Jason-1 Altimeter Interim Geophysical Data Record (IGDR)
(JASON-1_IGDR)| DOI | |
| Short Name | JASON-1_IGDR |
| Description | The Jason-1 Interim Geophysical Data Record (IGDR) contain full accuracy altimeter data, with the exception of an interim orbit (accuracy less than 4 cm), provided within 3 days of data collection. The instruments on Jason-1 make direct observations of the following quantities: altimeter range, significant wave height, ocean radar backscatter cross-section (a measure of wind speed), ionospheric electron content (derived by a simple formula), tropospheric water content, and position relative to the GPS satellite constellation. The IGDR contain all relevant corrections needed to calculate the sea surface height. Sea surface height anomaly calculation and the recommended data editing criteria are specified in the Jason-1 I/GDR User Handbook. Since the IGDR is an interim product it is not validated, for the most accurate data available from the project use the GDR which has a 6 week time lag. |
