Unfortunately, we won't be able to do anything for this flight. [GMT 08/27/05 15:16:06] Mike, let's hope the dropout does not happen often, then we don't need to reconnect. [GMT 08/27/05 15:16:22] Stacy- be advised radar system has been down since 1511, will advise when we come back online [GMT 08/27/05 15:16:34] thx brad [GMT 08/27/05 15:16:36] mblack-hrd (mblack@rdcc.guest.ucar.edu) joined &RAINEX. [GMT 08/27/05 15:16:49] brad: the slight rise in prssure is consistent with the eyewall replacement cycle [GMT 08/27/05 15:16:50] Cai-NRLP3: essentially, yes, but the exact problem is that the bandwidth is being used fully and the chat client and chat server's ability to communicate is being affected [GMT 08/27/05 15:16:56] Brad, LF or tail? [GMT 08/27/05 15:17:03] Indeed. Cai: Both. [GMT 08/27/05 15:17:30] We are orbiting until it's back up owing to Pilot's reliance on LF in place of nose display [GMT 08/27/05 15:17:48] Cai-NRLp3, fyi, there seems to be a correlation between your comm dropouts and failure of our images to be centered on your location. [GMT 08/27/05 15:18:24] Mike, as long as the image transfer is least affected, a longer reconnection time may be acceptable [GMT 08/27/05 15:19:39] nrl p3 is at ABOUT 29N 81W [GMT 08/27/05 15:19:44] Cai-NRLP3: that is the trade-off. We can work in boulder to reduce the bandwidth that the image transfer can use which will speed up chat reconnects, but then that will affect the speed of the image transfers. [GMT 08/27/05 15:20:08] Ops & NRL - Be advised that due to extra work in marking center, our arrival on E side will be delayed to 1615 or even 1630 [GMT 08/27/05 15:20:26] Stacy, when Iridium drops out for a while, you don't have our location info. May be that is the problem for the decorrelation. [GMT 08/27/05 15:21:01] Cai-NRLP3: Yes, that must be the problem. No point to center the image on. [GMT 08/27/05 15:21:55] right now the lf retrieval has been taking about 2 minutes [GMT 08/27/05 15:22:00] I suppose it could just use the last known good point in that case [GMT 08/27/05 15:22:26] Cai and Mike, as long as everyone is aware of the problem and it doesn't get worse, I think we can live with it. [GMT 08/27/05 15:22:36] ok. [GMT 08/27/05 15:23:46] Mike, the image seems to arrive within 3-5 min without the LF data. It will take longer with LF. So, I don't think reducing the image bandwidth is a good idea. [GMT 08/27/05 15:24:45] lf should be flowing from 43 now [GMT 08/27/05 15:24:53] Nick change: n43_RAMS_ -> terry-n43 [GMT 08/27/05 15:25:18] lf data is arriving in ops center [GMT 08/27/05 15:25:22] Ops - Be advised radar is just now coming back up. Rob estimates our arrival at E-most point in pattern (at which we would begin NW-bound curved downwind leg) is about 3 hrs from now, ca. 1815 [GMT 08/27/05 15:26:38] mblack-hrd (mblack@rdcc.guest.ucar.edu) left irc: Quit: This computer has gone to sleep [GMT 08/27/05 15:27:43] Stacy, if you look at the 15:12 image, the image is not centered on the NRL location. However, this suggests that you are using a very old postion for this image ( I mean computer used). [GMT 08/27/05 15:27:58] wen chau: are you aware that N43 is behind schedul and will arive at rendezvous at about 1815??

However if your sat link was down for 8 minutes, that might account for that very old position [GMT 08/27/05 15:30:13] Bob, yes, just got that from Brad. So we will do something by ourselves for about two hours. NRL should arrive IP about 1615. [GMT 08/27/05 15:31:32] Stacy, however, the track of NRL should not be presented on the image past that point. [GMT 08/27/05 15:32:01] Cai, unless the center is determined first and then some track info arrives before the plot... [GMT 08/27/05 15:32:15] deanna, wen: We can guide you using the Key West radar. We'll work up some way points [GMT 08/27/05 15:32:47] N43 still spiraling -not quite sure what the hold-up is [GMT 08/27/05 15:32:59] Stacy, yes, that make sense.

[GMT 08/27/05 15:34:22] stacy, the 15:32 image's positioning hasn't improved [GMT 08/27/05 15:34:42] plane's position isn't in the image anymore [GMT 08/27/05 15:34:55] Deanna, I've noted that . . . will continue to monitor the situation [GMT 08/27/05 15:34:55] Resuming track 225 [GMT 08/27/05 15:35:12] ok [GMT 08/27/05 15:35:44] Cai-NRLP3: One thing we could try wrt chat reconnects and LF data xfer is to delay the *start* of LF image transfers once the irirdium reconnects. This would allow the chat clients to reconnect more quickly, but would not affect the rest of the image transfers. We would want to make sure that it doesn't mean that we would have a backlog of images that need to be sent, though.

We woudl have been hard-pressed to set up the pattern you did given our zoomed-in LF radar [GMT 08/27/05 19:04:23] Another very interesting RAINEX target would be the "new" outer eyewall... tho not so practical from NRL's perpsective [GMT 08/27/05 19:04:51] Picking our way through lumpy convection on our way back to Figure-4 pattern [GMT 08/27/05 19:05:27] yes, the outer eyewall is healthy!

[GMT 08/27/05 20:56:35] Brad, do you see a big hole on your LF data surrounding your plane (something like 50 km radius roughly? [GMT 08/27/05 20:59:41] Brad, is it possible that 43 is flying in clear region and all we see now is sea clutter at long range. [GMT 08/27/05 20:59:52] we're done....heading to mcdill [GMT 08/27/05 20:59:55] Yes. I can explain it to you later. Who is asking the question? [GMT 08/27/05 21:00:13] 43 will be on-deck at 2110, barring weather delays into MCF [GMT 08/27/05 21:00:16] it's wen-chau [GMT 08/27/05 21:00:19] Wen [GMT 08/27/05 21:00:53] Sure Wen-chau. Basic principle is this: LF beam is a fan beam, spreading vertically up (but more importantly *down*) from aircraft with range. [GMT 08/27/05 21:01:23] So it approximates a cone. And because of our altitude, the beam strikes the surface beyone a certain range. [GMT 08/27/05 21:02:18] Essentiallyo it's a problem in conic sections--the intersection of a cone (our beam) and a plane (the earth's surface). It results in some strange artifacts. [GMT 08/27/05 21:02:33] Including the appearance of a parabola-shaped return when we are in steep turns. [GMT 08/27/05 21:02:38] Does that explanation help? [GMT 08/27/05 21:02:49] Brad, that is important for me to get used to. That is another reason 43 cannot be too far away from NRL in formation. [GMT 08/27/05 21:03:11] Is there any sign of the inner eyewall collapsing and is the wind max at the outer? [GMT 08/27/05 21:03:19] Yes Wen-Chau... there are *many* peculiarities of LF data--it's literally taken me years to get used to it. [GMT 08/27/05 21:03:48] Mike - we saw double wind maxima, with the outer band generally having the stronger one (at least on our final trip out through the NE quadrant) [GMT 08/27/05 21:04:00] Brad, I saw the pattern when NOAA P3 turns, but have not experienced sea clutter on LF before. [GMT 08/27/05 21:04:08] Crossing the skyway bridge--we'll be on-deck shortly [GMT 08/27/05 21:05:06] Lots of people can imis-interpret LF. I got asked question early in flight if we were sector scanning LF (which I have never seen done), and it was merely the result of being in a steep/continuous banking turn as we orbited, yielding a parabolic (sector-shaped) echo return from intersection of beam with ocean surface [GMT 08/27/05 21:05:18] And that's your enviro-minute ;-) [GMT 08/27/05 21:06:32] ops, we are only about 25 mins out of tampa [GMT 08/27/05 21:06:52] Anyway Wen, the main thing is to think of LF scans not as a disk, but as a fan (or if one considers only the lower edge of the scan, a cone) [GMT 08/27/05 21:07:10] Brad- can you get YESTERDAYS drops from SED or Barry? [GMT 08/27/05 21:07:33] do we have a time set yet for the debrief conf call? [GMT 08/27/05 21:07:54] Ummmm, we didn't fly yesterday. And Stacy already has the ones from our MIA-landfall flight [GMT 08/27/05 21:08:08] high res D files? [GMT 08/27/05 21:08:11] Brad, hard to imaging 43 is not inside a hurricane. That threw me off for a while. [GMT 08/27/05 21:08:38] she has all of them , I believe. In fact she was asking me last night what all the various files off the CD meant and I referred her to *you*. Surprised she didn't ask you. [GMT 08/27/05 21:08:50] she hasn't shared [GMT 08/27/05 21:08:52] But if something got left behind, call me and I'll get it for you.
