Description
Dear Grenville,
BAS has a 'true' high-resolution (200 m horizontal resolution) orography and land-sea mask dataset. As you might expect this shows considerable differences with the UM mean orography ancillary.
I therefore want to compute new orography ancillaries for LAM domains over regions of Antarctica using this dataset. I am aware of the Webster et al. paper and UM document 74 which explains the creation of orography ancillaries. I have also emailed Stuart Webster but haven't heard back from yet.
I was wondering if you could offer any support with this? If for example I sent you the dataset would you be able to use the MetOffice? software to create the ancillaries. Naturally the one I want to get correct is the mean orography which requires to be filtered to remove small grid-scale features.
I know you are very busy, but any help would be greatly appreciated.
Thanks,
Andrew

Dear Willie,
Stuart Webster send me a further email helping with the smoothing. It's all a lot easier than I imagined — so hopefully I won't be needing either your or Grenville's help.
Please close this ticket.
Thanks,
Andrew
