Data Quality and Homogeneity Checks Data quality control and homogeneity are necessary for statistical analysis as climatic trends are very sensitive to errant values and outliers from numerous sources 14, 15. Prior to analysis of climate data, it is important to remove the data errors and outliers in standard methodological manner 14. In this study, the basic quality control and temporal outliers check were carried out for all data sets using 14, 15. During the basic quality control checking, the following errors such as missing value, negative precipitation value (human typing e r r o r ) , daily maximum temperature is less than or equal to daily Longitude (DD) Elevation (m) Data Availability minimum temperature, and daily maximum or minimum temperature is greater than 70°C were detected 16. All errors from basic quality control were assigned as no data. The temporal outliers check for a specific station is based on the premise that an individual monthly value should be statistically “similar” to the values of the same month from the other years. Outliers were identified by utilizing the sample distribution for each month of individual station. Extreme values are flagged out based on limited determination from a multiple of the interquartile range calculated for each station and each month using Eq (1). This procedure is common in exploratory data analysis procedures. An outlier is flagged using the formula 15; 294 Proceedings of the International Conference on Climate Change, Biodiversity and Ecosystem Services for the Sustainable Development Goals (SDGs): Policy and Practice 27-29 June 2016, Cha-am, Phetchaburi, Thailand
