and comparisons with in-situ measurements.
- MODIS Land Team Validation (MODLAND)
MODLAND uses several validation techniques to develop uncertainty
information on its products. Techniques include collection of and
comparison with field and aircraft data, and comparison with data and
products from other satellites.
- NASA Ames Research Center CASA Home Page
The principal aim of global ecosystem studies at NASA Ames Research
Center, Moffett Field, CA, is to better understand the controls on
biogenic trace gas fluxes and the ecosystem processes that regulate
these gases.
- NASA GSFC Code 614.4 Calibration Facility
Facility that maintains instruments and NIST-traceable calibrated
sources to calibrate, monitor, and assess the performance of
satellite-, aircraft-, and ground-based remote sensing instrumentation.
Their instruments, sources, and expertise are available to US
government agencies, the international remote sensing community, and
academic institutions.
- NIST Optical Technology Division
Source of national measurement standards and support services to
advance the use and application of optical technologies spanning the
ultraviolet through microwave spectral regions.
- Radar Interferometry Group
Radar interferometry creates detailed images of geological surfaces
using synthetic aperture radar-mapping satellites. This powerful
technique can reveal centimeter-sized changes in the Earth's crust due
to natural phenomena. Images include changes in glaciers, volcanoes,
earthquake areas, and atmospheric water content.
- SAFARI 2000 Test Sites
Maps showing EOS Land validation sites in Africa. Includes related data.
- Simulation - Seasonal-Interannual Climate Variability over Amazonia
Site with summary and reports from research on "Coupled High-Resolution
Ocean-Land-Atmosphere Simulation of Seasonal-Interannual Climate
Variability over Amazonia."
- South West Asia Project (SWAP)
Yale Center for Earth Observation's site for project to quantify and
monitor the processes shaping the landscapes of Southwest Asia.
