Request for HARP ingestion update: GOSAT XCO₂/XCH₄ and OCO-3 V11 support

Thank you for maintaining and improving the HARP library. I would like to ask about two ingestion issues:

  1. GOSAT L2 products (GOSAT_FTS_L2_CO2_TC, GOSAT_FTS_L2_CH4_TC)
    Currently, HARP only ingests total column CO₂/CH₄ (CO2_column_number_density, CH4_column_number_density).
    However, most users are primarily interested in the bias-corrected column-averaged dry air mole fractions, i.e. XCO₂ and XCH₄.
    These variables are already present in the product files at:
  • Data/mixingRatio/XCO2BiasCorrected
  • Data/mixingRatio/XCH4BiasCorrected
    Would it be possible to update the ingestion module to expose these variables directly (similar to how OCO-2 ingestion provides XCO₂)?
  1. OCO-3 product versions (OCO_OCO3_LtCO2)
    HARP ingestion seems to support OCO-3 up to version V10.
    The current product version is V11, and V10 is no longer produced.
    Could you please add support for OCO-3 V11 in a future release? This would be very helpful, since new data are only available in V11.

These two updates would greatly improve the usability of HARP for the CO₂ community.

Thank you very much for your consideration.

Yes. We can implement this.
I can’t commit to a timeline yet, since it is a busy period. But it will come.
