Environmental operators
8 operators in the environmental category of the live registry. Each is a named formula you can compose inside a state contract or call directly through POST /api/zeq/compute. KO42 is always on; add up to three more per call (total ≤ 4), per the 7-step protocol.
| Operator | Description | Equation |
|---|---|---|
AIR_QUALITY_INDEX | Air Quality Index computed as the maximum of individual pollutant sub-indices for public health communication. | AQI = max(AQI_{PM2.5}, AQI_{O_3}, AQI_{NO_2}) |
BIODIVERSITY_INDEX | Shannon diversity index H = -sum(p_i * ln(p_i)) measuring species richness and evenness in an ecological community. | H = -\sum_i p_i \ln(p_i) |
CARBON_SEQUESTRATION | Carbon sequestration rate C_seq = NPP*(1 - R_h) computing net carbon uptake from net primary productivity minus heterotrophic respiration. | C_{seq} = NPP \times (1 - R_h) |
CLIMATE_FEEDBACK | Climate feedback parameter lambda = 1/sum(f_i) aggregating individual feedback strengths into net climate sensitivity. | \lambda = \frac{1}{\sum_i f_i} |
CLIMATE_MODEL | Climate sensitivity relation delta_T = lambda * delta_F linking radiative forcing change to equilibrium temperature response. | \Delta T = \lambda \times \Delta F |
ECO_FOOTPRINT | Ecological footprint EF = sum(P_i/Y_i)*EQF_i converting resource consumption into biologically productive land area equivalents. | EF = \sum_i \frac{P_i}{Y_i} \times EQF_i |
RADIATIVE_FORCING | Radiative forcing delta_F = 5.35*ln(C/C_0) computing the change in Earth's energy balance from CO2 concentration changes. | \Delta F = 5.35 \ln(\frac{C}{C_0}) |
WATER_QUALITY | Water Quality Index WQI = sum(w_i * q_i) aggregating weighted sub-indices of pollutant concentrations into a single water quality score. | WQI = \sum_i w_i \times q_i |
Compute with one of these
curl -sS -X POST https://zeqsdk.com/api/zeq/compute \
-H "Authorization: Bearer $ZEQ_KEY" \
-H "Content-Type: application/json" \
-d '{"operators":["AIR_QUALITY_INDEX"],"inputs":{}}'
The response carries the bare physics value, its unit and uncertainty, the generated master equation, and a signed envelope you can verify on any node.
