Global Satellite Mapping of Precipitation (GSMaP) fornisce
un tasso di pioggia orario globale con una risoluzione di 0,1 x 0,1 gradi. GSMaP
è un prodotto della missione Global Precipitation Measurement (GPM),
che fornisce osservazioni globali sulle precipitazioni a intervalli di tre ore. I valori vengono stimati utilizzando radiometri a microonde passivi e infrarossi multi-banda
dal satellite GPM Core Observatory
e con l'aiuto di una costellazione di altri satelliti. L'algoritmo di recupero del tasso di precipitazione di GPM si basa su un modello di trasferimento radiativo. Il tasso aggiustato del misuratore viene calcolato in base
all'ottimizzazione dell'accumulo di 24 ore del tasso di pioggia orario GSMaP
alla precipitazione giornaliera mediante la misurazione del misuratore NOAA/CPC. Questo set di dati
viene elaborato dall'algoritmo GSMaP versione 6 (versione 3 del prodotto).
Per ulteriori dettagli, consulta la documentazione tecnica di GSMaP.
È disponibile anche il set di dati operativo GSMaP (dal 2014 a oggi).
