lair.noaa.CarbonTrackerCO2#

class lair.noaa.CarbonTrackerCO2(version, carbon_tracker_directory=None, cache=True, grid='nam1x1', parallel_parse=True)[source]#

Bases: CarbonTracker

NOAA CarbonTracker (CO2)

Mole fractions are in ppm (micromol mol-1). Releases such as CT2019B keep the daily molefraction files flat in molefractions/co2_total/, one file per grid (CT2019B.molefrac_nam1x1_2015-06-01.nc, ..._glb3x2_...).

Parameters:

version (str)
grid (str)

grid#

The molefraction grid to read, e.g. 'nam1x1' (North America, 1x1 deg) or 'glb3x2' (global, 3x2 deg). Points outside the grid sample as NaN.

Type:: str

molefractions#

The molefractions Dataset.

Type:: xr.Dataset

units: Literal['ppb', 'ppm'] = 'ppm'#: Units of the molefraction field (‘ppb’ for CH4, ‘ppm’ for CO2)

property molefractions_dir: Path#: Directory of the total-CO2 molefraction files.

property molefractions: Dataset#: Molefractions Dataset on self.grid (lazy). Cached property.
