2 Biomass-Flux Working Group Original draft with my edits The Biomass-Flux working group seeks to integrate land-atmosphere carbon fluxes, biomass, and changes in biomass across CMS to improve estimation of all three. The working group will: (1) query and identify domains in space and time for which various relevant projects overlap; (2) identify and encourage projects to cross-compare flux and biomass products (3) track and summarize results and outcomes of comparisons. The ultimate goal would be to reconcile measurements of biomass and biomass change with process model biomass/fluxes and atmospheric CO2 variability across NASA CMS projects working group topic seems to be a specific, detailed subset within the scopes of the algorithm assessment/intercomparison, system framework, MRV, and atmospheric validation working groups

3 Biomass-Flux Working Group Relevant CMS Themes CMS Biomass: monitor, manage biomass for greenhouse gas emissions Products: Static Biomass estimates at local to global scales CMS Flux: monitor and diagnose greenhouse gas variability Products: -  Biomass, component fluxes (fire, deforestation, harvest) -bottom up process models (diagnostic and dynamic) -atmospheric inversions and data assimilation estimates of sources and sinks derived from atmospheric measurements -relationship between above ground biomass change and atmospheric CO 2 (end-to-end) -how do biomass measurements constrain flux estimations? -how do flux estimations constrain biomass measurements?

4 BM* ATMOSHERIC CO 2 * NPP* Detritus RH Fire* Mortality* Products O  C atm =- NPP*+ RH + Fire* + Prodout (Flux focus)  C BM = NPP*– Fire* – Mort* - Removals* (Biomass focus) Removals Not Local *potentially informed from Remote Sensing Data At steady state:   C BM = -  C atm But not over shorter periods of time and locally, also true for component fluxes

5 AGE (decades to centuries) Mortality Deforestation, Degradation Harvest & Fire Growth Enhancement Afforestation Biomass Net Flux + - Harvest (remove and emitted elsewhere later) Fire (emitted locally and immediately) +mortality (emitted slowly) Neutral over decades to centuries Long term atmospheric CO2 sinks long term atmospheric CO2 source Dynamics of Biomass and Flux

6 Relationship between Biomass change and Net Flux at local scales UMBS, Gough et al., 2008 Net Flux sink = 1.6 MgC/ha/yr  AGB = 2.2MgC/ha/yr HF, Urbanski et al., 2007 Net Flux sink= 2.5 MgC/ha/yr  AGB = 1.3 MgC/ha/yr

7 EXAMPLE of using biomass measurements to constrain flux models: Static Biomass estimates to constrain flux models: Biomass is a function of NPP, allocation, mortality, harvest, fuel loads. A weak constraint on modeled fluxes

8 Williams et al., 2012, 2014 Another EXAMPLE: Static Biomass + disturbance history to Parameterize flux models Landsat VCT

9 Strategy for linking Biomass products with Flux Products Working Group membership should include projects willing to contribute products that are useful for reconciling BM, fluxes, and atmospheric CO2 variability. Group would define products at useful resolutions, formats and establish working collaborations Issues to be resolved: Problem of scale: at what spatial resolutions can biomass change estimates be related to atmospheric CO2 variability? How to verify/validate modeled fluxes indirect model testing to support confidence in model predictions (local to global) direct measurement of fluxes (eddy covariance, tall towers for regional fluxes) net flux estimations using atmospheric CO2 observations and transport models (regional to global) Should scope be expanded to consider CH4, other biomass and detrital pools? NOTE OVERLAP with other Working Groups: Algorithm Assessment/Intercomparisons System Framework Atmospheric Validation MRV
