It contains the following files:

readme.txt						- This file
compress_ratio_mopex.m			- A matlab function to analyze the compressibility of various signals and supplied time series using existing compression techniques
/arj							- folder to install the arj software (needed for compress_ratio_mopex.m), contains link to download page.
/7zip							- folder to install the 7zip software (needed for compress_ratio_mopex.m), contains link to download page.		
/wavpack						- folder to install the wavpack software (needed for compress_ratio_mopex.m), contains link to download page.
results_P_8bits.csv  			- csv file with the resulting file sizes for P of the mopex compression experiment
results_P_6bits.csv 			- same, but with 6 bits quantization
results_Q_8bits.csv 			- for log(Q), with 8 original bits quantization
results_Q_6bits.csv 			- same, but with 6 bits quantization 
basin_info.csv                  - some background data on the basins and gauges: USGS gauge number,latitude, longitude, area of basin, Koeppen climate class for gauge location, hydrological ratios   
                					Koeppen climate classes are based on :
									Kottek, M., J. Grieser, C. Beck, B. Rudolf, and F. Rubel, 2006: World Map of the Kppen-Geiger climate classification updated. 
									Meteorol. Z., 15, 259-263. DOI: 10.1127/0941-2948/2006/0130.
*.xls							- excel versions of the csvfiles
