  abstract = {{H}igh-resolution rain fields are a prerequisite to many hydrometeorological studies. {F}or some applications, the required resolution may be as fine as 1 km in space and 5 min in time. {A}t these scales, rainfall is strongly intermittent, variable in space, and correlated in time because of the propagation of the rainy systems. {T}his paper compares two interpolation approaches to generate high-resolution rain fields from rain gauge measurements: (i) a classic interpolation technique that consists in interpolating independently the rain intensities at each time step ({E}ulerian kriging) and (ii) a simple dynamic interpolation technique that incorporates the propagation of the rainy systems ({L}agrangian kriging). {F}or this latter approach, three propagation models are tested. {T}he different interpolation techniques are evaluated over three climatically contrasted areas in {W}est {A}frica where a multiyear 5-min rainfall dataset has been collected during the {A}frican {M}onsoon {M}ultidisciplinary {A}nalyses ({AMMA}) campaigns. {T}he dynamic interpolation technique is shown to perform better than the classic approach for a majority of the rainy events. {T}he performances of the three propagation models differ from one another, depending on the evaluation criteria used. {O}ne of them provides a satisfactory time of arrival of rainfall but slightly smooths the rain intensities. {T}he two others reproduce well the rain intensities, but the time of arrival of the rain is sometimes delayed. {T}he choice of an appropriate propagation algorithm will thus depend on the operational objectives underlying the rain field generation.},
