FIG. 1.
MERRA atmospheric-water-budget-related variables (mm day−1) averaged on the phase space for (a) native resolution (⅔° × ½° × 1 hourly) and (b) resolution at 2.7° × 2° × 3 hourly (averaged 4 × 4 native grid cells). (left) The water budget residuals (P − E + ∂Q/∂t − QCON − QADV); (center) the MERRA analysis increments for Q; and (right) error estimates for finite differencing calculations [difference between (left) and (right)]. The phase space is spanned by QCON (abscissa) and QADV (ordinate).
