  abstract = {{S}tudy region: {T}he upper part of the {G}uayllabamba and {N}apo basins (78.2 degrees {W}, 0.3 degrees {S}; 18,500 km(2)) in the equatorial {A}ndes, which are vulnerable to stress on the ecosystem services. {S}tudy focus: {T}his paper analyses the diurnal cycle of precipitation over a transect from the {A}ndes to the {A}mazon. {T}he diurnal cycle is estimated as the diurnal distribution of precipitation for 2014-2019 using records from 80 stations. {C}luster analysis performed on the diurnal cycle estimates depicts the spatial association between the diurnal and seasonal cycles of precipitation. {N}ew hydrological insights: {A} northwest-southeast spatial variation in the diurnal and seasonal cycles is identified with four groups of stations. {I}n the western part, the seasonal cycles of {G}roups 1 and 2 are bimodal with precipitation maxima in the {M}arch-{A}pril and {O}ctober-{N}ovember seasons and a short drier season in {J}uly-{A}ugust. {I}n the eastern part, {G}roup 3 also presents bimodality, but a weaker seasonal cycle. {C}onversely, {G}roup 4 is unimodal with a peak in {J}une. {D}istinct diurnal cycles are observed in both drier and wetter seasons of {G}roups 1-3; no marked diurnal cycle is observed in {G}roup 4. {G}roups 3 and 4 are the most spatially heterogeneous, with an exceptional horizontal variation of 330 mm/yr/km. {T}he analysis of these variations provides insight into the atmospheric dynamics driving precipitation in this zone, and may help to better optimize the water supply system.},
