I have set my map plot setting like:<br>
res@mpProjection = "LambertConformal"<br>
res@mpLambertParallel1F = f1@TRUELAT1<br>
res@mpLambertParallel2F = f1@TRUELAT2<br>
res@mpLambertMeridianF = f1@CEN_LON<br>
res@mpLimitMode = "Corners"<br>
res@mpLeftCornerLatF = 15<br>
res@mpLeftCornerLonF = 110<br>
res@mpRightCornerLatF = 35<br>
res@mpRightCornerLonF = 140<br>
and used "gsn_csm_contour_map" to plot.<br>
<br>
Then the latitude spcing default to set to 1 degree. How can I to change the defaut setting, like 2 degree or 0.5 degree? If anyone can help me?<br>
Thank you very much.<br>
