# Index of /MATLAB/SeeForcing

This directory contains MATLAB scripts and .csv data for visualizing the
correlation of HadCRUT4 with CO2 forcing defined as log2(CO2/280).
Key files are as follows.

sf.m: The MATLAB script that does the work.
Further instructions at top of file.

Data files: CO2.csv, HadCRUT4.csv, TSI.csv. Each has 147 lines of
data, one datum per line, for the years 1868-2014 inclusive.

CO2.csv: Mandatory file with 2 columns. Any source
of CO2 data is fine. The one provided here is Law Dome for 1868 to 1960
and the Mauna Loa Keeling curve thereafter.

The main output is this figure (right click
and select "Open Link in New Window") showing the
five curves named in the legend. The important points to note are:

It follows that the 0.4 °C rise in 11-year HadCRUT4 can be split
2:1, with the 2 parts associated with whatever the 65-year filter
removed and the 1 part with GHG forcing (0.082 °C) and solar
forcing (0.055 °C)
