Weather data over the course of the field experiment from 26 September 2019 to 28 February 2020 collected by a meteorological station at the INIA-Huasco experimental center in the southern Atacama Desert (Vallenar, Chile, 28°34′ S, 70°47′ W and 469 m.a.s.l.) 300 m from the field trial and by soil sensors in the field trial;

(a) daily maximum and night mean temperature; (b) daily maximum vapor pressure deficit (VPD); (c) daily total radiation; (d) daily mean volumetric soil water content (VSWC). The full irrigation and reduced irrigation treatments started at branching (35 days after sowing), but the sensor data were only available from 40 days after sowing. The colors in the figure represent the respective quinoa developmental stages.
