2248 | !! General idea |
---|
2249 | ! The established proxy vegetation has a fraction of 'veget_max_pro'; the |
---|
2250 | ! existing iPFT has a fraction of veget_max(ipts,ipft). |
---|
2251 | ! Suppose we want to merge a scalar variable B, the value of B after merging |
---|
2252 | ! is (Bi*Vi+Bj*Vj)/(Vi+Vj), where Vi is the original veget_max, Vj is the |
---|
2253 | ! incoming veget_max. Note that in case Vi=0, this equation remains solid, |
---|
2254 | ! i.e. the veget_max after merging is Vj and B after merging is Bj. In other |
---|
2255 | ! words, the proxy vegetation "fills" up the empty niche of iPFT. |
---|
2256 | ! Also note that for many scalar variables our input value is Bj*Vj, which |
---|
2257 | ! is accumulated from multiple ancestor PFTs. |
---|
2258 | veget_old = veget_max(ipts,ipft) |
---|
2259 | veget_total = veget_old+veget_max_pro |
---|
2260 | |
---|
2261 | !! Different ways of handling merging depending on nature of variables: |
---|
2262 | |
---|
2263 | !! 1. Area-based scalar variables, use the equation above |
---|
2264 | ! biomass,carbon, litter, bm_to_litter, co2_to_bm, ind, |
---|
2265 | ! lm_lastyearmax, npp_longterm, lm_lastyearmax, |
---|
2266 | ! lignin_struc (ratio variable depending on area-based variable) |
---|
2267 | |
---|
2268 | !! 2. Variables are tentatively handled like area-based variables: |
---|
2269 | ! leaf_frac, leaf_age, |
---|
2270 | |
---|
2271 | !! 3. Variables that are overwritten by the newly initialized PFT: |
---|
2272 | ! PFTpresent, senescence |
---|
2273 | |
---|
2274 | !! 4. Variables whose operation is uncertain and are not handled currently: |
---|

---|
4801 | ! !! General idea |
---|
4802 | ! ! The established proxy vegetation has a fraction of 'veget_max_pro'; the |
---|
4803 | ! ! existing iPFT has a fraction of veget_max(ipts,ipft). |
---|
4804 | ! ! Suppose we want to merge a scalar variable B, the value of B after merging |
---|
4805 | ! ! is (Bi*Vi+Bj*Vj)/(Vi+Vj), where Vi is the original veget_max, Vj is the |
---|
4806 | ! ! incoming veget_max. Note that in case Vi=0, this equation remains solid, |
---|
4807 | ! ! i.e. the veget_max after merging is Vj and B after merging is Bj. In other |
---|
4808 | ! ! words, the proxy vegetation "fills" up the empty niche of iPFT. |
---|
4809 | ! ! Also note that for many scalar variables our input value is Bj*Vj, which |
---|
4810 | ! ! is accumulated from multiple ancestor PFTs. |
---|
4811 | ! veget_old = veget_max(ipts,ipft) |
---|
4812 | ! veget_total = veget_old+veget_max_pro |
---|
4813 | ! |
---|
4814 | ! !! Different ways of handling merging depending on nature of variables: |
---|
4815 | ! |
---|
4816 | ! !! 1. Area-based scalar variables, use the equation above |
---|
4817 | ! ! biomass,carbon, litter, bm_to_litter, co2_to_bm, ind, |
---|
4818 | ! ! lm_lastyearmax, npp_longterm, lm_lastyearmax, |
---|
4819 | ! ! lignin_struc (ratio variable depending on area-based variable) |
---|
4820 | ! |
---|
4821 | ! !! 2. Variables are tentatively handled like area-based variables: |
---|
4822 | ! ! leaf_frac, leaf_age, |
---|
4823 | ! |
---|
4824 | ! !! 3. Variables that are overwritten by the newly initialized PFT: |
---|
4825 | ! ! PFTpresent, senescence |
---|
4826 | ! |
---|
4827 | ! !! 4. Variables whose operation is uncertain and are not handled currently: |
---|
4828 | ! ! when_growthinit :: how many days ago was the beginning of the growing season (days) |
---|
4829 | ! ! gdd_from_growthinit :: growing degree days, since growthinit |
---|
4830 | ! ! gdd_midwinter, time_hum_min, gdd_m5_dormance, ncd_dormance, |
---|
4831 | ! ! moiavail_month, moiavail_week, ngd_minus5 |
---|
4832 | ! |
---|
4833 | ! !! 5. Variables that concern with short-term fluxes that do not apply in |
---|
