outline
OUTLINE
  • Background and realities
  • MODIS-land contribution
  • MODIS-land participation in mid-continent intensive campaign(s)
  • Conclusions
background
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.
realities
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
modis land contribution
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
value added services
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

key products still needed
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
conclusions
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
