<div dir="ltr">What you are setting with the third parameter in new(...) is not initial values, but rather the _FillValue setting. Please read the documentation here:<div><br></div><div><a href="https://www.ncl.ucar.edu/Document/Functions/Built-in/new.shtml">https://www.ncl.ucar.edu/Document/Functions/Built-in/new.shtml</a><br></div><div><br></div><div>As a result, you are saying "missing value + 0.1 = missing_value" and then telling it to display the missing value as 1. Now, even if you set a=1, which is the proper way to initialize the variables with a single value regardless of dimensions, all values are still listed as "missing" because you've set 1 to be the value in the variable that represents having no data at any given location. Try this:</div><div><br></div><div>a=new(3,float)</div><div>b=(/.1,.2,.3)</div><div>a=1</div><div>print(a+b)</div><div><br></div><div>This should be good.
