Approach
- higher-resolution airborne or satellite sensors,
and - data from ground-based studies at validation
core sites, flux towers, data from literature,
etc.
Data Sources
- EOS Land Validation Core Sites
- 32 sites stratified by six biomes
- Based on existing stations, projects, and
networks - FLUXNET, AERONET, BigFoot, LTER, etc. ,
- Long-term monitoring
- Jointly nominated by Instrument and Validation PIs
- In Situ Data
- Data needs and schedules
defined by working
with
MODLAND Validation scientists - Investigators are responsible for
processing,
documenting, QA, and providing access to their
data - Provide Mercury system for search and retrieval,
for both in situ and remote sensing data - Land Validation data will be archive at ORNL DAAC
- Also provide Regional and Global data sets for
modeling as part of ORNL DAAC mission
- Remote Sensing Data
- Landsat 5, ETM, IKONOS,
- ASTER, airborne sensors,
- subsetted over the core sites
- in situ Site Data
- Collected by various groups
- at core sites, available via Mercury
- Networks
- AERONET, FLUXNET, etc.
- Ancillary Site Data/GIS Layers
- - site variables
- - elevation
- - land cover
- - reference layers (e.g., political
- boundaries, airports, water
- bodies)
Historical data from literature
Oak Ridge National Laboratory is managed by
UT-Battelle, LLC, for the U.S. Dept. of
Energy under contract DE-AC05-00OR22725.
