A short demonstration on the process of rainfall measurements, using Hydrognomon double-mass module for homogeneity test and restoration. • Homogeneity test and restoration requires of rainfall data measurements from two adjacent stations (a reference station and a station put under test). Measurements should be aggregated to an annual time step. In our example a so-called hydrological year definition is used, aggregating annual rainfalls to a period starting from 1st October, lasting next year's September 30th. Extra time series can be specified from the station put in test, of finer time step, such as monthly or daily, in order to reduce them based on the results of double mass curve analysis. • More information on the method: • http://pubs.usgs.gov/wsp/1541b/report... • https://en.wikipedia.org/wiki/Double_... • Download hydrognomon: • http://hydrognomon.org
