Atmospheric trace-gas inversion example dataset (Methane in the UK and Ireland 2014)

These data are required to reproduce the results in the paper titled Spatio-temporal bivariate statistical models for atmospheric trace-gas inversion by Zammit-Mangion et al., which has been accepted for publication in the journal Chemometrics and Intelligent Laboratory Systems in early 2016. The ZIP file contains many files that need to be placed in a "../data/" folder as described on the project software homepage here.

Contents:

The ZIP file contains many files

  • CH4_emissions_scaled_natural: This contains the emissions inventory used
  • UK_gridcells.txt: Indices on emissions map that correspond to sea/land UK territory
  • Ireland_gridcells.txt: Indices on emissions map that correspond to sea/land Irish territory
  • MHD_model_date.txt: NAME model output (source-receptor relationship) for a given month/year at Mace Head (MHD)
  • RGL_model_date.txt: NAME model output (source-receptor relationship) for a given month/year at Ridge Hill (RGL)
  • TAC_model_date.txt: NAME model output (source-receptor relationship) for a given month/year at Tacolneston (TCL)
  • TTA_model_date.txt: NAME model output (source-receptor relationship) for a given month/year at Angus (TTA)
  • MHD_obs_date.txt: Methane mole-fraction observations for a given month/year at Mace Head (MHD)
  • RGL_obs_date.txt: Methane mole-fraction observations for a given month/year at Ridge Hill (RGL)
  • TAC_obs_date.txt: Methane mole-fraction observations for a given month/year at Tacolneston (TAC)
  • TTA_obs_date.txt: Methane mole-fraction observations for a given month/year at Angus (TTA)
  • xxx_obs_date_filtered.txt: As above but with suspect mole fractions filtered out as described in the paper

Acknowledgments and disclaimer:

These measurements were funded by the UK's Department of Energy and Climate Change and partly by NASA funding for the Advanced Global Atmospheric Gases Experiment. This data was accessed on 25 Jul 2014 and is subject to change. Any use of this data for other studies should first be downloaded directly from the EBAS repository (http://ebas.nilu.no) to ensure that the most up-to-date data is used. Data inquiries or permission for use of this data should be directed to Prof Simon O’Doherty, University of Bristol (S.ODoherty@bristol.ac.uk). Model output was generated by the UK Met Office NAME model 3 version 6.3 (Jones, et al., 2007, http://www.metoffice.gov.uk/research/modelling-systems/dispersion-model). UK inventory estimates of methane emissions were provided by the UK's National Atmospheric Emissions Inventory for 2012, which can be downloaded at http://naei.defra.gov.uk.
