Time-series of ESI, TRMMand LAI anomalies averaged over the eight
Brazilian agricultural states listed in Table 2 are shown in Fig. 3 for the
period 2003–2013 (upper plots in each panel), along with annual
state-level yield estimates from CONAB for corn (1st and 2nd growing
seasons), soybean and cotton (lower plots). The dashed lines in the
lower plots represent the linear trend for crop yields during the analyzed
period. These plots are organized geographically, according to
the regions described in Table 2. In this figure, anomalies in 3-month
index composites have been further smoothed over a 6-week moving
window to suppress noise and more clearly convey co-evolution of
yields and indices.
