  1. MODIS contribution to NACP MODIS Land break-out Session March 24, 2005 Jeff Morisette1jeff.morisette@nasa.gov Bill Emanuel2 1 NASA Goddard2 NASA HQ

  2. OUTLINE • Background and realities • MODIS-land contribution • MODIS-land participation in mid-continent intensive campaign(s) • Conclusions

  3. Background • Several MODIS-land team members and associates are involved with NACP in some way • Specific projects • Science steering group • Inter-agency working group • NACP will rectify “top-down” and “bottom-up” approaches to derive continental carbon budgets. • “TD w/out BU is unexplained” • “BU w/out TD is unvalidated” (Dave Schimel) • MODIS-land data contribute significant input for BU modeling as well as for TD analyses.

  4. Realities • Little specific funding within the MODIS science team for NACP • No specific funding for an NACP data system • Wide range of remote sensing/MODIS experience among the NACP funded investigators

  5. MODIS-land contribution • Nearly all currently available MODIS land products provide information useful to carbon studies • Some value-added distribution could help integrate the currently available products into NACP efforts • Several key products are not currently available but could potentially be derived from MODIS data

  6. Value-added services • Mosaics for intensive study areas • Reprojecting • Reformation • Unpacking and filtering QA bits • Subsetting specific data layers LP DAAC and ORNL have tools and the capability, but limited resources Could be a test case for the LADS system

  7. Key products still needed • Improved agricultural maps • Crop type • C3/C4 continuous fields map • Wetlands map • Urban areas • Disturbance map (30+ year scale) • Forest stand age • Fire emissions • 250m LAI/fPAR/NPP products

  8. Previous BigfootPenn State/Davis study area Penn State/Warner study area USDA study area MODIS validation opportunities with mid-continent intensive SMEX05 experimental area

  9. Conclusions • Participation in the mid-west intensive field campaigns as a validation activity seems feasible • Value-added products could make a big impact but will require juggling limited resources • Some interesting new products are needed but not currently funded
