文摘

An accurate analysis of five satellite-based rainfall products over the Italian territory is proposed. The impact of the temporal frequency of MW satellite overpasses on product performances is assessed. MW-only rainfall products are found to provide accurate rainfall estimates. The integration of soil moisture-based rainfall and state-of-the-art estimates provides a more reliable product.
