Description
World Day planning session -- Workshop to discuss the proposed coordinated incoherent-scatter radar observations for 2011.
The URSI Incoherent Scatter Working Group (ISWG) will have its usual planning meeting at CEDAR to coordinate the World Day experiments involving the world's upper atmospheric observatories. The procedures for scheduling World Day observations are described at
http://www.eiscat.se/Members/ingemar/skedule/RequestingWD.htm
and the other links referenced therein which include a sample proposal.
Written proposals are requested for meeting specific research needs using the World Day observations. These proposals should be submitted by 5 June. The planning meeting is for the ISWG and UAF staffs to review all the proposals submitted and determine how the global network of ISRs can best satisfy the approved observational requests. The proposer's presence during this discussion is not required, but all are welcome, especially students.
Please feel free to consult with any facility staff member or the ISWG chair for clarification on the process for requesting ISR observing time within the World Day program.
Workshop Summary
Notes from the 2010 CEDAR workshop for 2011 World Day Planning
23 June 2010, 13:30 – 15:30, in Engineering 24, the University of Colorado at Boulder
The meeting was called to order by Ingemar Häggström, the chair of the URSI Commission G Incoherent Scatter Working Group.
Ingemar reported on the status of the schedule for the 2010 World Days – TID, Topside, StratWarm, and Synoptic. The StratWarm was an alert run, scheduled for 10-days if conditions were appropriate, and had a month-long window beginning in mid-January. This run was performed in response to the prediction of a sudden stratospheric warming event, and proved quite successful.
Ingemar then showed the two requests he had received for coordinated ISR runs in 2011, summarized here:
1) investigation of planetary-scale waves in the ionosphere during summer or fall a 10-day run in the summer of fall (minimum needed: 6 days) UAFs needed: Jicamarca, Arecibo and Millstone Hill proposed by Scott England, the University of California at Berkeley month desired, in order of priority: August, July, September, June
2) meteor flux during equinoxes two three-day runs during vernal and autumnal equinoxes proposed by Asta Pellinen-Wannberg, the Swedish Institute of Space Physics centered on 20 March and 23 September
There was general discussion about the need to know the productivity of the requestors (in any year) in order to ensure that publications will result from the coordinated operations of the ISRs. It was determined that this was not an obstacle for the 2011 requestors. The merits of both requests were discussed:
1) Planetary-scale waves: Winter data is not usable for Scott's study, and he was unaware of the month-long September 2005 world day runs and was pleased to hear about the availability of that dataset. There was some discussion about the fact that he does not need data from the high latitude ISRs and whether or not this should be viewed as a world day.
2) Meteor flux: There was some discussion about the large amount of data the ISRs will generate for the meteor experiment, as well as formatting issues. It was determined that two of the co-investigators (Ingemar Häggström and David Meisel) combined have worked with meteor data in the formats that will be used by the eight ISRs represented at the meeting.
Qian Wu, NCAR, requested ISR support for his HIWIND balloon-borne interferometer measurements, funded by NASA. His first request was for support by Arecibo and Millstone Hill in early September of this year – 48 hours during a test flight from New Mexico. His second request is for the high-latitude radars for up to five days of flight in June 2011. Both these campaigns would be on an alert basis with little notice. He would like ISR measurements of the F region to complement his own measurements of daytime thermospheric winds.
Since it is much too late to schedule a world day run of the low-latitude radars this September to support his test fight, he will request their support directly instead of as a world day.
Qian's requests resulted in a lot of discussion about the world day scheduling in general. Neither of his two requests are for all the ISRs. It was suggested that for his June 2011 request the ISRs could run in concert but for different purposes. For example, in June 2011, the low-latitude ISRs could run for Scott England's planetary-scale waves run while the high-latitude ISRs could support Qian's balloon campaign. But since the balloon support would be on short notice, this would not work well for the other sites (Arecibo in particular). Also arguing against this is that June is the fourth choice for the planetary-scale waves run.
There was some discussion about how many days should be granted to the requests, with the remainder of the world days filled with synoptic runs. John Holt reminded the group that the URSI Commission G mandate was for 19 days each year. Jan Sojka stressed the modelers' need for long runs.
It was decided to cut the meteor runs to two days each (instead of the requested three), making two two-day runs in March and September (four days total). The planetary-scale waves run was granted 10 days. [It was unclear to me if this was scheduled for June or not.] The data from the high-latitude radars, while not useful to Scott will be quite useful to the modeling community. The remainder will be filled with two three-day synoptic runs, bringing the total to 20 days. [Sorry, it's unclear to me if there were particular months for those two synoptic runs.]
