NCO 1.2.x will continue to be maintained for its ability to work with HDF4 files, but no new features will be added. NCO version 1.2.2 is released. Previously, ncrename would rename the same attribute for all variables in a file. The effects of this last change should not be visible to the user. Differences with version 1.2 include one new feature and one bugfix.
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. A bug introduced in NCO 1.2 which broke the -x switch has been fixed 3. The names of three of the operators have been made somewhat obsolete because they are no longer just arithmetic averagers. It is also possible to compute spatial and temporal variances and standard deviations using a combination of three or four NCO commands. All operators may now be DODS clients.
