Currently, the population density dataset I developed based on HYDE3.4 is the only one available that extends to 2022 (the end year of the CMIP7 historical run). However, HYDE3.4 does...
@ekluzek Thanks for your suggestion! I have copied the file to /glade/work/fangli/hdm1850-2023-FangLi-250211.nc
Three groups developed future population datasets. CMIP7 is still discussing which dataset will be used and how to link with the HYDE historical data. They want a population dataset that...
@ekluzek Hi Erik, the new historical population density data is located at /glade/u/home/fangle/clmforc.Li_2025_CMIP7_hdm_0.5x0.5_simyr1850-2100_c250717.nc Details about the data: The hdm for 1850–2025 is based on CMIP7 forcing: /data/feikc/data/cmip7_inputdata/hist/pop-dens_input4MIPs_population_CMIP_PIK-CMIP-1-0-0_gr_1850-2025.nc. After 2025, the...
@wwieder Thanks for the questions. 1. The figure below shows the difference between CMIP6 and CMIP7 (CMIP7 - CMIP6 for 2000–2010). Note that the CMIP7 population density differs from HYDE3.4...
@samsrabin @ekluzek @wwieder Sam requested a figure demonstrating the impact of the O₂ limit. The attached figure displays the spatial distribution of the annual burned area fraction. Observations (obs) represent...
> Thanks, Fang! I'm assuming that's for 2001-2020 or so? Hi Sam, this is for 2001-2014 and CTSM5.2 with fire scheme updates forced by CRUJRA. I'll check the CTSM5.3 outputs...
@samsrabin Source: Li et al. (2024, in prep.) will describe this. The parameters are calibrated based on the observed relationship between the burned area and o2 partial pressure. In CNFireLi2024Mod,...
@wwieder Thanks for the information. I agree that the modification mainly affects fire simulations, and has limited influence on the climate. I also agree that both the limitation of oxygen...
@ekluzek The difference between fire_emission_factors_78PFTs_c20220111 and /glade/derecho/scratch/fangli/firedata/fire_emission_factors_78PFTs_c20240624.nc is only Comp_EF (fire emission factors) in the two data files
