-====== QC2 Kvalobs Meeting Acceptance Test & Other Possible Tests ======
+====== QC2 Acceptance Test & Other Possible Tests ======
+Subject: Acceptance test of precipitation re-distribution algorithms in QC2 (if precip. missing for >= 1 days)
+Participants: Per-Ove, Solfrid, Ole Einar, Matthias (author of this page)
+Not present: Paul
+===== Issues discussed: =====
+  * Test with different kinds of precipitation data: Convective, terrain (complex/flat), proximity to Swedish border
+  * Precipitation measurements have already 10% measurement inaccuracy; good result if we can achieve a certain (yet unknown) percentage accuracy in estimated values
+  * Convective case especially challenging: Half of stations could have precipitation, other half not.
+  * Automatic QC2 should give better result than HQC --> Could this be tested? (Hypothetical HQC test dataset could be used and compared with automatic QC2)
+  * Tests of QC2 should be carried out using historic data. Results should be compared with measurements.
+  * We have enough data for extensive evaluation and reliable statistical error estimations.
+  * Should HQC still check results of automatic QC2 (probably not feasible)
+  * Is QC2 giving better results than values of numerical models that are stored in KDVH. --> Test this
+===== Acceptance tests with different datasets: =====
+  - Precipitation type (convective/frontal)
+  - Regions/topography/catchment areas
+  - Station edensity/coverage
