, variable_mapping=None, soil_mapping=None, depth_profile=[2.5, 5, 10, 15, 20, 30, 35, 50, 75, 100], include_missing_variables=False, **kwargs)[source]

Returns xarray.Dataset with stored data and metadata from a user-defined query of ARM-standard netCDF files from a single datastream. Has some procedures to ensure time is correctly fomatted in returned Dataset.

  • ds (xarray.Dataset) – Dataset of data to convert to AmeriFlux format

  • variable_mapping (dict) – Dictionary of variables mappings. The key should be the name of the variable in the Dataset with the values being dictionaries of the AmeriFlux name and units. For example:

    var_mapping = {

    ‘co2_flux’: {‘name’: ‘FC’, ‘units’: ‘umol/(m^2 s)’},


  • soil_mapping (dict) – Dictionary of soil variables mappings following the same formatting as variable_mapping. It is understood that the AmeriFlux name may be the same for some variables. This script attempts to automatically name these measurements. If a variable is not dimensioned by a depth nor has a sensor_height attribute, it will automatically assume that it’s at the first depth in the depth_profile variable.

  • depth_profile (list) – List of depths that the variables will be mapped to. If a depth is not in this list, the index chosen will be the one closest to the depth value.

  • include_missing_variables (boolean) – If there variables that are completely missing (-9999) chose whether or not to include them in the DataFrame.


df (pandas.DataFrame (or None)) – Returns a pandas dataframe for easy writing to csv
