Fig. 1: Multi-annual (1986-2000) mean of FS - FTOA (referenced as DIV).
(a) DIV is adjusted (add a contant) to keep area mean FS = 0 over land.
(b) DIV over ocean is adjusted (add a constant) to make sure global mean DIV = 0.
Note: Mean CERES TOA flux over land (~-19W/m2 is used. (BUT mean TOA flux value over land is from each model in yesterday's plot (15/06/2015)).

(a) from 4 datasets (ERAINT, ERA20C, 20thCR, JRA55).
(b) from 5 datasets including MERRA.

Fig. 1: Multi-annual (2-001-2005) mean of net downward surface energy flux.
(a) from mass-corrected ERAINT energy divergence.
(b) from mass-corrected MERRA (from Michael Mayer) energy divergence.
Both estimations use same TOA input and total energy tendency.

Fig. 2: Difference of multi-annual (2-001-2005) mean of net downward surface energy flux.
Fres is our old calculation (incorrect), Fres-new is correct one using Michael's forecasted total energy tendency. Fmass is from mass corrected ERAINT energy divergence, and Fmass-MERRA is from mass corrected MERRA energy divergence provided by Michael.
