Xij–q50j>f*IRj Eq (1) where, Xijis the observed values on i date in j month. q50j is the median (or the 50th percentile) in j month. f is the multiplication factor (f = 5). IRj is interquartile range (75th percentile minus 25th percentile) in j month. After data have been passed the quality control, the temporal homogeneity test was carried out using RHtestsV4 software developed by Climate Research Division of Atmospheric Science and Technology Branch of Canada 17. This method detects and adjusts for the multiple change points based on the pernalized maximal T test and penalized maximal F test which are embedded in a recursive testing algorithm. D. Calculating Extreme Indices Expert Team on Climate Change Detection, Monitoring, and Indices (ETCCDMI) has defined a core set of 27 extreme indices for temperature and precipitation with user friendly R-based software, RClimDex. All of the extreme indices (seven for temperature and nine for precipitation, Table 2) are computed from the daily observation of temperature and precipitation using RClimDex software 18. These indices are recommended by the Climate Variability and Predictability (CLIVAR) as well as adopted by the IPCC AR4.
