Corresponding specification for the behaviour of useinfo flags also exists but since there has not yet been Qc2 tests in operation there has been little testing of the setings. ] anonymous@undisclosed.example.com (Anonymous) kvalobs:kvoss:system:qc2 Tue, 31 May 2022 09:29:32 +0000 https://wiki.met.no/kvalobs/kvoss/system/qc2/prototype?rev=1653989372 Qc2 Prototype A prototype has been developed to tackle an example Qc2 problem: the redistribution of accumulated 24 hour rainfall measurements. Details of the problem were earlier described in presentations made at ECSN 2007 and during an internal status meeting (see slides below). anonymous@undisclosed.example.com (Anonymous) kvalobs:kvoss:system:qc2 Tue, 31 May 2022 09:29:32 +0000 https://wiki.met.no/kvalobs/kvoss/system/qc2/requirements?rev=1653989372 Requirements Specification of Qc2 Algorithms Hourly QC2h-1: PLUMATIC * Plumatic Specification Daily QC2d-1: DIP TESTS * First Specification: Detection and correction of extremes / Dip Test / ... * First Revision * Update based on [friskmelding] document and discussion. * Final version following .
