Here I am looking for getting variable (tasmin_diff) values for eight different locations. I was expecting 12 different month tasmin_diff values for each of these eight location. But with the syntax used, it resulted other latitude and longitude combination values as well. Since I have many locations, it would be difficult to look each index combination one by one. Is there any way to get only the value for specified location only or not in combination of provided latitude and longitude using NCL?<br>
