     12---- 
     13=== Description === 
     14Changes to lateral diffusion on momentum to allow the user to use both laplacian and bilaplacian diffusion together. This may be of use for the suppression of grid-point noise in high resolution configurations.[[BR]] This change also includes the option to use neither lateral diffusion operator for testing purposes.[[BR]] This includes an additional namelist variable to specify the background bilaplacian diffusion coefficient.[[BR]] No new cpp keys are required.

     17=== Testing === 
     18Testing could consider (where appropriate) other configurations in addition to NVTK].

     20||NVTK Tested||!'''YES/NO!'''|| 
     21||Other model configurations||!'''YES/NO!'''|| 
     22||Processor configurations tested||[ Enter processor configs tested here ]|| 
     23||If adding new functionality please confirm that the [[BR]]New code doesn't change results when it is switched off [[BR]]and !''works!'' when switched on||!'''YES/NO/NA!'''||

     32=== Bit Comparability === 
     33||Does this change preserve answers in your tested standard configurations (to the last bit) ?||!'''YES/NO !'''|| 
     34||Does this change bit compare across various processor configurations. (1xM, Nx1 and MxN are recommended)||!'''YES/NO!'''|| 
     35||Is this change expected to preserve answers in all possible model configurations?||!'''YES/NO!'''|| 
     36||Is this change expected to preserve all diagnostics? [[BR]]!,,!''Preserving answers in model runs does not necessarily imply preserved diagnostics. !''||!'''YES/NO!'''|| 
     37 
     38If you answered !'''NO!''' to any of the above, please provide further details: 
     39 
     40 * Which routine(s) are causing the difference? 
     41 * Why the changes are not protected by a logical switch or new section-version 
     42 * What is needed to achieve regression with the previous model release (e.g. a regression branch, hand-edits etc). If this is not possible, explain why not. 
     43 * What do you expect to see occur in the test harness jobs? 
     44 * Which diagnostics have you altered and why have they changed?Please add details here........
