In the prescribed CLM dataset: surfdata_0.9x1.25_hist_16pfts_nourb_CMIP6_simyrPtVg_c181114.nc, I see that PCT_NAT_PFT array has dimensions (lsmlon, lsmlat, natpft), where natpft has indices 1:15. These indices refer to IVT 0-14 in Table 2.2.1 (see here). Instead, the MONTHLY_LAI array has dimensions (lsmlon, lsmlat, lsmpft, time), where lsmpft has indices 1:17. I need to calculate a total LAI, which is the weighted average of each pft LAI, based on the fraction of area covered by each LAI. To do that, however, I need to know how to map between dimensions natpdf and lsmpdf.
I'd appreciate it if anyone can help me with this.
