gco2.dat

Download the file gco2.dat from the web page. This file contains two columns of numbers: the year from 1980 to 2017 and the average global annual carbon dioxide concentration in the atmosphere (in parts per million) over marine surface sites. The data come from the Earth Systems Research Laboratory (Global Monitoring Division) of the National Oceanic and Atmospheric Administration (which is the government agency charged with developing weather and climate forecast models; if you are interested in additional information and data set you can visit http://www.esrl.noaa gov/gmd/ccgg/trends ). The estimated standard error in the observations is 0.1 ppm Save the file in the MATLAB working directory. Then load it with dat - load ('gco2.dat'); Note: if you do not save the file in your working directory, you need to include the whole path to load it into MATLAB. For instance, if you saved your file in the C: tmp directory you can load it by entering load ('C: temp gco2.dat')
