The overall purpose of the ACCURAID project was an initial assessment of the scientific utility and performance of the novel LEO-LEO infrared occultation (LIO) part of the ACCURATE (Atmospheric Climate and Chemistry in the UTLS Region And climate Trends Explorer) mission concept. With regard to the GNSS-LEO and the LEO-LEO radio occultation parts (GRO and LRO), no work was done within this project, because measurement process and data-retrieval performance of these parts have been studied to some detail in previous work and are continued elsewhere.

ACCURAID was a preparatory and accompanying study in the context of the ACCURATE mission development. In particular, two main lines of work have been pursued:

  •     Enhancement of an existing end-to-end radio occultation simulation tool (EGOPS) for enabling quasi-realistic simulations of LIO measurements,
  •     Initial end-to-end analysis of retrieval performance for greenhouse gas and isotope profile retrievals from LIO data.

Project reports for both lines of work document the project results. ACCURAID’s initial activities on the ACCURATE mission concept are continued in the successor project EOPSCLIM and other projects.
