Environmental operators

8 operators in the environmental category of the live registry. Compose them in a contract or call POST /api/zeq/compute — KO42 is always on, plus up to three more per call.

How it computes: dedicated closed-form solver solveFD — real equations over CODATA-2018 constants; where an operator needs a series/matrix/field a scalar cannot express, it refuses honestly. See the solvers.

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 one — a real call

Ask the operator which inputs it needs (the honesty contract refuses empty inputs rather than inventing them):

curl -sS -X POST https://zeqsdk.com/api/zeq/operator-spec \
  -H "Content-Type: application/json" \
  -d '{"operator":"AIR_QUALITY_INDEX"}'
