The netCDF operators NCO version 1.2.1 are ready.
Differences with version 1.2 include one new feature and one bugfix.
Get the new version and read the user's guide on
http://nco.sourceforge.net
Summary of changes:
1. Operators now perform automatic type conversion of integers to
doubles before arithmetic. This feature allows ncwa, ncra, and ncea
to handle averaging of longs, shorts, bytes, and chars in a more
satisfactory manner. One immediate benefit is that ncwa no longer
complains when user's try to apply weights (e.g., gaussian weights)
all less than one to the averaging of an integer (e.g., nlons).
Formerly ncwa would issue a warning, a workaround, and then dump
core (because weights converted to integers were all zeros).
Now that arithmetic is performed in double precision (rather than
in the precision of the variable), ncwa handles this situation
correctly.
2. A bug introduced in NCO 1.2 which broke the -x switch has been fixed
3. Thanks to Henry Butowsky for implementing the type conversion feature
Thanks to Ethan Davis for improving the build procedure
Enjoy,
Charlie
