Acceptance Test for single point missing temperature values with TAN, TAX method
Step | Direction | Expected Result | Pass/Fail Criteria or Comment |
---|---|---|---|
001 | Prepare test data in the test database. | – | – |
Download Test Data and gunzip. | – | – | |
$ psql kvalobs | – | – | |
DELETE FROM data WHERE obstime>'2024-02-28' and obstime<'2024-04-01'; | – | – | |
\copy data FROM './alg004-kvalobsdb.dat' WITH DELIMITER AS '|' | – | – | |
NB specify the actual path to the test data above as required. | – | – | |
– | – | ||
Check that the time interval contains no Qc2 processed data: | – | – | |
kvalobs=# select count(*) from data WHERE obstime>'2024-02-28' and obstime<'2024-04-01' and cfailed like '%Qc2%'; | count=0 | – | |
002 | Download and gunzip alg004.cfg.gz to the Qc2Config directory and edit RunAtHour and RunAtMinute fields to the time that the test shall be run (e.g. a few minutes UTC in the future). | – | – |
The configuration by default has W_fhqc=0 and Wbool=true. The algorithm will only work on data that ha not been controlled by HQC | – | – | |
003 | Check log files to verify that the algorithm runs as scheduled, e.g. $ tail -f /metno/kvalobs/var/log/Qc2.log | – | – |
004 | Check that Qc2 processed data now resides in the database: | – | – |
kvalobs=# select count(*) from data WHERE obstime>'2024-02-28' and obstime<'2024-04-01' and cfailed like '%Qc2%'; | count=55 | – | |
005 | Delete any existing data output (rm ALG004-Step5.dat) and then EXTRACT THE DATA: | DATA-S5 | – |
psql> select * from data WHERE obstime>'2024-02-28' and obstime<'2024-04-01' and cfailed like '%Qc2%' \g | cat >> ./ALG004-Step5.dat;
006 | Plot the data. Download and use the two scripts ./unit_t_plot.bash and unitt.r.gz | – | – |
./unit_T_plot.bash ALG004-Step5.dat | ![]() | – | |
and inspect the produced image ALG004-Step5.dat.jpg file. | – | – | |
007 | Edit the configuration file and set Wbool=false. Rerun the algorithm. The algorithm will reprocess the data flagged as controlled by HQC already. | – | – |
kvalobs=# select count(*) from data WHERE obstime>'2024-02-28' and obstime<'2024-04-01' and cfailed like '%Qc2%'; | count=121 | – | |
Capture the results. (rm ALG004-Step7.dat any previous test results) | DATA-S7 | – |
psql> select * from data WHERE obstime>'2024-02-28' and obstime<'2024-04-01' and cfailed like '%Qc2%' \g | cat >> ./ALG004-Step7.dat;
Prerequisites
Set up the test data (these are prepatory notes for now for set up on pak)
Test Data comprising original data from 2008-03 with all the years set to 2024, the file only contains the parameters for the algorithm.
Setting-up or refreshing the database. (some database management may be required to stop page errors and the like ????, vacuum cleaning etc ???)
- $ psql kvalobs
- psql⇒ DELETE FROM data WHERE obstime>'2024-02-28' and obstime<'2024-04-01';
- psql⇒ \copy data FROM ./alg004-kvalobsdb.dat WITH DELIMITER AS '|';
Script for plotting the test results. See the Step # above: unit_t_plot.bash.gz
… and not to forget the corresponding R-script called by the shell script: unitt.r.gz
