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

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
