A minor revision to the National Diffusion Tube Bias Adjustment Factors Spreadsheet March 2017 (v2) is now available. Users should use this in preference to version 1 of the sheet, released in March.

Version 2 excludes one anomalous study, removed on further review and based on comments received from users of version 1. Note that the only laboratory and preparation method affected is Gradko, 20% TEA in water.

The new version can be found on the Air Quality Scotland Website LAQM Tools page and also via the Defra LAQM Support webpages.
