Notes
2314 Gadian § Output model runs not worth to be archived but ‘others may be interested in them’ (unclear)
§ 1 Gbyte=volume of output or input data? (unclear)
§ No data will be stored at BADC (unclear). Storage of model metadata.
§ Assistance in obtaining input data? Perhaps.

C-130 data should be kept complete and comprehensive in the long-term. Some information has been provided by Phil Brown (MRF), who is not one of the PIs and does not know for which project the data will be used. His info covers the data collected aboard the C-130 only.

Highly valuable data. Preserving and documenting both raw and final data for potential future use is essential. § Role of BADC essential in ensuring longevity of archive.
§ Possible contribution in retrieving new spectroscopic data sets as they appear in the future.

In the course of this project, data will be collected only to test the developed apparatus, they will have no scientific value. Raw data subsequently produced with the instrument by other groups should be archived. No BADC intervention required.
