This component provides a parser and control to acquire data from a DMT CCN. This includes both offline parsing and online control.

Usage

da.acquire.dmt.ccn [switches…​] [file]

Switches

--mode=TYPE

This is the base import mode. It defines the defaults for other options. Thos defaults may be overridden by setting those options.

Default: Raw data

The possible values are:

--mode=cpd1

CPD1 raw data recorder output

--mode=cpd2

CPD2 raw data recorder output

--mode=doy

Same as --mode=twotime

--mode=raw

Raw data input, with implicit times

--mode=singletime

CSV input with a single time field

--mode=twotime

CSV input with a two part time field

--mode=yeardoy

Same as --mode=twotime

--basetime=TIME

When dealing with files without a full timestamp on each record, this time is used to reconstruct the full time from the time of day on the H records.

--model-interval=INTERVAL

This is the interval the model is executed at. This defines the amount of data averaged together to make a single request for the model to generate a supersaturation for.

Default: One minute

The interval must be greater than zero in length.

--processing-interval=INTERVAL

This is the interval the that general processing is executed at. This defines the amount of time that enters into the reported dT standard deviation.

Default: One minute

The interval must be greater than zero in length.

--record-index=INTEGER

The index, starting from one, of the record data.

This option only accepts integers greater than or equal to 1.

--stability=SMOOTHER

This is the smoother that is used to by the acquisition system to determine if T3-T1 is stable.

Default: Always stable

The smoother is used for stability and spike detection.

--station=STRING

The station code to assign to data values.

Default: NIL

--suffix=STRING

The instrument suffix (e.x. "S11") to use when completing variables.

Default: Automatically determined

--time-index=INTEGER

The index, starting from one, of the first (and only unless using multiple fields) time field in each record.

This option only accepts integers greater than or equal to 1. Undefined values are permitted, to indicate that the option is set but not to a specific value.

--time-index2=INTEGER

The index, starting from one, of the second time field.

This option only accepts integers greater than or equal to 1. Undefined values are permitted, to indicate that the option is set but not to a specific value.

Arguments

file

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.

If no file is supplied then the input is read from standard input.

Examples

Ingest CPD1 raw data record output
da.acquire.dmt.ccn --mode=cpd1
Discard the first field and ingest year and DOY times
da.acquire.dmt.ccn --mode=twotime --record-index=4 --time-index=2 --time-index2=3
Convert data
da.acquire.dmt.ccn
