Is your a polygon just an approximation because you don’t know how to mask using the shape file or is it really what you wanted to do?</div><div><br></div><div>In order to extract the data you can either create a new variable where you mask the region outside of the polygon or where you put all the data inside of the polygon. I would use the first approach, since what you get is a variable with the same dimensions, but maybe the second one is easier. Since you have two arrays with <font face="Menlo">lon</font>,<font face="Menlo">lat</font> coordinates can’t you just create a new variable, called <font face="Menlo">var2</font>, which is a subset of <font face="Menlo">var</font>? </div><div><br></div><div>Assuming that var has dimension <font face="Menlo">(time, lat, lon)</font> you can simply do that</div><div><br></div><div><font face="Menlo">var2=var(:,{lat},{lon})</font></div><div><font face="Menlo"><br></font></div><div>The <font face="Menlo">{}</font> means that you are using coordinate indexing, it should work also with array although I’m not 100% sure. With this method you will get a variable with different dimensions. Otherwise you can try to mask using logical staments. Assuming you have (<font face="Menlo">clon,clat)</font> coordinates in your file (I used different names because of your definition in the script) you can try something similar</div><div><br></div><div><font face="Menlo">var2=mask(var, lon.ge.min(clon) .AND. lon.le.max(clon) .AND. lat.ge.min(clat) .AND. lat.le.max(clat), False)</font></div><div><br></div><div>Cheers</div><div><br></div><div><div>
