This provides a way to reduce the amount of smr files. |
This provides a way not to change your default summary beams. |
You need at least QNX 4.24 or 4.25 for QNX OS to be Y2K compliant (The latest version is QNX 4.25C as of Jan.12, 2000), and you need Radops2000 version 4.10A to create SuperDARN Y2K data file names!!! **************************************************************************** |
Get BasyouhuC200005 ver.1.00 installation package from http://www.uap.nipr.ac.jp/SD/BasyouhuC200005/ (here!) The installation package file you should get is BasyouhuC200005.tar.gz (check if the size is 39285 bytes & cksum = 909610295 on QNX) (You can get this by clicking it durin pressing 'shift' key, hopefully...) (If you cannot get/save it, please try the following... Install packages to choose one.) Put it on your Radops QNX PC. (Be sure the file name shuold be "BasyouhuC200005.tar.gz" or "BasyouhuC200005.tar.F". If it's not so (e.g. BasyouhuC200005_tar.gz, BasyouhuC200005.tgz), rename it after transfering it to QNX...) (If you use older QNX (earlier than v4.24) whose "install" program does not support gzipped packages, first you should uncompress it by gunzip, and then freeze it by doing "freeze -v BasyouhuC200005.tar" to create "BasyouhuC200005.tar.F" before going ahead...) (Or you can get "BasyouhuC200005.tar" or "BasyouhuC200005.tar.F" directly from this web. Press "Install packages" above.) (If you don't have gzip/gunzip on QNX, you can get it from Quics! Press here to get "gzip.tar.F"!) Do the following on your Radops QNX PC. install -u BasyouhuC200005.tar.gz (If you get or create "BasyouhuC200005.tar.F", do instead like... install -u BasyouhuC200005.tar.F ) and follow the setup instruction to complete the installation process... (Julian, now you can install it in any directory you like...:-) This should work for Radops2000 version 4.01, 4,10 and 4.10A on QNX 4.22A, QNX 4.24, QNX 4.25/4.25A/4.25B/4.25C, I hope. *** CAUTION ***************************************************************** You need at least QNX 4.24 or 4.25 for QNX OS to be Y2K compliant, and you need Radops2000 version 4.10A to create SuperDARN Y2K data file names!!!! ***************************************************************************** If you encounter any problem, please let me know it as soon as possible. PS. You can also see source codes here on this web. BasyouhuC200005.c BasyouhuC200005.h makefile report2.c sync2.h ntp.h forbid_freq_check.h option2.h show.h freq_band.h pulse_code.h
2. Schedule file
Add the following entries to your schedule file for May, 2000 manually! (We strongly recommend you use this file to create your schedule file!!! to avoid any unexpected mistyping!!!) (The same documentation as this is included in the installation package. Its file name is "00Readme" found in the source directory where you install. You can use it to create your schedule file (and you can also aviod any unexpected mistyping!!!). For May DT,... ............. # May 3 Discretionary Time 2000 5 3 0 0 /radops/usr/bin/BasyouhuC200005D -df xxx -nf yyy ............. where... xxx : day-time start_freq/band (in kHz) yyy : night-time start_freq/band (in kHz) Please specify these 2 best frequencies!!!!!!!!!!!!!!!!!!!! to get as much ionospheric echo as possible!!!!!!!!!!!!!!!!!!!! (Please avoid your restrict freq bands, of cource...) * Default intt is 3 seconds. If intt=4sec is much much better than intt=3sec to get much more echoes, please don't hesitate to change it by '-it' option... * If you want to reduce the amount of smr files, you can specify '-smrsep smrsepsec' option. 'smrsepsec' is miminum separation in seconds bewteen the last recording time and the next recording time for each smr beam. (The default value is just 0(L)(second).) E.g. BasyouhuC200005 -df xxx -nf yyy -smrsep 60 if you want to record smr files only once per minute for each beam to reduce the amount of smr files. * If you don't wanna change your default summary beams (which are SMR_BEAM_A and SMR_BEAM_B defined in your /radops/usr/include/default.h), just specify '-nosmrch' command line option. If you want sd_summary to record only 1 smr beam, make sure that SMR_BEAM_A is the one you want, and also SMR_BEAM_B is -1(not between 0 and 15). (But if you specify this -nosmrch option, * Even if you specify -nosmrch option, -smrsep option will also work now (for Julian). If you need more info, you can see the online usage of this RCP by doing use BasyouhuC200005 (|more) or read the source code or ask me...
3. Test running, please...
After reading the explanation of the sounding mode below, please run this RCP before the May. DT(May 3) if possible although only a few DT days left before them(or no days left...). Please test this RCP with the 2 options, -df and -nf at your radar site. (It's good enough for this RCP to run just for 10 to 15 min or so.) And please report any problem to me ASAP if any. Please make sure again that you specify '-df' and '-nf' options for your test run as describled above. You can see display task's display or 'errlog' file to check if intt is correct or not, and if beam sequence and freqency setting are correct or not. This RCP will output time/bmnum/start_freq/scan for each beam in errlog file ONLY IF you specify higher verbose level by '-v N' (N=2,3,4...) command line option to this RCP(default:N=1). Many thanks for your great efforts to check and run this RCP!!
4. Sounding mode
This BasyouhuC200005 is a modified version of Basyouhu scan which ran for our Special Time in Feb.,1998, Jan. to Aug., 1999, and Jan. to Mar., 2000. (If any of you cannot perform intt=3 on your radar, let me know soon.) For most radars for most days, various Basyouhu scans will be made to get (1 to) 3 high time resolution special camping beams data with optimized high time resolution global convection data simultaneously. intt=3sec,frang=180km,mpinc=2400,rsep=45km as usual, but no GPS synchronization. (If intt=4sec is much much better than intt=3sec to get much echoes, please don't hesitate to change it by -it option...) CP=5249 Detailed beam sequences for all the radars will be shown below...
5. Beam sequence
Each beam sequence for each radar is almost completely different from ones for the other modes/radars.

6. Notes
'vlptm' is now not good for any beam sequences which include camping beams. This is because vlptm regards any beams with scan!=0 as start_beam which means any special camping beam whose scan value is negative will be regarded as a start_beam and which is meaningless. If you change vlptm code a bit you might get much more proper vec files for some of special programs including Basyouhu... A line 277 in vlptm.c both in Radops2000 version 4.01 and version 4.10, if (scan && (bmbak != -1)) { .... shuold be modified to if ((scan==1) && (bmbak != -1)) { .... (or if ((scan>0) && (bmbak != -1)) { .... (this is my favorite...)). I strongly recommend you to adopt this fix to get proper vec files even when we do any other mode than normal_scan. (before grid files officially become used for the ISTP KP data or before next Radops is available.) How do Mike and Rob think about this?
7. SuperDARN time allocation request
sent to SD scheduling working group
> Date: Mon, 6 Mar 2000 17:50:56 +0900 > To: darn-swg > From: Natsuo Sato > Subject: NIPR SD request (May) Dear Catherine and Scheduling WG, Thanks for your arrangement of SuperDARN scheduling. I am attaching here the NIPR requests for Time Allocation in May. One request is the DT request, and the other is the operation period when High Time Common Mode will run. NIPR is planing that the same request will apply in June, July and August during austral winter season. Best regards, Natsuo ######################## # ==== Request -1 ==== # ######################## SUPERDARN TIME ALLOCATION REQUEST (from NIPR: No1) MONTH: May 2000 PERIOD (DATES, TIMES): 4 days requested. Best optical observing conditions at S. Pole, Zhongshan and AGOs in Antarctica are 1-9 and 27-31 May around new moon periods (new moon is 4 May and 2 June) Note that the same request will apply in June, July and August. RADARS: Syowa South, Syowa East, Kerguelen, Halley, Sanae and Tiger in the southern hemisphere and CUTLASS in the northern hemisphere. CLASS (Special time, Discretionary time): DISCRETIONARY INSTITUTE: NIPR/BAS/ Univ.Natal/CNRS/ La Trobe Univ./ Univ. Leicester PI: N. Sato SCIENTISTS: N. Sato, H. Yamagishi, A. S. Yukimatu, M. Watanabe, M. Pinnock, D. Walker, Jean-Paul Villain, Jean-Claude CERISIER, Peter L Dyson and Mark Lester COLLABORATORS (Outside of SD): M. Ejiri, S. Okano, M. Taguchi and M. Okada (NIPR; S. Pole Optical) + R. Liu & H. Yang (Chinese Polar Institute; Zhongshan Digisonde and Optical) + Antarctic AGO experimenters. PROGRAMME TITLE: Study on the radar and optical signatures of the dayside phenomena in the cusp region and their geomagnetic conjugacy SCIENTIFIC CASE: The field of view of Syowa South, Halley and Sanae radars cover over South Pole Station, where NIPR's and AGO's monochromatic all-sky auroral imagers are working. Syowa East and Kerguelen radars cover over Chinese Zhongshan Station, where NIPR's all-sky CCD camera (6300 or 5577 A), panchromatic all-sky camera and scanning photometers (6300, 5577 and 4278 A) and Chinese Digisonde are operating. Both of South Pole and Zhongshan are located at the cusp region (~75 degree), but about 6 hours different in MLT. The Tiger radar, which covers more equatorward and more different local time from other southern hemisphere SuperDARN radars, provides the relationship between dayside and nightside phenomena. Quasi-periodic (QP) variations of optical aurora are the outstanding characteristics in the dayside cusp region. The mechanism of such quasi-periodic variation is still an open question. The candidate mechanism would be MHD wave, FTE, plasma pressure pulse, etc. Simultaneous observations of optical aurora with monochromatic wavelength and radar aurora are very important method to solve this problem. Coordinated observations with HF radars in both hemispheres, all-sky imagers and digisonde at different local time would clarify the IMF dependence, propagation characteristics and local time dependence for such quasi-periodic phenomena. The observations from the conjugate regions (Syowa East-Kerguelen and CUTLASS over Zhongshan) are very valuable for this scientific aim; for example, the time difference between the two hemispheres in the response to an IMF Bz, By and Bx changes. EXPERIMENT OBJECTIVES: High time resolution velocity for one to three beams from each radar crossing over S. Pole, Zhongshan and AGOs and its conjugate region. Background flow conditions with full beam scans with higher time resolution. This operation enables us to compare the spatial and temporal variations between radar and optical auroras. REASONS FOR TIME PERIOD REQUESTED (Supporting campaigns, instrumentation, geophysical conditions): Optimum conditions for S. Pole, Zhongshan and AGOs optical observation during new moon periods (new moon in May is 4). COULD EXPERIMENT BE RUN AT ANOTHER TIME (YES/NO): NO (it is possible to shift within following period) No moon light interference periods are 1-10 and 27-31 May and a new moon is 4 May. Therefore the best period is the 4 days around 4 May. RADLANG PROGRAMMES TO BE RUN AND BRIEF DESCRIPTION OF SOUNDING MODE: All radars run one to three camping beam (high time resolution) with global scan. = END OF FORM = ######################################################### # ====== REQUEST-2 (Additional request from NIPR) ==== # ######################################################### SUPERDARN TIME ALLOCATION REQUEST (Additional request from NIPR) ** Though this is a Common mode allocation request, I (NIPR) want to arrange SWG to allocate the High Time Common Mode during the following period if it is possible **** MONTH: May 2000 PERIOD (DATES, TIMES): 4 days requested as High Time Resolution Common Mode (4 days period is a standard duration as HTR, in my understanding).

8. Explanation of sounding mode (2)
> Date: Wed, 19 Apr 2000 12:57:32 -0700 > From: Natsuo Sato > Subject: Summary of May DT Dear PIs of all of the Southern Hemisphere and CUTLASS radars, (M. Pinnock, D. Walker, Jean-Paul Villain, Jean-Claude CERISIER, Peter L Dyson and Mark Lester-sama) Thanks for your (Mike, Mark and Peter-san's) suggestion and approval about the proposal of NIPR May DT plan. In order to arrange the RCP by Sessai for this experiment soon, I want to summarize the plan in the followings. If you have comment and suggestion, please tell me as soon as possible. 1) Summary of the special beams at each station All radars run three camping beams with global scan. The special beam N at each station is as follows; Syowa East: N=7, N-2, and N+2 Syowa South: N=3, N-2, and N+2 Kerguelen: N=6, N-2, and N+2 Halley: N=3, N-2, and N+3 (!!) Sanae: N=5, N-2, and N+2 Tiger: N=7, N-2, and N+2 Iceland East: N=4, N-2, and N+2 Finland: N=4, N-2, and N+2 where N is the highest time resolution beam (may be 12-sec sampling time with 3-sec integration) which is directed over Zhongshan and South Pole or their conjugate point except Tiger. On the other hand, N-2/N+2 or N+3 are the beams with the second highest time resolution (24-sec sampling with 3-sec integration). 2) The RCP operates with Basyohu. 3) Priority for the usage for this DT data Each PIs of this collaboration is available to use own data immediately and freely, I believe. (As Mike-san pointed out, the SuperDARN agreement is a problem for such collaborative DT project. That is, the SD agreement says that the PI of the radar has sole use of DT period data for 4 years. But of course I am not the PI of other radars who has made the request for this DT period, for me!!). This issue may be discussed at coming SD workshop. Thanks for your collaboration. Best wishes, Natsuo
That's it. Many thanks in advance! Regards, Sessai
