  abstract = {{A} better understanding of the hydrological functioning of irrigated crops using remote sensing observations is of prime importance in semi-arid areas where water resources are limited. {R}adar observations, available at high resolution and with a high revisit time since the launch of {S}entinel-1 in 2014, have shown great potential for the monitoring of the water content of the upper soil and of the canopy. {I}n this paper, a complete set of data for radar signal analysis is shared with the scientific community for the first time to our knowledge. {T}he data set is composed of {S}entinel-1 products and in situ measurements of soil and vegetation variables collected during three agricultural seasons over drip-irrigated winter wheat in the {H}aouz plain in {M}orocco. {T}he in situ data gather soil measurements (time series of half-hourly surface soil moisture, surface roughness and agricultural practices) and vegetation measurements collected every week/2 weeks including aboveground fresh and dry biomasses, vegetation water content based on destructive measurements, the cover fraction, the leaf area index, and plant height. {R}adar data are the backscattering coefficient and the interferometric coherence derived from {S}entinel-1 {GRDH} ({G}round {R}ange {D}etected {H}igh {R}esolution) and {SLC} ({S}ingle {L}ook {C}omplex) products, respectively. {T}he normalized difference vegetation index derived from {S}entinel-2 data based on {L}evel-2{A} (surface reflectance and cloud mask) atmospheric-effects-corrected products is also provided. {T}his database, which is the first of its kind made available open access, is described here comprehensively in order to help the scientific community to evaluate and to develop new or existing remote sensing algorithms for monitoring wheat canopy under semi-arid conditions. {T}he data set is particularly relevant for the development of radar applications including surface soil moisture and vegetation variable retrieval using either physically based or empirical approaches such as machine and deep learning algorithms. {T}he database is archived in the {D}ata{S}uds repository and is freely accessible via the following {DOI}: https://doi.org/10.23708/8{D}6{WQC} ({O}uaadi et al., 2020a).},
