Ten-Day Concatenated NWAC Telemetry

Nice work, guys. <br><br>Dkantola - your page comes as close as anything I've seen to the sorts of graphs I've imagined for plotting this data. Well done! Did you think about including the "24 hour snow" data? It would give a more graphically clear sense of how much snow has come down w/in a day. More minor comment - might be nice to have a colored bar at 32 degrees on the temperature plot. It would be kinda cool to be able to lay one graph on top of another (what was the wind doing when the snow was falling - it's visible on your page of course, but you have to scan to see this), but that's much harder from both a UI and coding standpoint and not worth the minor benefit.<br><br>Amar - Russ' comment was the first thing that came to my mind when I looked at your scraping, but it's pretty minor.

one suggestion is to display the concatenated data in reverse chronological order - just a personal preference....Thanks

<br>

I agree with Russ, reverse chronology is most helpful, if the code is easy and processing quick.

<br><br>Done. Data is now available in either normal or reverse chronological order.<br><br>I like dkantola's plots too, very nice. It would be great to be able to plot more than 21 days, though, in order to see the whole season's snow depth on a single plot. I've also been saving all the NWAC telemetry for this season and last, but I haven't decided what to do with it or whether to make it available online.<br><br>

Thanks for the comments. Today the plot and csv generator hasn't been working because the database server has been mysteriously crashing. I haven't been able to reproduce the problem, so I'll have to wait until it happens again to debug it.<br><br>

<br>I'm adding 24 hour snow data to the plots now. I could add a 32 degree line, but due to limitations of the program I'm using for plotting (ploticus), the line would appear outside the plot when the plot range doesn't include 32 degrees. This could be solved and arbitrary overlayed plots made possible if I were using templates to auto-generate ploticus scripts, which I might do it in the future. Right now the plot layouts are hand-written and pretty much static.<br><br>

<br>OK, I'll create new ploticus scripts for more than 21 days.<br><br>

<br>Please make it available in any form! I'd love to add it to my database.<br><br>

So nice that I wish I could have a larger version of each one.

<br>How large?

Amar and David - wow, nice work!<br><br>Having all 10 days of telemetry on one page is a major advance, and it makes me wonder why NWAC hasn't already done this. Amar, the adjustments you've made due to suggestions here are really good. I find the "reverse" listing to be the most useful - any interest in just making that the default display mode? I have some linking-to questions for you - I'll send in a PM.<br><br>David, the graphs are really useful! Am I reading the wind speed graph correctly - green is minimum wind speed, and top of blue shaded area is maximum? This makes it really easy to quickly see what was going on with the wind, especially combined with the wind direction graph just below.<br><br>I'm looking at the snow depth graph and wondering something. A few of the site graphs (eg. Snoqalmie Summit sites) have lines that really wiggle, making it harder to see the overall trend, but other site graphs have lines that are much smoother. Is this the data itself or are some of the graphs using some kind of running averaging to smooth the curves? I guess when the snow is really piling up and the y-axis has to encompass a bigger range the wiggles might be less prominent. Anyway, a minor concern but something I noticed.

<br>Green is average wind speed, the upper blue line is maximum, and the lower blue line is minimum, which is only available from some sites.<br><br>

<br>The snow depth data for many sites is low quality. I've tried to filter out as much obviously bad data as possible (seen as gaps in the plots), but what's left is what was recorded. Without filtering the plots would be full of spikes to 200-400 inches and unreadable.

Here is what I had come up with for myself and others to enjoy. I wrote a script to collect the numbers for each station into a database and then it dynamically generates a graph. I have it saving 3 months worth of data for each station and you can select as wide of a swath of time as you need. Though I would share it for all.<br><br>You will have to click the link and then naviage about half way down the page and 'Select a Station'. It also has a spot to check the weather and the current avalanche forecasts. Cheers<br><br> www.weekendclimber.com/index.php?option=...ap=Weather&Itemid=49
