Detecting irrigation events over semi-arid and temperate climatic areas using sentinel-1 data: case of severalsummer crops

HIGHLIGHTS

SUMMARY

    Since models built using S1 data for irrigation detection rely on change detection between the consecutive S1 images, the revisit time of the satellite is the most important factor that limits the irrigation detection capability. As discussed in the manuscript and validated in previous studies, the maximum time delay between the irrigation event and the next S1 image to detect the irrigation event must not exceed 4 days. Le Page et_al, Ouaadi et_al and Bazzi et_al showed that beyond three to four days after the irrigation, it becomes difficult to detect the effect of . . .
