da.calc.radiation

This is the calibration performed on the inputs to generate the radiation intensity.

Default: Division

The possible values are:

This is case temperature used for pyrgeometer corrections.

Default: Automatically selected

This is the dome temperature correction factor. This is applied to the difference of the case and dome temperatures each to the fourth, before the Stefan–Boltzmann constant.

Default: Disabled

This is dome temperature used for pyrgeometer corrections.

Default: Automatically selected

This is the E factor used for case temperature correction. This is applied to the case temperature before the Stefan–Boltzmann constant.

Default: 1

This is the calibration factor applied to the input. This factor should convert the input sensor reading to W/m².

This is the input sensor reading. This option is mutually exclusive with with instrument specification.

Default: All radiation voltages

These are the instrument suffixes to calculate temperatures for. This option is mutually exclusive with manual variable specification.

Default: All radiation instruments

This is output radiation intensity. This option is mutually exclusive with with instrument specification.

This is the Stefan–Boltzmann constant used.

Default: 5.670374419E-8 W/m²K⁴

This argument is used to specify the station used to look up variables that do not include a station as part of an archive read specification. The station is the three letter GAW station code of the location, such as BND. The argument accepts multiple stations specified as regular expressions and separated by : or ; or ,. For example BND,MLO and (BND|MLO) are two ways of selecting both the BND and MLO stations.

The special value allstations may also be specified to select all stations.

This argument may be split into multiple actual program arguments. Each part consists of one or more variable specifications separated by , (commas). The station and archive used if none are explicitly given are defined in the other arguments or inferred from system defaults. For example simply BsB_S11 selects the blue scattering from the S11 instrument and returns all cut sizes and metadata. If instead ::BsB_S11:pm10 is used then only PM10 scattering is returned. That is, the selection specifies "any" station and archive (the defaults are set in the other arguments) then requires that it has the "PM10" flavor. A specification such as bnd:BsB_S11,thd:BsB_S11 allows for data selection from multiple stations.

This may also be used to select a "record" type alias such as "S11a". In this mode all the variables defined in the alias are returned.

Finally the special value everything can be used to select all available data for the given station(s) and archive(s).

This argument may be split into multiple actual program arguments. This full list of time arguments defines a time bounds list that sets the range of data queried. The final resulting data are clipped to the given time bounds but any values that intersect them are returned.

This argument is used to specify the archive used to look up variables that do not include an archive as part of an archive read specification. The archive is the internal name, such as raw or clean_meta. The argument accepts multiple archives specified as regular expressions and separated by : or ; or ,. For example raw(_meta)? selects both the raw and raw_meta archives.

The special value allarchives may also be used to select all available archives.

This argument is used to specify the the file to read data from. If it is present and exists then data is read from the given file name instead of from standard input. Alternatively - (a single dash) may be used to explicitly specify standard input.
