Model Parameter Configuration

Dynamic calibration — all changes apply live without editing source code

⚠ Unsaved changes
Carbon Potential Regression Model
Linear regression between Sentinel-2 NDVI Red-Edge and carbon potential density. Used to compute NFC_DATA.potC and drive the right-panel NFC charts. Change coefficients when a new field-calibrated model is available.
Pot.C = a × NDVI − b
Negative value: carbon offset when NDVI = 0
Displayed in NFC panel header
Below this value, model extrapolation uncertain
Pot.Carbon = 1519.9 × NDVI − 67.202 (tC/ha)
R² = 0.7239   |   At NDVI 0.60 → 844.7 tC/ha   |   At NDVI 0.65 → 921.7 tC/ha
Above-Ground & Below-Ground Biomass Model
Allometric model relating Sentinel-2 NDVI Red-Edge to biomass carbon stocks. Based on ITTO 2025 / IPCC Tier-2 methodology for tropical forest of South Kalimantan. Update when new field-calibrated allometric equations are published.
AGB = α × e^(β × NDVI_RE)
Exponential scaling with NDVI Red-Edge
IPCC Tier-2: 0.26 for tropical forest
Fraction of dry biomass that is C (0.47 IPCC)
CO₂eq = C × 3.67 (molecular weight ratio)
NDVI value for live formula preview
AGB = 83.2 × e^(2.14 × NDVI_RE)   (t DM/ha)
BGB = AGB × 0.26   (IPCC Tier-2)
C (tC/ha) = (AGB + BGB) × 0.47
──────────────────────────────────
At NDVI 0.62: AGB = 271.4 t/ha → BGB = 70.6 t/ha → C = 160.3 tC/ha → CO₂eq = 588.3 tCO₂/ha
NDVI Red-Edge Time Series (Sentinel-2 B8A/B5, May–Jul)
Edit annual NDVI values from Sentinel-2 band B8A/B5 composite (cloud-free, months 5–7). Rows highlighted in yellow are predicted (2026–2030). Applying changes recalculates Pot.C and NFC and re-renders all NFC charts.

PUP Permanent Sample Plot Carbon Parameters
Update when new field measurements become available from the KHDTK PUP network. Applying recalculates: total carbon stock, CO₂eq, annual offset, revenue estimates, and re-renders all cp-pup panel charts and tables.

NDVI Classification Thresholds & Colors
Defines how carbon map polygon colors are assigned based on NDVI Red-Edge value. Thresholds are upper bounds (values above each threshold get that class color). Applying changes immediately recolors all SVG polygons on the map.
Class 5 (lowest) always catches NDVI values ≤ threshold 4 — no upper bound needed.
Carbon Offset DSS Scoring Thresholds
The Decision Support System scores an area for ITTO 2025 carbon offset eligibility based on four components. Adjust thresholds and scores to match updated ITTO guidelines or regional standards.

Carbon Stock (max 25 pts)

≥ tC/ha → pts:
≥ tC/ha → pts:
≥ tC/ha → pts:
Otherwise → pts:

Net Flux (max 25 pts)

≥ tC/ha/yr → pts:
≥ tC/ha/yr → pts:
≥ tC/ha/yr → pts:
≥ tC/ha/yr → pts:

NDVI Red-Edge (max 20 pts)

≥ NDVI → pts:
≥ NDVI → pts:
≥ NDVI → pts:
Otherwise → pts:

Area (max 15 pts)

≥ Ha → pts:
≥ Ha → pts:
≥ Ha → pts:
Otherwise → pts:
Note: Disturbance Level bonus (max 10 pts) and Baseline Data bonus (max 5 pts) are calculated automatically from dropdown selections in the DSS modal and are not configurable here. Total possible score = Carbon(25) + Flux(25) + NDVI(20) + Area(15) + Disturbance(10) + Baseline(5) = 100 pts.
