Description

In the comparisons of reference simulations for 2.2, 3.0, and 4.1, leaf phenology in tag 4.1 occurs too early in the season.

  • The mapper shows the problem is apparent in the northern lands, temperate asia, and the tropical lands (but this might be related to #883)
  • Separate analysis showed way too early bud break for PFT8 and PFT9
  • LAI is way too high over North and South Africa (looking at time series for offline simulations).

During the development of Tag4.1 phenology was tuned but not intentionally changed (except for the grasslands). So, one approach to get started on this problem is to run Tag 4.1 with as many ORC3 phenology parameters as possible.
