To mirror the output resolution of the HRES and retrieve data at TCO1279, O1280 or 0.1° x 0.1° lat/long grid, the keywordsdata on the TCO7999 grid can be truncated and/or regridded. This is achieved using the following keywords:

  • 'truncation' : '1279'
  • 'grid' : 'O1280'
  • 'grid' : '0.1/0.1'

can be used for spectral, or gridded data (respectively). This will improve the download time of the spectral data but reduce the resolution of the data.

Warning
titleRegridding of data on the O8000 grid

Please note that data on the O8000 grid cannot currently be regridded and will cause the retrieval to fail.
This is because the size of the interpolation matrices for gridded data becomes too large. A parallel interpolation system is currently in development to deal with this high resolution data.
