[ncl-talk] Paleo maps in NCL?

[Buzan, Jonathan]

Hi Brian,

This is typically what I do.
Assuming you have netcdf files from a GCM:

oro = MASTER->$LANDFRAC$
orolat= MASTER->$LAT$
orolon= MASTER->$LON$
;;;;;;;;;;;;;;;;;;;Create Land Map file for Eocene;;;;;;;;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
basename = "./maps/"+filename
landmask = 1
paleo_outline (oro(0,:,:), orolat, orolon, landmask, basename)


Then in specific plot resources:
    res at mpDataSetName = basename


These commands should produce the correct continental boundaries dependent on your landfrac from your data.

Cheers,
-Jonathan

Hi Brian,

NCL does not directly supply such maps, but it can read and display content from shapefiles, and I would have to imagine you can track down base maps in that format. See the link below for how to incorporate shapefiles into your plots:

Are there any paleo geography maps available in NCL?  I’m specifically looking to plot lat-lon data over continental outlines for the end-Permian era.

Thanks!
