  abstract = {{T}his study analyses the response of the continental surface to rain events, taking advantage of the long-term near-surface measurements over different vegetation types at different latitudes, acquired during the {A}frican {M}onsoon {M}ultidisciplinary {A}nalysis ({AMMA}) by the {AMMA}-{CATCH} observing system. {T}he simulated surface response by nine land surface models involved in {AMMA} {L}and {M}odel {I}ntercomparison {P}roject ({ALMIP}), is compared to the observations. {T}he surface response, described via the evaporative fraction ({EF}), evolves in two steps: the immediate surface response (corresponding to an increase of {EF} occurring immediately after the rain) and the surface recovery (characterized by a decrease of {EF} over several days after the rain). {I}t is shown that, for all the experimental sites, the immediate surface response is mainly dependent on the soil moisture content and the recovery period follows an exponential relationship whose rate is strongly dependent on the vegetation type (from 1 day over bare soil to 70 days over forest) and plant functional type (below and above 10 days for annual and perennial plants, respectively). {T}he {ALMIP} model ensemble depicts a broad range of relationships between {EF} and soil moisture, with the worst results for the drier sites (high latitudes). {T}he land surface models tend to simulate a realistic surface recovery for vegetated sites, but a slower and more variable {EF} decrease is simulated over bare soil than observed.},
