Norwegian Meteorological Institute met.no Stage II Review tests – 2007 changes Overview of the internal consistency of gridded data Update of cross pollutant test 3A, by excluding the ratios NMVOC/CO and CO/NH3 for sector NFR 6A, since CO was pre-filled with “NA” for CO in reporting Table 1. Further, last year’s “Agriculture”=sector NFR 4B+4D have been re- designed to NFR 4B+4D1 in accordance with the 2004 Table 1 reporting template Internal consistency of non-gridded data is checked by REPDAB during the Stage 1 review, and has been excluded from the current Stage 2 review
