- MARSSCRATCH:
The MARSSCRATCH is temporary development version of MARS database. Anybody can use it for the first preliminary tests but the data can disappear at any time even it is not happening most of the time.
Example of COSMO sample data stored in MARSSCRATCH: http://apps.ecmwf.int/mars-servers/marsscratch/?origin=edzw&stream=oper&class=ur&expver=test - MARS (expver=test)
Before the full production archiving (step 3) a few days of full UERRA data from given model are required to be archived in MARS with expver=test. It must be thoroughly checked that all fields are were archived as expected (no missing or additional ones; no missing or additional steps, levels etc.). The data archived as expver=test might be overwritten during this phase. - MARS (expver=prod)
Once all providers' processing and archiving scripts are verified as fully working during step 2, the production archiving can start. The production data in MARS might not be overwritten in the future as it is user data who can download them in any time so the step 2 has crucial importance. It is also very difficult to delete any unwanted data from production MARS e.g. archived by mistake so it should be avoided by all means. Only one user ID per provider is expected to have granted permissions for archiving in MARS to avoid any kind of possible double archiving in the same time etc.
