MODIS/MCST Calibration Plan
ObjectiveProvide a comprehensive review and integration of all methodologies
used to calibrate the MODIS instruments
ApproachIntegrate calibration plans from all sources and for all phases of the mission:
pre-launch, in-orbit, and on-boardEventually, provide an on-going structure of the methodologies used
to obtain the results in the MODIS Calibration HandbookInclude references to supporting and more detailed publications
ContextProvide an executive summary of -methodologies
from both external peer reviewed articles on MODIS calibration andinternal NASA readiness review documents
ScheduleProvide up-dated versions at
MODIS Science Team Meetings, andEOS Calibration/Validation Panel Meetings

MODIS/MCST Texture Utility AlgorithmObjectives and Approach
Create un-resampled level-2 data productsfor the three MODIS spatial resolutions
namely, 250,500 and 1000 m
Three 16-Bit Texture ProductsDevelop spatial texture measure using 250m bands
Calculate geophysically based texture measures

Global Calibration Site Selection Procedure
ObjectiveLocate potential MODIS calibration targets on the Earth’s surface
that are radiometrically homogeneous on a scale of 3 by 3 Km.Approach
Initially use annual NDVI biweekly datasets of 1 Km AVHRR datain the continental United States in 1990to search for radiometrically homogeneous regionsusing the standard deviation of a traveling 3X3 pixel areaas a measure of heterogeneity.
ContextUse calibration sites within the MODIS imagery to provide for
1) every-pass calibration-potentialusing a modified “radiometric rectification” methodology,
2) aircraft under-flight calibration support, and3) occasional support of ground field calibration experiments
ScheduleInitial results for 1990 dataset from EDC (EROS Data Center)
were reported at the Calibration Working Group sessionof the April 13th MODIS Science Team Meeting
