6.7. Definitive 1-Second Data
Since 2014 INTERMAGNET has requested observatories to provide 1-second definitive data if they are able to do so. Calls for 1-second definitive data will be made at the same time as calls for 1-minute definitive data. It is not a requirement of INTERMAGNET membership that an observatory is able to provide 1-second data. Where possible, observatories should produce data that complies with the INTERMAGNET 1-second data standard (see Chapter 3). At present observatories are requested to provide baseline corrected 1-second definitive data whether or not it conforms to the standard, though this is likely to change in the future as more observatories become able to meet the standard. INTERMAGNET is currently developing recommendations on how to produce 1-second definitive data that will conform to the standard.
INTERMAGNET has created a format for 1-second data (see APPENDIX E6) based on NASA’s Common Data Format (CDF) software. Observatories are asked to supply data in the new INTERMAGNET CDF format. Software for conversion to the new format is available. For the most up to date details of what software is available please see https://intermagnet.org/software.html
