Data in black are derived from the READER dataset or more recent data and are calculated from 6-hourly synoptic data provided more than 90% of these data exist. Values in red before 1973 are monthly figures from CLIMAT messages. These CLIMAT messages have been derived from Jones and Reid (2001).

Dumont d'Urville monthly temperature statistics: this plot shows the mean, quartiles and range for each month.
(ii) Annual, seasonal and monthly trends in the Dumont d'Urville surface temperature data
The trends listed below include 95% confidence intervals. The methodology is based upon:
Santer B.D., T.M.L. Wigley, J.S. Boyle, D. J. Gaffen, J.J. Hnilo, D. Nychka, D.E. Parker and K.E. Taylor. 2000: Statistical significance of trends and trend differences in layer-average temperature time series. Journal of Geophysical Research, 105, 7337-7356.
Briefly, an effective sample size is calculated based on the lag-1 autocorrelation coefficient of the regression residuals, This effective sample size is used for the computation of the standard error and in indexing the critical values of the Student''s t distribution.
The significance level of the trend is given if it is less than 10%, 5% or 1%. With regard to summer (DJF) the year refers to the December.
