1dVar array direction tests

[Huw Lewis]

Changes to ropp_1dvar at v1.2 ensure data are translated to be increasing with height. This is a reminder to add checks/functionality if data are input in the opposite direction, and necessary conversions to error covariance data can be made.

This needs testing in more detail (e.g. see /tests/test_1dvar.sh processing, now fixed to compare input with ROTATE(output,2).)

Milestone 3.0 deleted

At ROPP-3, have added message output in ropp_io/ropp_io_ascend to alert users when the input data is not in ascending height order (and the implications for 1dVar use). See [2125]. User Guide documentation has also been modified to clarify this point following beta test feedback.

Automatic conversion of error correlation files for 1dVar, if input data is in the wrong order is perhaps a bit too dangerous. The warning message is perhaps sufficient to alert users to modify their correlation file manually, where they will then be aware what it is they are doing! The errors/README file also includes the required height order (see [2142]).

Ticket closed as fixed.
