Climate Research Unit (CRU) Data

The Climatic Research Unit is an institution concerned with the study of natural and anthropogenic climate change.
cru_1.ncl: A basic plot of the data

gsn_csm_contour_map_ce is the plot interface that creates a cylindrical equidistant plot.

The original data is of type short, which must be converted to type float before use. We used the short2flt to do this.

cru_2.ncl: A simple panel plot.

gsn_panel is the function that allows you to put more than one plot on a page. There are many more panel examples to review and learn from.

cru_3.ncl: A more complicated panel plot.
cru_4.ncl: Variance adjusted temperature anomalies [CRUTEM2v]
cru_5.ncl: Same as example example 4 but from the Hadley Center's land/sea variance adjusted anomalies [HadCRUT2v].
cru_6.ncl: Creates a bar chart of certain variables.

There are many ways to draw bar charts.
