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.

Example Configuration Files

For this release all the configuration files need to be re-installed since the use of AlgoCode=“a number” is now replaced with Algorithm=“the algorithm name”. The changes are illustrated in the example configuration files below.

The new configuration files are held in subversion in the directory https://svn.met.no/viewvc/kvoss/kvqc2d/branches/kvqc2d-1.1.2/src/Reference/

This includes a tar file of all of the required contents for easier deployment

To install new configuration files and setup the associated cronjob:

# after logging into the operational machine as the kvalobs user

$ cd /etc/kvalobs/Qc2Config
$ rm ./*.cfg
$ rm ./*.hold
$ wget https://svn.met.no/kvoss/kvqc2d/branches/kvqc2d-1.1.2/src/Reference/cfg.tar.gz
$ tar xvzf cfg.tar.gz
$ rm cfg.tar.gz

# The configuration files are now in place.

---------------------------------------------

# In order to set up the crontab for the weekly redistribution run

$ chmod +x Redistribution_14days_off_cron.sh
$ chmod +x Redistribution_14days_on_cron.sh

# next edit the crontab and insert the following two lines
# i.e. as user kvalobs:

$ crontab -e

# insert the following lines:

23 0 * * 3 /etc/kvalobs/Qc2Config/Redistribution_14days_on_cron.sh
23 0 * * 4 /etc/kvalobs/Qc2Config/Redistribution_14days_off_cron.sh

Notes: the new scripts in cron renames “Redistribution_14days.hold” to “Redistribution_14days.cfg” every Wednesday and the sets it back to “Redistribution_14days.hold” 24 hours later.

The Redistribution algorithm will then run automatically to the following schedule:

• typically daily run at 06:35 looking at the last 4 days
• 01:20 Wednesday Night/Thursday Morning run to check the last 14 days

Example Configuration Files

*NB* Different/simpler checks applied to the neighbours (CF version 1.0.5)

# Performs simple linear interpolation for a single point replacement.
Algorithm=SingleLinear
RunAtHour=6
RunAtMinute=50   
Last_NDays=1

#[Specific Data Type and Paramters ids etc.]
ParamId=104
# Only write back the result if not prviously 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
#Flag to check if the algorithm shall be applied ...
U_2=0		

# Algorithm configuration for redistribution of accumulated precipitation
Algorithm=Redistribute
InterpCode=2
RunAtHour=6
RunAtMinute=35
Last_NDays=4

#[Time Range] The time window for when to apply the algorithm
#Start_YYYY=2010
#Start_MM=10 
#Start_DD=8
#Start_hh=6
#Start_mm=0
#Start_ss=0

#End_YYYY=2010 
#End_MM=10
#End_DD=11
#End_hh=6

#[Specific Data Type and Paramters ids etc.]
ParamId=110
TypeIds=302
TypeIds=402

#
# Only write data it it has not been analysed by HQC
# W_fhqc=9  # 9 set here because of the test data being used ...
W_fhqc=0

# Condition for running the algorithm
A_fd=2

# Flags to set on successful completion
S_fd=7
change_fmis=3->1
change_fmis=0->4

#Only interpolate the following data
I_fd=1

InterpolationDistance=50.0

The DipTest configuration comprises two files:

DipTest.cfg

# DIP-TEST
Algorithm=DipTest
RunAtHour=5 
RunAtMinute=5

#[Time Range]
Last_NDays=1

#[Specific Data Type and Paramters ids etc.]
ParValFilename="/etc/kvalobs/Qc2Config/DipTestParameters.txt"

# Only write data it it has not been analysed by HQC
# W_fhqc=9  # 9 set here because of the test data being used ...
W_fhqc=0

#Flag required for neighbour to be used for an interpolation
U_2=0

That works through the parameters and corresponding delta values specified in DipTestParameters.txt as below:
