Detailed Description

A list of meteorological stations.

Can find the nearest station for a position and calculate the temperature lapse

◆ add_station()

MeteoStation::ptr add_station	(	std::string	name,
		cmf::geometry::point	position,
		double	latitude = 51.0,
		double	longitude = 8.0,
		double	tz = 1.0,
		cmf::math::Time	startTime = cmf::math::Time(1, 1, 2001),
		cmf::math::Time	timestep = cmf::math::day )

Creates a meteorological station at a certain position and adds it to the list.

Parameters

name	Name of the station
position	The location of the station in map coordinates
latitude	Latitude of the study area (for solar radiation)
longitude	Longitude of the study area (for solar time)
tz	Time zone of the study area (e.g Germany +1,U.S. Pacific time -8
startTime	Date of the beginning of the climatic data (may be changed for each time series later)
timestep	Frequency of climatic data (may be changed for each time series later)

◆ calculate_Temp_lapse()

double calculate_Temp_lapse	(	cmf::math::Time	begin,
		cmf::math::Time	step,
		cmf::math::Time	end )

Calculates the temperature lapse from all stations in the list and sets the T_lapse attribute of each station.

Returns the average lapse over the whole period.

◆ reference_to_nearest()

MeteoStationReference reference_to_nearest	(	const cmf::geometry::point &	position,
		double	z_weight = 0 ) const

Creates a MeteoStationReference from the nearest station to position at position.

The distance is calculated as \( d=\sqrt{(x_{s} - x_{l})^2 + (y_{s} - y_{l})^2} + \lambda_z\|z_{s} - z_{l}\| \) Where \(s\) is the station and \(l\) is the locatable

Returns: A Meteorology using the data of the nearest station to position
