2009 TCCON Data Release Auxiliary Files
No full textThe Total Carbon Column Observing Network (TCCON) is a network of ground-based Fourier Transform Spectrometers that record direct solar absorption spectra of the atmosphere in the near-infrared. From these spectra, accurate and precise column-averaged abundances of atmospheric constituents including CO2, CH4, N2O, HF, CO, H2O, and HDO, are retrieved.

TCCON/py-ginput – v1.1.8
No full textAnother minor update to address issues arising from running with GEOS IT.
Download URLs for GEOS IT updated to latest product.
Solves an issue running the satellite interface (oco, gosat, or geocarb subcommands)
with 3 GEOS IT input. The interpolators created for the GEOS IT files are large enough that
three cannot be passed between threads in Python 3.6 due to a limit on the number of bytes
that the Python 3.6 multiprocessing module can pickle. This is fixed by Python 3.10 at the
latest, but getting Python 3.10 and required numerical dependencies to reproduce the Python
3.6 results to numerical precision was not possible. Therefore, as a workaround, if the
satellite interface detects that it is running on Python 3.9 or earlier, it will pickle the
interpolators as separate files and load them back in from the threads when --nprocs is not
0.
There are two other aspects to this release:
This is the first release that can be run on Python 3.10 and has the changes needed to run
the satellite interface with GEOS IT files. v1.1.7 didn't have those GEOS IT changes and
v1.1.5d was not compatible with Python 3.6.
The unit testing code now ignores the GINPUT_VERSION value in the .vmr file headers; this
saves us from needing to update the test input files with each version if there should not
be changes in the output.Public repository for the GINPUT priors generato
TCCON/py-ginput – ginput v1.2.0 release
No full textThis release fully handles generating priors from GEOS IT met and chemistry data. Specific changes:
Tropospheric scaling for CO set to 1 (i.e. no scaling) when using GEOS IT chemistry files
A new module, ginput.priors.automation, and the corresponding subcommand (auto) constructed as an interface for a system that automatically runs ginput.
Functions to get information about the most recent commit for logging/file metadata have been updated to work with Git and Mercurial.
More flexibility to print download URLs for met files to stdout instead of to a file
New subprogram, getnoaa, to update the NOAA data used as input (pull request #6 by rocheseb).
Additional catch to handle missing udunits2 system dependency when importing the writers module (pull request #8 by chris-msat).Public repository for the GINPUT priors generato
TCCON/py-ginput – ginput v1.2.0 release – ginput v1.3.0 release
No full textThis release primarily adds two new features:
the ability to calculate a time-varying O2 mole fraction, which gets added to the .vmr file header.
better tracking of input met model data in the .mod file header.
To support the time-varying O2 mole fraction, it includes a new program that downloads Scripps O2/N2 data and NOAA global average CO2 data and calculates the yearly O2 mole fraction from them. This file is not included with ginput, but can be obtained by running the update_fo2 subcommand of run_ginput.py.
Other changes:
Some type hints in get_NOAA_flask_data updated to be backwards compatible to at least
Python 3.7.
Small update to mod_maker to handle taking chemistry variables from a different version
of the GEOS files than the met variables. This will support possible TCCON reprocessing
with GEOS FP-IT met and GEOS IT CO
TCCON/py-ginput – ginput v1.2.0 release – ginput v1.3.1 release
No full textThis release improves the ergonomics of including the time-varying O2 mole fraction by providing an option to the O2MeanMoleFractionRecord and a command line flag for the vmr and rlvmr subcommands to automatically download the necessary data and create/update the O2 mole fraction data file when creating .vmr files
