[ncl-talk] Making Snow Storm Trajectories (reference to past e-mail)

[Adam Phillips]

Hi Barry,
Looking at the error message it looks to me that you have to add to the
list of new markers specified in lines 184-187 within the idxs array to
accommodate the change in your input files. I would recommend following
what is done in lines 156-182, either by specifying existing marker indices
(as is done in lines 156-160), or by calling NhlNewMarker. The original
author of this script set up the marker array idxs to house filled markers
in idxs(:,0) and hollow markers in idxs(:,1).

See:
