Dataset NameThe dataset names for all EUMETSAT instruments follows the same basic format. <INSTRUMENT_ID>_<PRODUCT_TYPE>_<PROCESSING_LEVEL>_<SPACECRAFT_ID>_ PRODUCT_TYPE - 3 characters defining the type of product (For ASCAT this indicates the resolution - SZF (full), SZR (research - 25KM), SZO (operational 50 KM); for all other instruments: xxx (literally 3 lower case x's) ) PROCESSING_LEVEL - 2 characters (1B for ASCAT, GOME, GRAS; 1C for IASI) SPACECRAFT_IUD - 3 characters (M02, eventually also M01) SENSING_START UTC - 15 characters - 14 for the date, one for the "Z" at the end - (YYYYMMDDHHMMSSZ) SENSING_END UTC- 15 characters - 14 for the date, one for the "Z" at the end (YYYYMMDDHHMMSSZ) PROCESSING_MODE - 1 character (N (nominal), B (backlog), R (reprocessing), V (verification) ) DISPOSITION_MODE -1 characters (T (testing), O (operational), C (commissioning) ) PROCESSING_TIME UTC 15 characters - 14 for the date, one for the "Z" at the end (YYYYMMDDHHMMSSZ) SOME_DATE -14 characters (No Z at the end) (YYYYMMDDHHMMSS) Total length - 67 defined in documentation + 16 (2 underscores plus some date) = 83 characters |

UTCCoordinated Universal Time (UTC) is the international time standard. It is the current term for what was referred to as Greenwich Meridian Time (GMT). Zero (0) hours UTC is midnight in Greenwich England, which lies on the zero longitudinal meridian. Universal time is based on a 24 hour clock, therefore, afternoon hours such as 4 pm UTC are expressed as 16:00 UTC (sixteen hours, zero minutes). |
