CPD2 Variables by Instrument
In most cases full variable names is constructed by appending the instrument code after an underscore from the base name. That is a variable of “Q” on the instrument “A11” becomes “Q_A11” in the data. There are exceptions for instruments that log components that are not part of the logical instrument logger. For example the uMAC “X1” may log the variable “T_V11” in the “X1a” record.
A record is constructed in a similar fashion. Flags are documented here. Default record contents are listed. Internally data is maintained in the CPD2 data format.
Aethalometer
[1-7] designates a single digit within the range. For example “X[1-7]c” becomes “X1c” for the concentration at the first channel. The default wavelengths for each channel are:
- 370
- 470
- 520
- 590
- 660
- 880
- 950
Note that the actual wavelength does not affect data logging by the CPD(2) system in any way, these are provided only for ease of interpretation.

Generated CPD2 Variables
There are variables that are generated by various parts of the system that are not logged by a physical instrument or are not logged by the CPD2 data logger itself (for example weather data being imported).
Intensives Record
There are two forms of the intensives records: short (“s”) and long (“l”). The long version contains all the variables in the short version plus additional ones. Both are generated by data.aggregate.intensives. Note that the extensive parameters in this record are the same as those in the appropriate instrument record except for wavelength adjustments (to 450, 550 and 700 nm by default) as needed. Not all variables are available in one-minute data (humidograph and CCN fits for example). The XI record uses data from A11 (primary absorption) and the XJ record uses A12 (e.x. a CLAP running in parallel).

Variable Modifiers
Under certain conditions (averaging and/or cut size splitting) variables may be derived from other variables. Generally these are denoted by the original name plus a modifier. These modifiers take the form of additional characters in the “prefix” of the variable. Some common modifiers follow:
* “0” - PM10 cut size split. * “1” - PM1 cut size split. * “N” - Counts, usually the number of points in an average. * “g” - Standard deviation, usually of all the points in an average.
For example during averaging the variable “BsG_S11” (reference neph scattering) will have all the PM10 data placed into “BsG0_S11” while the PM1 data would be in “BsG1_S11”. Similarly it might have the number of points of the PM10 average in “BsG0N_S11” and the standard deviation as “BsG0g_S11”.
