Data and code from: A non-parametric study of temperature trends in Fiji over five decades

Small Island Developing States (SIDSs) like Fiji are highly vulnerable to climate change, yet long term, localized analyses of temperature trends remain limited. This study investigates annual mean minimum (Tmin ), maximum (Tmax), and average (Tavg) temperature trends across 23 meteorological stations in Fiji over the period of 1970 to 2023, using the Mann-Kendall (MK) test, its modified variant (MMK) for accounting for autocorrelation, and the Sen's Slope (SS) estimator. The results reveal widespread and statistically significant warming, with 57 % of stations showing increases in minimum temperature (e.g., Vunisea: 0.33 °C/decade; Laucala: 0.30 °C/decade) and 78 % in maximum temperature (e.g., Navua: 0.61 °C/decade; Viwa: 0.55 °C/decade). A majority of the stations (91 %) recorded rising average temperatures, with the strongest warming observed in coastal and low-lying regions. Tmax exhibited the most intense warming at specific locations (e.g., Viwa, Yasawa, Navua), while T min showe..., , # Data and code from: A non-parametric study of temperature trends in Fiji over five decades
