[ncl-talk] query_regarding_sine_angle

[Kyle Griffin]

Kunal,

Latitude is likely a 1-dimensional variable, while I assume your variable
is 2-dimensional (lat x lon). You can't simply multiply arrays with
different dimensions (unless it is a scalar, in which case it's not really
an array).

Look up the 'conform' function on the NCL website and you can find out how
to make your sin(lat) into an array the same shape as your var1.

Good luck.
