sequence of Station	`load_stations(filename, type, origins, deltas, lengths)` Loads stations description from text file.

Function Details

Loads observations data from a file and puts it in a sequence.

Parameters:: name - Name of the file to load data from (without directory).
(type=string); directory - location of the specified file.
(type=string)

Returns:: Sequence of datetime and corresponding observation values in 1D array.
(type=datetime.datetime sequence, 1D numpy.array)

Loads observations data from files for given stations File names are guessed from station.name.

Parameters:: stations - Stations for which observation data must be returned.
(type=list of Station); directory - location of the observation files.
(type=string)

Returns:: A list of dates list (one list of dates per Station), and a list of observations arrays (one array per Station).
(type=list of datetime.datetime lists, list of numpy.array.)

Loads a specific station description from text file containing stations descriptions.

Parameters:: filename - Name of the file that describes the stations.
(type=string); type - The type of the initialization strings in the file. It could be Default, Pioneer, Emep or Bdqa.
(type=string); station_name - Name of the station to load from the file.
(type=string)

Loads stations description from text file. Removes stations outside the domain described by origins, deltas and lengths (if specified).

Parameters:: filename - Name of the file that describes the stations.
(type=string); type - The type of the initialization strings in the file. It could be Default, Pioneer, Emep or Bdqa.
(type=string); origins - (latitude, longitude) as coordinates of the first cell in the mesh.
(type=(float, float)); deltas - mesh sizes on latitude and longitude.
(type=(float, float)); lengths - lengths of the mesh on latitude and longitude.
(type=(int, int))

Returns:: sequence of stations loaded from specified file.
(type=sequence of Station)
