kvqc2d Version: 1.1.2

Source: https://svn.met.no/viewvc/kvoss/kvqc2d/branches/kvqc2d-1.1.2/

Significant Changes

• Release of DipTest (including new strategy with corresponding configuration files)
• Algorithm Called by Name

In addition, it is proposed to manage the weekly run of the Redistribution algorithm with a cron.

Algorithms in this release:

(+) This is the name to specify in the configuration file.

Sample data from the new algorithm (scroll right for cfailed format)

NB on dev-vm101 this data could only be generated with I_fd=0 … normally this is set to I_fd=1 so that only QC1-controlled data is used for interpolation model values for the redistribution.

Notes

• This algorithm will redistribute data flagged with fd=2 (A_fd) and use neighbours with fd=1 for interpolation (I_fd) and set fd=7 (S_fd) for the new corrected data. But fhqc must be 0 for data to be written back.
• To re-run the algorithm on the same data again set A_fd=7 and keep W_fhqc=0, i.e. do not re-write any decision by HQC.

The schedule for the algorithm is as follows:

• 06:35 perform a run looking at the last 4 days - the last 4 days is selected since from the first run on murky (see above) about 30 redistributions were made of which 15 were over 3 days and 10 over 4 days.
• 01:20 Wednesday Night/Thursday Morning run to check the last 14 days (Note: Could we run every night for the last two weeks to pick up any changes?)
