1. Model Evaluation Databases (MED)

This chapter presents the characteristics of selected evaluation databases of dispersion models. Databases are provided by Support Center for Regulatory Atmospheric Modeling (SCRAM). The full list of model evaluation databases is presented in Table 1.

Table 1: Model Evaluation Databases.

1.1. Graphical representation of the research area

Description of the markings:

  • Emitters - source of air pollution emission,
  • Monitor - Air Monitoring Stations (AMS) or the location of sampling SF_6,
  • Sodar or met. tower - meteorological data on site,
  • ISD - Integrated Surface Database (link),
  • IGRA - Integrated Global Radiosonde Archive (link), (downland RAOBS),
  • Precip - Hourly Precipitation Data (DSI-3240).

2. Spatial data

2.1. Introduction

This chapter presents the visualization of the numerical terrain model and land cover data. Data for different horizontal resolutions has been compiled. The table below shows the data sources and basic model settings.

Markings of table headings: DEM - Digital Elevation Model, LC - Land Cover, DGRID - Grid Spacing (grid resolution), DX - The width of the grid in kilometers, DY - The height of the grid in kilometers, MC - Martin’s Creek power plant, LV - Lovett power plant, TR - Tracy power plant.

Database shortcuts: STRM3 - Shuttle Radar Topography Missiom, (downland), NED - USGS National Elevation Dataset, (downland), NLCD92 - National Land Cover Dataset, [(description)](https://www.mrlc.gov/nlcd1992.php, GLC - Global Land Cover Characterization, (description), GTOPO30 - Global 30 Arc-Second Elevation, (description).

Data contained on interactive charts are the output from the MAKGEO pre-processor. It is a processed form of original data sets.
