Number of days for which this activity is defined. Depending on the standard activity type, this may or may not be important/expected. Weight in tonnes for which this activity is defined. Depending on the standard activity type, this may or may not be important/expected. Cubic meter volume for which this activity is defined. Depending on the standard activity type, this may or may not be important/expected. Number of applications for which this activity is defined. Depending on the standard activity type, this may or may not be important/expected. The specific type of use or activity of the agricultural land. General description of ships on an inland shipping route. This class describes a ship on a sailing route, using a predefined ship type. Ship Type. Standard manure storage description. This class describes a standard manure storage, using a predefined manure storage technique code. Fixed code that indicates what type of manure storage technology is involved. This code is used to determine which optional features are expected. General description of ships on a maritime shipping route. This class describes a ship on a sailing route, using a predefined ship type. Ship type. General description of ships at an inland shipping mooring. This class describes a ship at a mooring, using a predefined ship type. Ship type. General description of ships at a maritime shipping mooring. This class describes a ship at a mooring, using a predefined ship type. Ship type. Characteristics of an emission type for mobile equipment. Mobile tools are described on the basis of a number of characteristics. These are recorded in this data type. Liters of fuel (summed) that this type of vehicle consumes per year. Time in hours per year that the vehicle is running. Liters of AdBlue (summed) that this type of vehicle uses per year. The power in kilowatt of this type of vehicle. The class of this mobile machinery. Temporal variation according to one of the standard values known within AERIUS (based on OPS). The standard type to be used. Due to expandability, it is not specified which values are possible, but there is a limited possibility. Characteristics of a standard vehicle type class. This class describes a standard vehicle type group for moving traffic, using a predefined vehicle group code. Fraction of traffic that is stagnant. Maximum speed in kilometers per hour. Presence of strict speed enforcement. The class of this standard vehicle group. Subpoint for a receptor point. This class describes a sub-calculation point of a receptor point on the AERIUS grid. The level at which this sub-calculation point is determined. The closer to a source, the higher level and the more sub-calculation points are used for the receptor point. Identification number of the subpoint. Identification number of the receptor point on which this sub-calculation point is based. List of different substance names. The AERIUS calculation core can calculate emissions for a number of substances, which are listed here. NH3 (ammonia). NOx (nitrogen oxides). NO2 (nitrogen dioxide). PM10 (particulate matter with a diameter less than 10 microns). PM2.5 (particulate matter with a diameter less than 2.5 microns). EC (elemental carbon). Combination of NOx and NH3, mostly used for Nitrogen deposition as a result of these substances. List of different time units. The AERIUS calculation core can calculate emissions based on time units, which are listed here. Temporal variation. List of different directions for traffic on roads. For a road, it can be indicated in which direction the traffic travels on the line segment in relation to the drawn direction. The options are included in this list. Traffic can move in both directions. Traffic travels from A (beginning of the line) to B (end of the line). Traffic travels from B (end of the line) to A (beginning of the line). List of different types of tree profile between the road and the calculation point. When calculating emissions for road traffic in suburban areas, trees along the road can be taken into account (SRM1). Trees sparse or not present. One or more rows of trees with separation of < 15 meters with gaps between the crowns. The crowns touch each other and span at least a third of the street width. Characteristics of a vehicle type. There are different vehicle types available in the model. This abstract base class is a generalization of the different types in the model. Number of vehicles per time unit. Time unit for the number of vehicles. Metadata about version used. This data type contains the versions used to arrive at the data. Version number of the AERIUS model core. Version number of the AERIUS database. Options for the flow direction of routes for inland vessels. The flow for an inland shipping route can count towards the emission factors, depending on the waterway type. If not relevant, the flow direction is determined as the drawing direction. Flow is not important. Against the flow. With the flow.
