Based on your feedback regarding the correction to the 1901-1947 Princeton data, the following decisions has been reached:
* /All/ biomes models will re-run the Princeton data set due to the significant effects on the outcomes of the model spin up.
* We recommend that other models that have used the
1901-1947 data also re-run these simulations ...
As we reported to you at the end of last year, the Princeton data set
provided to you for use in the ISI-MIP simulations for the period
1901-1947 has been superceded by a corrected version. The problem was a mistake in the processing scripts, not a systematic methodological mistake, so the data were just wrong ...
