• Characterising correlation of hourly precipitation records

A package of Matlab functions for exploring spatial patterns of correlation in high resolution climate data. Cross-similarity parameters (dominant lag, max-similarity, window cross-similarity) are calculated for each pair of records and presented on maps as well as plots with an intersite distance. More about methodology here. Example figure.

• Correlation in time series of high temporal resolution

Cosine Cross-Similarity

Matlab function that calculates cosine cross-similarity between time series of threshold crossings with time lags. It also calculates dominant lag and maximum value. Plots are optional. More about methodology here. Example figure.

Window Cross-Similarity

Matlab function that calculates window cross-similarity between time series of threshold crossings for selected window span. More about methodology here.

• Trend-Duration-Frequency

Software for testing for trends in extreme high values of data series. Significance of trends is estimated for several data resolutions and several values of quantiles. More information on methodology could be found here.

Software is primarily meant for use on climate data. It is a package of Matlab functions that could be downloaded from this website together with user manuel and example data set. Alternatively from Matlab Central file exchange.
