Flag Tests

Results of testing flag handling for single missing point interpolations

Summary

The following are results obtained by preliminary tests on a development machine. For all runs ftime=1 is set for a successful interpolation. The useflag settings are set by the kvalobs Qc1 library. The test cases are based on the first parts of the circulated document (QC2-d2_flagg_08_2010_v20.doc) as described further below (amd now in the process of update after first feedback ...).

For the input control and useinfo it is not clear what all of the flag settings are likely to be. The above is based on one observed case “0000003000000000 9899900000000000” which is then further modified to include different fmis values and other flags ... as defined in the QC2-d2_flagg_08_2010_v20.doc specification. More work to be done here to identify improved test cases for trial on dev-vm101.

Betingelse
QC2-d2 skal kun brukes for interpolering av manglende verdi og korrigering av forkastet verdi. Par = TA, TAN eller TAX. Par(t) mangler (for tidspunkt t).
For disse tilfellene er:
a) fmis=1, fnum=6, useinfo(2)=9 (manglende verdi erstattet av modellverdi) eller
b) fmis=2, fnum=0 / 6, useinfo(2)=3 (forkastet verdi ikke erstattet / erstattet av modellverdi)
c) fmis=3, fnum=0, useinfo(2)=9 (manglende original- og corrected-verdi)
Foreløpig prosedyre for igangsetting av QC2-d2
1. Sjekker at Par(t-1) og Par(t+1) begge er kontrollert og funnet OK.
- useinfo(2)=0, uansett hvilke kontroller som er kjørt.
2. Iverksetter beregning av algoritme.
- Par(t) = 0.5* [Par(t-1) + Par(t+1)]
- ftime=1 (det skjer ingen endring av useinfo(2))
- for a) beholdes fmis=1 og useinfo(3), useinfo(4) endres fra 7 til 9,
for b) settes fmis=4, useinfo(3) settes til 3 og useinfo(4) settes til 9.
for c) settes fmis=1, useinfo(3) settes til 4 og useinfo(4) settes til 9.

a) fmis=1, fnum=6, useinfo(2)=9 (manglende verdi erstattet av modellverdi)

for a) beholdes fmis=1 og useinfo(3), useinfo(4) endres fra 7 til 9,
