| Publication of ROM SAF Report 30 on single and dual frequency variational retrieval |
| DATE: 2018-04-03 12:10 TYPE: ROPP |
| Description |
| Dear ROM SAF ROPP User Issued : 2018-04-03 12:09 UTC A first look at the feasibility of assimilating single and dual frequency bending angles Report link: http://www.romsaf.org/general-documents/rsr/rsr_30.pdf Abstract: The report describes the results of some numerical experiments designed to investigate the feasibility of carrying out 1D variational retrievals using dual or single frequency radio occultation bending angles, rather than the usual ionospherically corrected ‘neutral’ bending angles. A detailed analysis of the results of carrying out these experiments on two example radio occultation profiles is followed by a statistical analysis of the results of doing so on 3500 consecutive profiles observed by the GRAS instrument on Metop-A. The retrieved ionospheric parameters are briefly reviewed. Further work is suggested. Kind regards The ROM SAF Team |
