In my case (CW0351), the gustiness looks to be proportionately too high as compared to the mean wind. You data and K3CHZ look much better. I don't have the climate statistics, but I was taught that the gusts will be about 80% greater than the mean wind in a mixed atmosphere (say between 09L and 15L). Things that will influence the gust to mean wind ratio will be siting/elevation AGL, time of day/mixing, anemometer resistence/spin-up drag, sensor reporting, data logger sample frequency and averaging. Tough to know for sure why different combinations to sensors, stations, and software result in different 2 minute mean wind and 10 minute gusts. Gerry Creager has proposed setting up a personal weather station testing facility to study these sorts of things, now all he has to do is find some $$$!

Particularly common was a type called Savonius Rotor. See: http://www.pcon-wind.de/grafik/g4.jpg This sensor was subject to errors in gust measurement due to mass of the spinning rotor, which took a time to spool up, and also continued to spin after a gust had ceased. Now, my bet is that the various ultrasonic sensors would provide a very high accuracy, but at a price. 73, DX, de Pat AA6EG aa6eg at hotmail.com; Skype: Sparky599 Moon or Bust!--Jamesburg Gang Rides Again! >From: "Mark Wyman" >Reply-To: Discussion of weather data quality >issues >To: "'Discussion of weather data quality >issues'" >Subject: Re: [wxqc] Wind gust averaging >Date: Thu, 1 Feb 2007 14:20:35 -0500 > >To me it looks like you gauge is properly sited high and away from >obstacles, where the others are not.

Chicago may be windy, but so are all cities!). Most of the time, the gust ratio will be smaller when considering shorter time intervals (e.g. 10 minutes). My add 80% to the predicted mean wind rule was a cover-my-rear estimate for peak winds and the stuff that came with that (mostly excessive cross winds for aircraft landing). Of course, I would forecast for 6 hour periods in most cases. Most statistic we have are using mechanical cup anemometers. The new sonic anemometers will have greater gust ratios (higher peak winds) since they do not have the spin-up lag problem.

My eyeball average says your gusts are around 75% more than your steady wind. The same eyeball average of my data says that my gusts are only 25% or so of my steady wind. It is interesting that if I look at my station on a 10 day time span, it looks like the gust/steady wind ratio is "about right". However if I look at the wind on a 12 hour time span, today for example, it looks like I have all wind and no gust, or at least many more reporting times where this is so. This just doesn't look right. OTOH, we sit on a relatively high spot in the county and my anemometer does have an unlimited view to the horizon; maybe this has something to do with my readings.

I went with their new pro anemometer and have really been pleased. I spins up at a wind of no more than 2 mph. Of course you may have to have your console upgraded as the new anemometer is capable of reading tenths of a mph. I also send data to weather underground from a old heath kit, which has the a very sensitive anemometer. Threshold is 1 mph and has "frictionless" bearings?

First, your CWOP "CW" station ID is coded as Cxxxx_MADIS on the NOHRSC (very similar to COCORAHS). Interesting enough, the COCORAHS "converted" IDs are are totally different from the actual COCORAHS IDs (which are something like SS-CO-XX). I haven't yet figured out yet what NOHRSC is doing with the CWOP "NOAA" alias for the Ham Radio call signs. So where are your snow reports? Well, nothing good is easy! First, find your data in the tables links listed at the bottom of this page: http://www.nohrsc.noaa.gov/nsa/ Click on the "Station Snowfall Reports" or the "Station Snowdepth Reports" links. Let the page load, then search in your full (not alias) CWOP station ID, ex. CW4199. I found these NOHRSC IDs and Station Desctriptions: C0003_MADIS CW0003 CARLISLE C0609_MADIS CW0609 WINTERPOCK C1411_MADIS CW1411 VISCHER FERRY C1773_MADIS CW1773 LISBON C4199_MADIS CW4199 JACKSON Here is the time series links for these stations: http://www.nohrsc.noaa.gov/interactive/html/graph.html?units=0&station=C0003_MADIS&x=-71.3735&y=42.5445 http://www.nohrsc.noaa.gov/interactive/html/graph.html?units=0&station=C0609_MADIS http://www.nohrsc.noaa.gov/interactive/html/graph.html?units=0&station=C1411_MADIS http://www.nohrsc.noaa.gov/interactive/html/graph.html?units=0&station=C1773_MADIS http://www.nohrsc.noaa.gov/interactive/html/graph.html?units=0&station=C4199_MADIS Here is the plots for some of the above stations: http://www.nohrsc.noaa.gov/interactive/html/map.html?mode=query&zoom=¢er_x=++-72.555¢er_y=+++44.537&ql=obs_overlay&var=snowfall_obs_24_h&dy=2007&dm=2&dd=1&dh=12&snap=1&o9=1&o12=1&o13=1&lbl=m&min_x=-72.567083333325&min_y=43.68000068664&max_x=-70.967083333325&max_y=44.88000068664&coord_x=-71.76708333332499&coord_y=44.28000068664&zbox_n=&zbox_s=&zbox_e=&zbox_w=&metric=0&bgvar=dem&width=600&height=450&nw=600&nh=450&type=0&js=1&uc=0 http://www.nohrsc.noaa.gov/interactive/html/map.html?mode=pan&zoom=¢er_x=+-106.3¢er_y=+++54.6&query.x=26&query.y=9&ql=obs_overlay&var=snow_depth_obs_24_h&dy=2007&dm=2&dd=2&dh=12&snap=1&o9=1&o12=1&o13=1&lbl=m&min_x=-89.475416666658&min_y=35.271667353307&max_x=-88.267083333325&max_y=36.180000686641&coord_x=-88.8712499999915&coord_y=35.725834019974&zbox_n=&zbox_s=&zbox_e=&zbox_w=&metric=0&bgvar=dem&width=600&height=450&nw=600&nh=450&type=0&js=1&uc=0 You see your data on the map, set the "Interactive Snow Info" Page (link: http://www.nohrsc.noaa.gov/interactive/html/map.html) widgets to: Select Physical Elements: Total Snow Fall (24, 48, or 72 hrs) or Total Snow Depth (24, 48, or 72 hrs) Select Date: This is the time increment "ending" time of an accumulation or the actual time of a snow depth observation; time in "Z" or UTC (Greenich, England), so 07:00 Local (EST) is 12:00 UTC (5 hour ahead of local time), Z time is 6 hrs ahead of Central time, etc. Select Point Features: Cities and Stations should be "checked" by default, you can "turn on" (display) the feature by clicking on the label; I did not find the "Stations" useful since only the COOP and ASOS station labels appear while CWOP and COCORAHS are not currently displayed. .... then Click on "Redraw Map" What will happen (at least in the winter season), is hundreds of stations will be plotted. You will have to do some probing to find your data (however, if you did not report during the time requested, then you won't find any plots for yoru station). 1. First, click in one of the little icons in the "Navigation Tools" section (top of interactive menu) 2. Next, "rubber band" zone on your region by clicking and dragging northwest to southest across your area of interest on the map; do this a couple times starting with a large "zoom box: and working your way down to a 3-5 county scale where the reports are not on top of each other Your station's data plot will not have a station ID next to it (see note above), so it is a trick to determine which of the plots on the map are your's. Here is what to do: 1. After zooming down, click on the "i" square on the data "Query" section (upper left of the interactive menu); the buttom should turn red. 2. Scroll down the query list to the bottom, and select the "Latest Observations" data type 3. Now, move your cursor over the map in the area where your station is located, slowly moving the cursor over the plot. Your station name will magically pop up when the cursor is over your station plot! 4. If you click on your station plot now, a time series plot for your station will be displyed in a new browser window. Figuring out the tool is best done by playing aound with it. It is very difficult for me to describe the functionality in words for the interactive snow tool info tool since the page has so many ways to probe for data. Carries @ NOHRSC sent along this link as a backgrounder for the data types: http://www.nohrsc.noaa.gov/technology/pdf/Snowfall_Maps.pdf Remember, the NOHRSC folks are tasked to come up with the solution to the hydrologic problem, "how much snow is there within the river basin, and how muchof this snow will melt and contribute to the river level and flow". So, they design their tools to help answer this question. Ultimately, they don't really care about snow, just the water trapped in the snow. There have been some historic floods where the snow pack significantly contriuted to the flooding, I recall the Potomac River in 1996, and the Red River (North Dakota) in 1997. I am not sure how long it takes for a report entered into the MADIS Snow Data Entry, to appear on the NOHRSC map; I assume a couple hours. It is worth your time to also report your snowfall/snowdepth to your local Weather Forecast Office using their Skywarn snow report procedures. That way, your reports will be sure to get into their Public Info Statements which typically include snow reports.

Suddenly, my station appears to be drifting off target for no apparent reason. I'm not off by a drastic amount, but it is enough to raise questions. I have taken a .2MB correction, but I'm still drifting. My question, there is a neighboring station listed K08C that is drastically off by 23.9mb! Is this station the reason my barometer data is suddenly drifting? I'm no mathematical genius, but should a station that is that for off, be used for MADIS calculations? -------------- next part -------------- A non-text attachment was scrubbed...

I am having a terrible time with my barometer. I changed all the batteries and made sure the connection is working, but now it is WORSE than before, and I didn't do any tweaking. Sigh. Sorry to be so...unable... It is an Oregon Scientific wireless. Any help, suggestions, do this and this and this, is much appreciated. Does it matter that stations I can use to set my barometer by are at least 20 miles away and in not as hilly locations?

In such a situation, the barometric pressure should be pretty uniform. That's what I did to set mine. I had to wait a couple weeks until the conditions were calm and consistent enough.

Unfortunately when the tornado hit, the station was not fully operational nor was it online to any services. His house was directly in the path of the storm and at the time the storm hit what I recovered of the log replaced the barometric pressure with "Barometer error". The anemometer had not been mounted as of yet so only a 4 MPH wind reading was recorded, but then again the wind cups were down in the grass where they shouldn't have been able to move at all.

Tom Hybiske, K3GM (AR824) Is there still an effort to have sites submit photos to Flickr? I uploaded photos several days ago and believe I have them properly tagged, but so far they haven't shown up on my site page. Is there something I forgot to do to get them to show up? DO you just add the tags, and wait? Thanks, Tom Hybiske, K3GM --------------------------------- It's here! Your new message! Get new email alerts with the free Yahoo!

We rushed into mounting it faster than we researched everything :( I have to figure out how to get most of the stuff down lower and attach it. It's too far away from the house to lean on, and it's an aluminum pole, so sways too easily too :( may have to figure out some way of guy-ing it. I'm thinking I need to find someone with a cherry-picker or take the whole pole out of the ground. Neither sounds easy. Maybe this spring we'll figure something out.

That was the best place I could find where it was out of direct sunlight.

This means that your sensor is reading COLDER than expected. There is a significant mean error in your dewpoint readings. You may need to calibrate your dewpoint sensor. Adjust your sensor to read 3.4 ?F higher. Your readings are not within an acceptable error range. The automated problem analysis cannot identify the problem. You can signup on the wxqc mailing list and post information about this situation there. This is may be caused by poor siting of the sensor (e.g. under eves, in screen porch, or in thick tree coverage). For information on siting, see CWOP Station Guide. D.

The only issue is to use the red solution or liquid mercury in the thermometer. We used to play with the liquid mercury when we broke thermometers when I was a kid, but that is not advised anymore (rather, call out the HAZMAT team). You just need to be careful where and how you sling your sling so as not to hit your leg or other solid objects if using a liquid mercury sling. You can get a good price on Ebay: http://search.ebay.com/search/search.dll?cgiurl=http%3A%2F%2Fcgi.ebay.com%2Fws%2F&fkr=1&from=R8&satitle=sling+psychrometer&category0=&submitSearch=Search There is no downside to buying a used sling, just make sure you are getting clean/new wicks for the wet bulb sensor. It is good to use distilled water to keep the wick clean of contaminants, but you can get that at the drug store pretty cheap.
