That is a nice IR layer. I changed some of the overlays to auto update, but other than that kept it as is. Looks good, and thanks.

First cut at SST is done. I haven't added it to the link yet because I've got to run for a couple hours and want to debug/polish it up a bit. Parsing those gribbed RAW data files isn't difficult per se, but it does make you want to kill byte arrays. Look for it to automatically be added either tonight ir tomorrow morning when your link refreshes. Here's a screenshot of the Alpha...

Thanks. Appreciate the tip. I'm starting to get the hang of it. Unfortunately, I am now having fetching errors when the NHC tracks update. I'll figure it out yet with the help of you great people!

Again, thanks,
Lynn

Lynn,

You may be getting fetch errors because I'm working on it. I'm sorry about that. If the kml is bad on a refresh, it should be fixed by the next timed update (10 mins I think). At least tonight, and probably at certain times tmw, you may get this same error. Hopefully it will be worth the fetch errors once I quit editing it.

Thanks for letting me know. I thought it was my computer or something I was doing wrong. Keep up the great work!!!

Lynn

PS Is the Invest data missing because you are working on it as well?

The track models (including Invest) aren't put out by the NHC in the most reliable format. For instance.....the main reports that they put out are at 00Z, 06Z, 12Z, and 18Z. Four times per day, 6 hrs apart. Unfortunately, right now I only check for the latest one of those 4 reports. They also put out intermediate reports at say 01Z, 07Z, maybe 11Z, etc. . I'm not sure why they do this, other than the models for a particular storm may not be ready yet. In any case, the way I coded by client was the check for the very latest file by timestamp (the youngest file), the check to see if it one of the {00,06,12,18) set. If it isn't, then I check the next oldest file until I find one that falls into the (00,06,12,18) set so that I have the "official" report. The problem is that sometimes the official 6hr ones don't get updated with the proper information, they just put out one of those intermediate files. So to maybe make it a little more clear (I tend to ramble) here's a typical situation if say we are tracking 3 storms(2 invests, and 1 proper named):

00Z - Invest1, Invest2, Franklin
06Z - Invest2, Franklin
07Z - invest1
12Z - Invest1, Invest2, Franklin
18Z - Invest1, Invest2, Franklin
00Z - Invest1, Franklin
01Z - Invest2


So you can see that sometimes all of the storms aren't included in a single 6hr report. I will be working on this problem tomorrow. Odds are that if you're missing a storm that you think should be there, it will be there upon the next update.

On another note, I've upped the resolution of the SST overlays DRAMATICALLY and they look great now.....I'm going to try and get the Tropical Atlantic built into the feed tonight.

Regards,

Paul

Ok, the first cut at the SST data is now in the Network Link. If you just let the link refresh, the SST data should show up. It's very late, so there may be bugs, but I'm sure I'll hear from you if there are. You can see the improvement in resolution in the screenshot below when compared to the screenshot above. I did have some problems with GE complaining about the image format, but that just magically dissapeared....at least for me. Let me know.

Paul:

Thanks so much. I know there are quite a few of us at Storm2K (weather board) who are using this product and we really appreciate all the work you are puttiing into it! Great job.

No problem at all. I enjoy solving interesting problems. I'm looking for fairly high-res Visible, Infrared, and Water Vapor imagery now to add to this dataset. It'd be nice if it was geocoded or GRIBBed so that it fits nice and snug without hand fitting it. If anyone has any suggestions please let me know. Also, I do have the capability to easily add more sections of SST if anyone wants it.....I have the raw data for the entire globe, and I wrote a routine to generate bitmaps on the fly from input coordinates....so it's rather easy. Just let me know.

Very impressive! It is cool to see how you and pseabury collaborated to make layers that combine to present a very powerful image. Great work!
