level 1a Data
Level 1a data are generally data which are similar in content to level 0 (raw data), but which have undergone reformatting and splitting up into easier to process units.
The level 1a data specification is an important interface for COSMIC. This is the point past which we hope to keep all processing (nearly) the same for all missions. In other words, all mission specific processing should take place between level 0 and 1a, and level 1a should be as general and applicable to all missions as possible.
