Completion requirements
5. Compute Indicators Using Indicators Calculator Tab
5.5. Total Biomass Production (TBP)
Now we'll calculate the Total Biomass Production.
1. In the Indicator Selection dropdown, select Total Biomass Production. Formula: TBP = (NPP * 22.222) / 1000 This converts Net Primary Production (NPP) from gC/m² to biomass production in ton/ha. 2.In the Formula Parameters, select the seasonal NPP raster (WH_L3_NPP_S_2022_10_01).
3. Name the output file as WH_TBP_2022_10_01.
4. Click Calculate Indicator. The output will be saved in the Waplugin_workshop folder and displayed as a raster.
