kvqc2 Version: 1.0.5

https://svn.met.no/viewvc/kvoss/kvQc2/branches/kvqc2-1.0.5/

Algorithms in this release:

AlgoCode	Name	Description
10	SingleLinear	Replaces a single missing value with a linear interpolated value. If a corresponding max or min paramids are also specified then checks that the correction lies within the available max ... min range, if the interpolated values falls outside this range then the algorithm sets the corrected value to the nearest of max or min. Run for any paramid and optional max, min specified in the configuration file. source. Note, there is no change to this algorithm as compared with version 1.0.4 however the initia settings in the configuration file are updated (see below).
7	FlagTester	source Details provided with the example configuration file below.

Example Configuration Files

SingleLinear

# AlgCode 10 corresponds to https://svn.met.no/kvoss/kvQc2/branches/kvqc2-1.0.1/src/algorithms/SingleLinear.cc
# Performs simple linear interpolation for a single point replacement.
# If the result is outside an available max min range, the nearest of the
# max or min values are used.
AlgoCode=10
# Time to run the algorithm
RunAtHour=16
RunAtMinute=47
# Check data from the last three days
Last_NDays=40
#[Specific Data Type and Paramters ids etc.]
ParamId=211
MaxParamId=215
MinParamId=213
# Only write back the result if not previously controlled
W_fhqc=0
#Flag to set if value is corrected
S_ftime=1
change_fmis=3->1
change_fmis=0->4
change_fmis=2->4
#If there is already a 1 in place then we do not want run the algorithm again!
Not_ftime=1 #
Not_fnum=6 # This is to cut out the data with large values
U_2=0

FlagTester

This is a small utility to help check the behaviour of flag settings with the introduction of Qc2. Procedure:

Provide a set of input flags in a text file as “controlinfo useinfo” pairs

Add to the configuration file the desired conntrolinfo changes to apply.

The algorithm changes the controlinfo and then obtains an update to the useinfo from kvUseInfo::setUseFlags based on the values in the controlflag.

The results are written to a text file for later inspection.

Spatial Interpolation

No algorithms in this release perform any spatial interpolation hence the InterpCode configuration parameter, if set, has no effect.
