Climate data file

There are several options to import climate data.
The value -999.9 indicates that a measurement value is not available.

Mandatory extension: .cli

1. Version

Data file starts without any mandatory leading line. Description lines of optional number are possible and have to start with ! as the first character.
Following data lines contain daily values of meteorological data and are compiled as follows:

Position	description	unit
1	date as dd.mm.jjjj	-
2	mean air temperature	°C
3	relative humidity	%
4	precipitation	mm
5	atmospheric pressure	hPa
6	global radiation	J/cm²
7	wind speed	m/s

Examples for climate data set *.cli without any mandatory leading line

2. Version

First line of data file starts with N. After the first line description lines of optional number are possible and have to start with ! as the first character.
Following data lines contain daily values of meteorological data and are compiled as follows:

Date is given without any point

Position	description	unit
1	day	-
2	month	-
3	year	-
4	mean air temperature	°C
5	relative humidity	%
6	precipitation	mm
7	atmospheric pressure	hPa
8	global radiation	J/cm²
9	wind speed	m/s

Examples for climate data set *.cli with leading line starting with N

3. Version

First line of data file starts with T. After the first line description lines of optional number are possible and have to start with ! as the first character.
Following data lines contain daily values of meteorological data and in addition to 1.version maximum and minimum air temperature. The data lines are compiled as follows:

Position	description	unit
1	date as dd.mm.jjjj	-
2	mean air temperature	°C
3	relative humidity	%
4	precipitation	mm
5	atmospheric pressure	hPa
6	global radiation	J/cm²
7	wind speed	m/s
8	maximum air temperature	°C
9	minimum air temperature	°C

Examples for climate data set *.cli with leading line starting with T

Mandatory extension: .txt

First line of data file starts with any line and is being read over.
Following data lines contain daily values of eight meteorological data and are compiled as follows:

Date is given in another order

Only one line with any description is mandatory.

Position	description	unit
1	year (jjjj)	-
2	month	-
3	day	-
4	maximum air temperature	°C
5	mean air temperature	°C
6	minimum air temperature	°C
7	precipitation	mm
8	relative humidity	%
9	athmospheric pressure	hPa
10	global radiation	J/cm²
11	wind speed	m/s

Examples for climate data set *.txt

Recommended extension: .dat

The extension of the filename is arbitrary, but different from cli and txt. The data can start immediately or with a heading line starting with ta.
The data lines contain daily values of eleven meteorological data and are compiled as follows:

Date is given without any point

No description line is allowed.

Position	description	unit
1	day	-
2	month	-
3	year	-
4	maximum air temperature	°C
5	mean air temperature	°C
6	minimum air temperature	°C
7	precipitation	mm
8	relative humidity	%
9	atmospheric pressure	hPa
10	vapour pressure	hPa
11	sunshine duration	h
12	cloud coverage	eighth
13	global radiation	J/cm²
14	wind speed	m/s

Examples for climate data set *.dat

Already intended is the adoption of a weather generator for the data with monthly temporal resolution.
