ILAMB datasets

ILAMB datasets are resampled at 0.5° which seems a big limitation when looking at regional and high-resolution simulations.

Ideas for additional datasets for ILAMB:

  • Urban flux tower data
  • Reanalyses: BARRA - But is that useful if it does not assimilate land properties?
  • CSIRO ET product on TERN, and other TERN datasets
  • COSMOZ in-situ observations
  • SMAP L4 gridded soil moisture
  • Land surface temperature: new datasets from satellites. Himawari. But these are still very new products and it’s not certain how useful they are yet.

ILAMB is regridding the datasets at 0.5 degree resolution. This is too low resolution for high-resolution simulations. How can we do evaluations for high-resolution simulations? We will need something else for higher time and spatial evaluation.

ESMValTool should be what we use if we want to develop other evaluation.
The issue with ESMValtool is the learning curve.

We should have a test of adding a couple of Australian datasets to ILAMB: CMRSET, AusEFlux. @clairecarouge to do that with the MED team.
