Climate indices calculations require at least daily resolution of homogeneous time series.

The new version MASHv3.02 (extended also for daily

precipitation data)The algorithm for daily data homogenization is as

follows:

1. Monthly values from daily data.2. MASH homogenization procedure for monthly series,

estimation of monthly inhomogeneities.3. On the basis of estimated monthly inhomogeneities,

continuous (smooth) estimation for daily inhomogeneities.4. Homogenization of daily data.5. Quality control for homogenized daily data.6. Missing daily data complementing.7. Monthly values from homogenized, controlled and

complemented daily data.8. Test of homogeneity for the new monthly series by MASH

homogenization procedure. Repeating steps if it is necessary.

ConclusionConclusion

Extreme climate indices calculations for detection of climate change require good quality, homogeneous time series

In many cases the characteristics of the estimated linear trends are unambiguously unlike on the original and homogenized time series
