Hi Michael,
I tested this NcML code, and it successfully removes an attribute from a
variable and a global attribute. The only difference in the syntax
between the two is scoping down into the variable for the variable
attribute:
<?xml version="1.0" encoding="UTF-8"?>
<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";
location="C:/Users/madry/test/RE_UBA_A1B_D3_MM_WIND_SPEED_1-1200.nc">
<remove name="unwantedGlobalAttribute" type="attribute"/>
<variable name="someVariable">
<remove name="unwantedVariableAttribute" type="attribute" />
</variable>
</netcdf>
An example is also documented on the NcML Cookbook page that will be
coming out when version 4.4.1 is deployed.

I see in the NcML cookbook how to remove attributres for specific
variables. Is there also a way to remove "Global Attributes" from a
THREDDS aggregation dataset?
https://www.unidata.ucar.edu/software/thredds/current/netcdf-java/ncml/v2.2/Cookbook.html
My reason for wanting this is that specific "history" metadata for the
2nd to last NetCDF file is creeping into the (penultimate)
aggregation. I would like to remove/clear the "history" attribute in
the Global info, or change it to a custom value within the specific
catalog.
e.g.,
http://tds.hycom.org/thredds/dodsC/GLBa0.08/expt_91.0.html
history: archv2ncdf2d for run date 2013120818
