    112    * Some AMIP runs use a prescribed climatology of vegetation properties; vegetation fractions, leaf area index (LAI) and canopy height. These climatologies were constructed from data from the UKESM1-0-LL DECK or historical simulations, but in certain simulations the seasonal cycle of LAI used was found to be incorrect and is six months out of phase. This error has been corrected with a new LAI climatology file at [https://code.metoffice.gov.uk/trac/roses-u/browser/b/e/3/0/3/trunk?rev=147944 147944 of the suite].  Working copies of the suite should be updated to use this revision.

    114114   * All Stash items spanning '''`38:485 to 38:545`''': `Aerosol surface conc., concn., load diagnostics`: Due to the way STASH is handling and processing these items, they will be output as exactly '''1/3rd of their actual value'''. The values of these items must therefore be scaled by a factor of 3.0.
