Settled Science

The science, it appears, is settled: raw climate station data should be available for all comers.

The Royal Statistical Society:
4. The RSS believes that the debate on global warming is best served by having the models used and the data on which they are based in the public domain. Where such information is publicly available it is possible independently to verify results. The ability to verify models using publicly available data is regarded as being of much greater importance than the specific content of email exchanges between researchers.

The Royal Society of Chemistry:
7. It is also imperative that scientific information is made available to the wider community for scrutiny: the validity and essence of research relies upon its ability to stand up to review. In fact, advances in science frequently occur when the prevailing view is challenged by informed scepticism, this is fundamental to the scientific method and should be encouraged, even if controversial. The RSC firmly believes that the benefits of scientific data being made available and thus open to scrutiny outweigh the perceived risks. To this end, scientific information should be made available on request as outlined in the Freedom of Information Act. Furthermore, research needs to be presented in an accurate and reliable manner in the correct context in order to optimise this process. It may also be necessary to incorporate an independent auditing system into peer review with the ability to demand access to raw data sets to ensure best practices are being adhered to.

The Institute of Physics:
8. As a step towards restoring confidence in the scientific process and to provide greater transparency in future, the editorial boards of scientific journals should work towards setting down requirements for open electronic data archiving by authors, to coincide with publication. Expert input (from journal boards) would be needed to determine the category of data that would be archived. Much 'raw' data requires calibration and processing through interpretive codes at various levels.

9. Where the nature of the study precludes direct replication by experiment, as in the case of time-dependent field measurements, it is important that the requirements include access to all the original raw data and its provenance, together with the criteria used for, and effects of, any subsequent selections, omissions or adjustments. The details of any statistical procedures, necessary for the independent testing and replication, should also be included. In parallel, consideration should be given to the requirements for minimum disclosure in relation to computer modelling.
The Institute of Physics also was scathing about CRU's behaviour.

I've seen strong criticism of the various centres' handling of urban heat sink effects; without full disclosure of data from all sites, it's impossible for the external observer to tell whether these sites are cherry-picked by the anti-warming folks or whether they point to more systematic problems.
