| New technique for inverting truncated ionospheric RO from GNSS measurements |
| DATE: 2022-06-23 14:40 TYPE: DATA |
| Description |
| Dear ROM SAF Data user Issued: 2022-06-23 14:40 UTC We have developed a new technique for inverting truncated ionospheric RO from GNSS measurements for the future EUMETSAT EPS-SG mission. In this method, we compute the electron density values that fit in least mean squares in the Abel inversion of the available carrier-phase measurements in the EPS-SG illuminated region (impact parameter heights below 500 km). The upper contribution is estimated by enumeration of the possible values of the four parameter values that drive Chapman’s model under the assumption of vertical linearly increasing scale height. Please follow this link for more information about the method and how to access examples of retrieved electron density profiles: https://www.romsaf.org/previous_news.php#June23-22_174 Kind regards The ROM SAF Team |
