EW_LAPMOD
The official graphical interface for the open-source LAPMOD model, covering input preparation, consistency checks, simulation support, postprocessing, and map-based visualization.
Sources, buildings, receptors, meteorological fields, and model output in one project.

Model interface
Operate a particle model through a coherent geographic project.
EW_LAPMOD makes LAPMOD inputs and outputs easier to prepare, inspect, and reuse without hiding the scientific structure of the model.
The interface reads CALMET meteorological output prepared by the user or supplied through MeteoData. Sources and discrete receptors can be entered numerically or placed on the embedded map. Input consistency checks run before LAPMOD files are created.
After simulation, receptor concentration time series can be plotted and binary model output can be processed into annual averages, percentiles, running averages, and other required statistics.
01Configure
Define particle-model sources, receptors, buildings, and emissions.
02Assemble
Merge multiple source definitions into one emission file.
03Inspect
View CALMET meteorology, terrain, and land-use information.
04Analyze
Plot receptors and produce gridded concentration statistics.
Capabilities
Prepare, run, and understand particle simulations.
Emission schedules
Configure constant, regular, and arbitrary time-varying source rates.
Source merging
Automatically combine all configured sources into a single emission file.
Building geometry
Read building footprints and geometry from KML files.
CALMET inspection
Extract meteorology at any point and plot terrain and land use.
Output visualization
Plot receptor concentrations and display gridded results over the base map.
Project workflow
Connect emissions, meteorology, simulation, and output.
The GUI coordinates LAPMOD project components while retaining direct access to the open-source modeling system.
- 01Load CALMET meteorological output for the domain.
