The information of the rain-detecting radar is to be used for calculating the regional rainfall so as to improve the relevant calculation solely based on data from limited rain gauge stations.

The precision of rain gauge data is high and the spatial distribution of radar-explored data is applicable (reasonable).

雨量站实测点雨量精度高，雷达站测的数据在空间上分布合理。

"It would be most useful for countries where they don't have much rain gauge data or weather radar - in Africa for instance, they do have mobile phones, at least in areas where the population density is high enough, " he told BBC News.
