1881 | !! General idea |
---|
1882 | ! The established proxy vegetation has a fraction of 'veget_max_pro'; the |
---|
1883 | ! existing iPFT has a fraction of veget_max(ipts,ipft). |
---|
1884 | ! Suppose we want to merge a scalar variable B, the value of B after merging |
---|
1885 | ! is (Bi*Vi+Bj*Vj)/(Vi+Vj), where Vi is the original veget_max, Vj is the |
---|
1886 | ! incoming veget_max. Note that in case Vi=0, this equation remains solid, |
---|
1887 | ! i.e. the veget_max after merging is Vj and B after merging is Bj. In other |
---|
1888 | ! words, the proxy vegetation "fills" up the empty niche of iPFT. |
---|
1889 | ! Also note that for many scalar variables our input value is Bj*Vj, which |
---|
1890 | ! is accumulated from multiple ancestor PFTs. |
---|
1891 | veget_old = veget_max(ipts,ipft) |
---|
1892 | veget_total = veget_old+veget_max_pro |
---|
1893 | |
---|
1894 | !! Different ways of handling merging depending on nature of variables: |
---|
1895 | |
---|
1896 | !! 1. Area-based scalar variables, use the equation above |
---|
1897 | ! biomass,carbon, litter, bm_to_litter, co2_to_bm, ind, |
---|
1898 | ! lm_lastyearmax, npp_longterm, lm_lastyearmax, |
---|
1899 | ! lignin_struc (ratio variable depending on area-based variable) |
---|
1900 | |
---|
1901 | !! 2. Variables are tentatively handled like area-based variables: |
---|
1902 | ! leaf_frac, leaf_age, |
---|
1903 | |
---|
1904 | !! 3. Variables that are overwritten by the newly initialized PFT: |
---|
1905 | ! PFTpresent, senescence |
---|
1906 | |
---|
1907 | !! 4. Variables whose operation is uncertain and are not handled currently: |
---|
1908 | ! when_growthinit :: how many days ago was the beginning of the growing season (days) |
---|
1909 | ! gdd_from_growthinit :: growing degree days, since growthinit |

1910 | ! gdd_midwinter, time_hum_min, gdd_m5_dormance, ncd_dormance, |
