The role of rainfall raingauge observations in calibration of radar derived rainfall estimates is investigated. The final goal is the reconstruction of the rainfall fields over the observed area using both information during a rainfall enhancement experiment. Furthermore, we propose a simple protocol to assess the experiment efficacy. A space-time approach and the use of kriging with external drift are applied and compared. Results are again compared with those one obtained through an ordinary kriging (OK). Data come from a dense raingauge network and a weather radar installed in 1992 for the evaluation of a rain enhancement experiment carried out in Southern Italy. In this paper we report detailed results from one seeding operation carried out on 11 April 1992. The procedure to assess the efficacy of rain enhancement experiment is illustrated for 11 seeding operations.
