fluxer package

Routines and tools to process flux (eddy covariance) data, as collected by CEOS.

Basic usage

The package currently has 2 sub-packages:

  • eddycov
  • underway

eddycov is the eddy covariance package, and underway is a package for calculation of pCO2 from an underway system. Each package can be imported individually as usual, e.g.:

import fluxer.eddycov as eddycov

Or

import fluxer.underway as underway

Project configuration

The easiest way to use the packages is to set up a configuration for any given project. The source for fluxer includes the default configuration settings required by each sub-package (under the config/ directory). These settings are specified in a *.cfg file (syntax instructions are given in the default files).

eddycov package

The main interface for this package is the function main:

# The main() function takes a configuration file and runs the analyses
import fluxer.eddycov as ec
ec.main("ec_config.cfg")

and there is also a command-line utility:

get_fluxes ec_config.cfg

underway package

This package offers two functions: main and underway_pCO2.

# The main() function takes a configuration file and runs the analyses
from fluxer import underway
underway.main("ec_config.cfg")

# The underway_pCO2() function takes an input data file and a *parsed*
# configuration file and runs the analysis for it
from fluxer import underway
from fluxer.flux_config import parse_config
config = parse_config("uw_config.cfg")
eddycov.underway_pCO2("YYYYMMDD_100000_20min.csv", config)

It is also possible to perform the analysis from the shell command line:

get_pCO2 ec_config.cfg
