METHANE+

Netherlands Institute for Space Research (NWO-I SRON) (NL)

Summary

The ESA Methane+ project aims at exploiting the SWIR and TIR CH4 observations from different satellites in order to better differentiate between sources and sinks of CH4 on the regional and global scale. For this we will use the CH4 observations of TROPOMI on Copernicus Sentinel-5p, IASI on MetOp-B, and CrIS on Suomi NPP in combination with atmospheric inversion models.

OBJECTIVES:

Given the identified opportunities and challenges of the current generation of space borne methane sensors, and the scope of the current study, the specific study objectives are as follows:

  • Providing support for the algorithm development for the CH4 SWIR retrieval from TROPOMI, TIR from IASI/CrIS, and joint SWIR-TIR retrieval from TROPOMI and IASI/CrIS.
  • Assess the quality of the TROPOMI, IASI and CrIS CH4 retrievals by comparing data products generated with different algorithms and product validation using independent ”ground-based” measurements.
  • Investigate the added value of combining CH4 SWIR and TIR in regional case studies.
  • Infer global sources and sinks of CH4 from inverse modelling of 2 years of TROPOMI and IASI (and/or CrIS) data.
  • Investigate the added value of the combined use of SWIR and TIR CH4 observations.
  • Investigate the consistency of the SWIR and TIR CH4 satellite data, with model simulated transport and chemistry.
  • Formulate a road map for future CH4 satellite remote sensing based on the outcomes of this study as well as parallel studies covering the use of CH4 from TROPOMI across the full range of scales.

The Methane+ project started on 22-Jan-2020 with a duration of 2 years.
