Carbon Cycle Field Campaigns in the Decadal
Survey Era
  • Forrest G. Hall, NASA/JCET/UMBC

  • GLORY 11/2010
  • AQUARIUS 12/2010
  • NPP 9/2011
  • LDCM 12/2012
  • OCO-2 2/2013
  • GPM CORE 7/2013 WITH JAXA
  • SAGE-III on ISS (11/2013)

NASA TERRESTRIAL ECOLOGY (TE) PROGRAM NEXT FIELD
CAMPAIGN
  • To date, no national or international program has
    proposed/developed an idea for a next major TE
    field campaign
  • In ROSES-2009, TE solicited for scoping studies
    for a major field campaign or related large
    project and 2 studies were selected and funded
    for 12 month scoping studies
  • Challenges and Opportunities in Remote Sensing of
    Global Savannas A Scoping Study for a New TE
    Field Campaign  (Hanan)
  • Vulnerability and Resiliency of Arctic and
    Sub-Arctic Landscapes (VuRSAL) - The Role of
    Interactions between Climate, Permafrost,
    Hydrology, and Disturbance in Driving Ecosystem
    Processes  (Kasischke)
  • Other ideas will be entertained there is no
    commitment to conduct one or the other or both.

CANNOT CLOSE THE GLOBAL CARBON BUDGET
Climate
Ecosystems
5
WE CANNOT CLOSE THE CARBON BUDGET AT ANY SCALE!
6
NACP SYNTHESIS
  • Continental flux estimates do not yet converge
  • Range of GPP estimates is surprisingly large
  • More controlled comparison of models is needed.

7
Need improved capability to close carbon budgets
at all scales.
  • MEASUREMENTS
  • Tower scale Getting close, but not quite there
  • Regional Scale Sufficiently dense and accurate
    GHG concentration measurements.
  • Limited biomass measurements. Lidar capability,
    but no space platforms. AC very expensive and
    impractical in some countries.
  • Canopy chemistry measurements related to
    photosynthetic rate, GPP.
  • Got Par, Fapar
  • Missing light use efficiency.
  • See algorithm section.
  • Oceans Improved capability for
    organic/inorganic flux/stocks

8
Need improved capability to close carbon budgets
at all scales.
  • MODELS PROCESSES
  • Some bottom-up models get it But which ones?
  • Model validation/selection an issue (MsTMIP)
  • Mapping model inputs at regional to global scales
  • Soils, soil moisture, freeze/thaw
  • Precipitation
  • Light Use Efficiency.
  • Heterotrophic respiration
  • Methane
  • Permafrost
  • Top Down (Inversion models).
  • Mesoscale transport models.
  • Mesoscale models can simulate atmospheric
    transport at high resolutions
  • sensitive to the specific convection schemes
  • boundary layer parameterizations
  •  Ecosystem Dynamics Models (diagnostic,
    prognostic)
  • Development, validation, couple with SVATs
  • Need structure inputs at regional to global
    scales

9
Need improved capability to close carbon budgets
at all scales.
  • ALGORITHMS
  • MODIS land team has provided first global, maps
    of some biophysical parameters needed for carbon
    flux models.
  • Vegetation fraction, Fpar
  • But no LUE yet Algorithms available
  • Lidar algorithms available for 3-d structure,
    biomass
  • But sampling only
  • Need fusion with Quad-pol Radar for contiguous
    mapping
  • Quad-Pol Radar algorithms are empirical only
  • L-band limited to lower third of biomass range
    (lt100Mg/ha)
  • P-band saturates at higher levels, but no space
    capablity
  • InSAR algorithms
  • In development, more testing needed.
  • No space capability yet

Carbon Cycle Data in the DECADAL SURVEY ERA
  • A rich array of multidisciplinary data
  • Many types
  • Many formats
  • Many scales
  • All essential to closing the carbon budget,
    understanding the implications for climate
    change, impact assessments etc.
  • How to make it more accessible?

17
WHAT TO DO WITH CARBON CYCLE FIELD CAMPAIGN DATA?
  • GOOGLIZE PI DATA
  • INTEGRATE WITH EXISTING DAACS
  • TAKE ADVANTAGE OF EXISTING ESDRS
  • TAKE ADVANTANCE OF OTHER FIELD DATA
  • INTERNATIONAL DATA SHARING ARRANGEMENTS
  • REFORMAT DOCUMENT TO A COMMON STANDARD
  • REGIONAL, NATIONAL
  • INTERNATIONAL?
  • ADD MANAGEMENT AND COORDINATION OF CARBON CYCLE
    CAMPAIGNS

18
EFFORT WILL BENEFIT FROM COORDINATED,
INTERNATIONAL, INTERDISCIPLINARY REGIONAL-SCALE
FIELD CAMPAIGNS AND READILY ACCESSIBLE
DATA WITH COMMON FORMATS, UNITS QUALITY CHECKED
