Saudi Carbon Monitoring prepares emissions inventory modelling inputs in Saudi Arabia, helping facilities organise measurement and operating data into controlled source terms and scenarios for air-dispersion or impact modelling. A model is only as useful as its source terms, scenarios, meteorology and technical interpretation, so our service focuses on source evidence and scenario preparation.

Saudi Carbon Monitoring scopes, coordinates and manages the work; the modelling itself is carried out by a named qualified modeller, and formal permit or EIA modelling belongs within the responsible licensed environmental-study scope. Our input preparation does not replace the permit, approved method or regulatory decision that applies to your project.
Translate facility sources into modelling inputs
The source inventory distinguishes point, area, volume, line or other source representations as the modeller requires. For stacks, inputs can include location, release height, diameter, exit velocity or flow, temperature, pollutant rate and operating schedule. Flares, tanks, material handling, road traffic and fugitive areas need source-specific representations and assumptions.
Measurements are aligned to a modelling scenario. A stack test at one load cannot be assigned to every operating condition without review. Intermittent releases, start-up, shutdown and upset cases may require separate treatment. The modeller and facility agree which scenarios answer the study question.
Establish a controlled source-term basis
Each source term records the original evidence, units, conversions, averaging period, operating condition, calculation method, assumptions and reviewer. Where a direct measurement is unavailable, an approved factor, material balance or engineering estimate may be used if suitable for the intended study. The limitation and uncertainty remain visible.
Meteorological, terrain, building-downwash and receptor data are specialist modelling inputs selected by the modeller. Model software, authority acceptance and interpretation sit with the named modelling party and scope.
Compare scenarios without overstating precision
Scenario modelling can help explore how source changes, control performance, throughput or operating schedules may affect predicted concentrations. Results are conditional on the inputs and model configuration. A predicted difference is not a guaranteed real-world outcome, and model uncertainty should be discussed alongside source-data uncertainty.
For regulatory permitting or environmental impact assessment, the engagement is routed to the responsible environmental-study provider and current Saudi authority requirements. For internal performance work, define the decision threshold and whether additional measurement would materially improve confidence.
Connect source evidence to stack testing, flare sampling, fugitive measurement and QA/QC. Keep formal regulatory modelling separate from a preliminary scenario screen.
Scope information
Provide the Saudi location, model purpose, authority or internal audience, facility and source maps, stack data, emissions inventory, operating scenarios, earlier tests, terrain/building information, available meteorology, pollutants, receptors, planned changes and required date. State whether the work is a screening comparison, detailed technical study or regulatory submission. Inputs can be prepared for projects across Saudi Arabia, including Dammam, Jubail and Riyadh.
Source-data review with the modeller
Hold a structured handover before model setup:
- For every source, confirm geometry, release parameters, emission rate, averaging basis, schedule and scenario.
- Resolve mismatched units and coordinates at this stage.
- Mark values derived from tests, monitoring, factors or assumptions so sensitivity work can focus on the weakest material inputs.
- Create a scenario table that separates routine operation, maximum credible permitted or design conditions, start-up/shutdown and proposed changes as applicable, stating why each case exists and which decision it supports.
- Agree how variable or intermittent sources are represented and what meteorological or receptor inputs remain the modeller’s responsibility.
When modelling is complete, compare the issued input inventory with the controlled handover version and document changes. That reconciliation reduces the risk of a technically polished result being based on obsolete or unapproved source terms.
Final input-control gate
Before the modeller begins, freeze an approved input register and assign a unique version. Check source coordinates, identifiers, units, averaging periods and scenario labels against the facility map. Record every later change with its origin and technical approval. When results are issued, retain the exact input set used so future reviewers can reproduce the study and distinguish a source-data revision from a model revision.
Frequently asked questions
Who provides emissions inventory modelling inputs in Saudi Arabia?
Saudi Carbon Monitoring provides emissions inventory modelling inputs in Saudi Arabia by organising source evidence, scenarios and the controlled input register.
Does this service include a formal dispersion model?
Only when a named modeller and an agreed modelling scope are included. The base service prepares and controls measurement inputs.
Can a model replace source measurement?
No. A model needs source terms, which may come from measurements, appropriate factors or other defensible estimates selected for the purpose.
How do I prepare inputs for an air-dispersion model?
Start with the source inventory and the question the study must answer. The modeller and client define the operating cases based on the applicable requirement and credible facility operations.
Can carbon dioxide and air pollutants use the same model setup?
Not automatically. Pollutant properties, objectives, averaging periods and applicable methods differ. The specialist defines the approach.
What affects the cost of modelling input preparation?
Cost depends on the number of sources and scenarios, the availability of measured data, the data gaps to be closed, and the register and handover deliverables.
How long does input preparation take?
Timing depends on the number of sources, data readiness, scenario count and review steps. Lead time is confirmed in each quotation.
Saudi Carbon Monitoring serves projects across Saudi Arabia, including Dammam, Al Khobar, Jubail, Riyadh, Jeddah, NEOM and Qiddiya.
