Time series of soil moisture estimates based on in-situ measurements, the open loop (OL) simulation and the assimilation (DA) of both θSSM and fPET (between January 1, 2017 to December 31, 2017) for the: (a) first layer θ1 of the inter-row (0–5 cm), (b) first layer θ1 of the vine-row (0–5 cm), (c) second layer θ2 of the vine-row (5–30 cm), (d) third layer θ3 of the vine-row (30–60 cm), and (e) fourth layer θ4 of the vine-row (60–90 cm).
