Statistical Comparisons of Past Climate Change and Future Climate Prediction

Subsequent web pages allow you to see numarical statistics of one or two derived datafile records. Derived datafile records are determined from Model decade annual datafiles (A10), Model decade monthly datafiles (M10), and observations. Each derived record can be a difference between decades, a difference between simulations, or a difference between climate variables. If a single derived datafile record is determined, then area weighted mean values and root mean square values of the record are calculated. If two records are determined, then mean differences, root mean square differences, and spatial correlation coefficients are calculated. Checkboxes to the left of a decade, simulation, model climate variable, or observation determine the first derived datafile record. Checkboxes to the right determine the second record.

The output of each statistic is a numerical table with three columns (Global, NorthHemi, SouthHemi) and 6 rows (Global, Ocean, Continent, Ground, LandIce, Lake). These tables form a web page which can be downloaded to your local disk. To see mean values for specialized regions, download the LinePlot files that are created by the Line Plot web pages.

Following is a list of Fortran programs that can produce certain statistics from datafiles on a UNIX workstation.

MEAN.FOR : prints mean values of a datafile record or the difference between two records for each hemisphere and each surface type.
RMS.FOR : prints root mean square values of a datafile record or the difference between two records for each hemisphere and each surface type.
SCC.FOR : prints spatial correlation coefficients between two datafile records for each hemisphere and each surface type.
