<div dir="ltr">As the error suggests, you must have both the X and Y dimension environment varying. You set the latitude to a constant, so that is where your error is. You need to set the latitude to a range instead of a constant.<br>

I need the value of the vorticity at each grid point of my domain. The<br>
error I found when doing a test is shown below.<br>
<br>
ga -> set lat -30.0276<br>
LAT set to -30.0276 -30.0276<br>
ga-> set lon 307.994<br>
LON set to 307.994 307.994<br>
ga-> d hcurl(u(lev=500),v(lev=500))*1e5<br>
Error from HCURL: Invalid dimension environment<br>
Horizontal environment (X, Y varying) is required<br>
Operation error: Error from hcurl function<br>
Errror occurred at column 1<br>
DISPLAY error: Invalid expression<br>
<br>
What can I do to fix this? Please, help me!<br>
Thanks,<br>
