<p class="MsoNormal"><span style="font-family:Helvetica">I have a question about plotting a map of the differences of two variables. In my script I am trying to plot the difference for total column CO between two different models. Since the total column CO
in both models are in different units I have to convert one of the species from kg/m2 to molecules/cm2. When define the variable to include the conversion the script only plots the original value of the species not the converted value. Thank you for your help
in advance. <o:p></o:p></span></p>
