  1. CARBON FLUXES OVER TEMPERATE ASIA N K INDIRA, PS SWATHI, PETER RAYNER, MICHEL RAMONET AND VINOD K GAUR

  2. and temperature ANSWERS SOUGHT: • How would future climate trends evolve in response to specified carbon emissions over a given period ? • How are we faring in achieving desired goals assuming some agreed regulatory measures in place ?

  3. C(X*,t*)=F(Xj,tj) * G(X*,X,t*,t) C(X*,t*)=Fn(Xj,tj)[δj*] C(X*,t*)

  4. UNCERTAINTIES IN CARBON FLUX ESTIMATION UNCERTAINTIES IN TRANSPORT MODELS INADEQUATE CONCENTRATION OBSERVATIONS (GURNEY 2002)

  5. TransCom Regions

  6. The highest CO2 observatory in the world Probably the only one powered by solar energy

  7. ATMOSPH. CO2 CONCENTRATIONS AT HANLEAND FLUX ESTIMATIONS FOR TEMERATE ASIA

  8. NETWORK DESIGN FOR IMPROVED CO2 FLUX ESTIMATIONS APPROACH: MINIMISATION OF THE TRACE OF THE COVARIANCES C(S) -1 = C(So) -1 + JT C(D) -1 J OF GLOBAL OR EGIONAL SUB-MATRICES USING THE GENETIC ALGORITHM.

  9. FIGURE SHOWS GLOBAL TRACE METRIC AS A FUNCTION OF ONE ADDITIONAL STATION TO THE NETWORK OF GURNEY (2004). THE NUMBERS SHOW THE LOCATION S CHOSEN BY GA FOR 1, 2 OR 5, STATION NETWORKS WHICH MATCHES THE SCORE BEST.

  10. Stations numbered 5 are located by GA, +s are the stations originally chosen

  11. PROBLEMS REDUCTION/ ATTRIBUTION OF UNCERTAINTIES IN FLUX ESTIMATIONS BECAUSE OF INADEQUATE DATA TENDENCY FOR OPTIMAL NETWORKS IDENTIFIED BY GA TO HAVE CLUSTERING OF STATIONS

  12. C(D) = AT CT(D) + AN CN(D)[ CT(D)i ]1/2 ~ 0.32 + (0.32/M) VARi q(i,t) [ CN(D)i ]1/2 ~ NPPi exp[(- (Pi - P*)/H] Upper left figure represents the advectiveCdand the upper right , that due to PP. The lower left is the total effect
