Please be advised that the 4th ěrsted International Science Team meeting is planned to be held in Copenhagen, September 23-27, 2002. The meeting will bring together scientists and engineers working in the fields of high-precision space magnetometry and GPS occultation techniques.
The meeting will be an opportunity to discuss science and technical issues related to the ěrsted, SAC-C, and CHAMP missions, as well as the planning of future satellite systems.
More details will follow in the fall.
Geomagnetic Indices are provided on time scales, varying from real time estimates, through quick look (1-2 days after), half-monthly (e.g., Kp), preliminary, to definitive (often several years later - e.g., Dst). Increasing effort is being devoted to providing real-time services, but there is generally a trade-off between speed of deliverability and accuracy. We are also concerned as to whether the indices currently available really do meet user's needs (for example, 3 hour range indices such as the K and aa might be used when what is really needed is an index that is a direct measure of rapid transient variations).
In order to collect input on these issues, we have developed a questionnaire which may be found at the following link:
Could you please take a few minutes to complete this questionnaire? If you make multiple uses of indices, please submit a separate response for each use.
Thank you for your help - we are very grateful for any information you can contribute.
