Address:http://www.bluehill.org/discussion.txt Changed:2:43 PM on Friday, September 24, 2004 The site above is a reminder of the observations of yester-year when a much better description of weather was regularly available through the surface observations and the greatest care was taken to avoid the most trivial mistake. There were instances of updated forecasts due to data that the trained observer recorded that is not easily detected by satellite. I checked for observations from central and coastal Florida over the past 48 hours. No on site lightning detectors at the sites I checked. Equipment failure before wind gusts reach 60KT. My home weather station can do better than that and it runs for thirty hours after power failure - on triple A cells. Power blackouts - with no back-up generator. How much does it cost to repair or install a lightning detector? Is our government's debt so severe that we cannot even afford a workable system and have fallen behind some other nation's observation systems as a result? In the lower 48, plus Alaska, I have to go ten, twenty, and thirty years back into the logbooks in order to retrieve accurate and detailed surface observations, especially when studying events related to thunderstorm activity, nor'easters, blizzards and tropical cyclones.

Lou,
While nicely written, Blue Hill's plea for help compares apples to oranges and overlooks several key facts. Firstly, your home "Davis" or whatever other station doesn't require much in the way of voltage and can survive many hours on batteries. The AWOS/ASOS network contains an integrated network of sensors and electronics, including several high voltage instruments (ceilometer for one), and most definitely cannot operate on battery backup. The exception of this is the barometer which is a standalone unit. Secondly, these surface observations don't forget are owned now by the FAA and are first and foremost for aviation use. If the airport itself is closed to traffic, then in all likelihood there's no reason to maintain the system during a failure. However, what's most likely the case is that many of the ASOS/AWOS were up and running and logging data internally just fine, but their dial out connectivity was severred. The same would apply to your home weather station. If you're running on battery power but have no way to transmit your observation, then the same problem applies. As for lightning, almost all of these stations DO have lightning sensors. A check of NLDN data across Florida showed no thunderstorm activity associated with the landfall of Jeanne. Given it's tropical nature, nighttime landfall, overall weak appearance, and lack of sustained 50 dBZ echoes, I wouldn't have expected lighthning anyways. The only thunderstorms I saw were yesterday afternoon just offshore of West Palm, more due to afternoon heating than anything. These were included in the PBI observations.

Thanks for the info. I should have realized that my triple A battery cannot run FAA equipment. The stations I checked had "TSNO" in the RMK section of the obs as soon as personell were evacuated. Thank you for telling me about the connections being severed. I didn't think of that when I posted, because back in our days it didn't make a difference. SOAs were still logged in, so the climatological record was not interupted, not to say what the case is today because it's been a long time if you know what I mean. When the downsizing began I was informed about what this was going to mean. (1) The loss of vital observation data, not detectable by satellite, that would no longer be used in forecasting due to no on sight meteorologist or meterological technician. Over the past seven years, we have already seen some situations where timely amendments to the forecast would have been made had this data been available. (2) The effect on safety at airports. (3) Increased danger of loss of data during power failure. The automated system has been valuable in providing us with a significant increase in sites. However, we still need more stations with on site personell. Your post was very well written also. Thanks for filling me in on some important points.

You could have not said it better. It is a joke how these stations
malfunctioned in Florida. During Frances'landfall there were no surface obs coming in between Daytona Beach and West Palm Beach. That is a long stretch of real estate with no weather being reported, that kind of stuff happens in a third world country. That data was need to save peoples lives and property and some of the same stations went down in Jeanne, long before any hurricane force winds arrived. What really floored me was that the Punta Gorda site took a direct hit from Charley and stayed up, reporting critical wind speed data that was used to warn the people in Charley's path. Why would one site get blasted and stay on line when other sites go down with much less wind. What was the difference between the two reporting sites.

1.) Punta Gorda ASOS did not stay online. It was put out of commission subsequently after a 109 mph wind gust, some 10-15 minutes before the strongest winds hit (go back and note the time and surface pressure of that observation). PGD went through an outer and inner eyewall and reported critical information about what was going to occur as Charley went farther into the interior of central Florida. Some people like to and need to specifically know what is coming at them. 2.) How would surface observations have saved lives and property, considering hurricane warnings had been out for 2 days. This is the most ridiculous nonsense I've read this week and it's only Thursday. Would the hurricane go "OH NO I'VE BEEN MEASURED!" and quickly weaken to prevent further damage? ![]() That data was crucial for the Orlando metro area in that before power went out, the local media warned the residents of a highly populated region to be prepared for 100+ mph wind gusts, some of the highest ever recorded at the local airport. If it wasn't for the PGD ob some people would have ventured out with no respect of the power of Charley. People depend on continuous updates of the weather, they will take it in any way shape or form and surface observations are very crucial. Knowing that 100+ mph damaging winds are coming to your area would convince some people well inland to be serious about protecting there lives and property. What do you proprose as a solution? If you actually took the time to read the previous posts, you're realize that the obs are under FAA control now. When the airport is closed for commercial traffic, they simply don't give a hoot!

So, instead of blasting at a poor, defenseless instrument array full of metal parts, why not contact the local airport representative(s) and ask them how their power feed and more importantly their COMMUNICATIONS feed are wired and why they failed in tropical storm force winds? Why do some ASOS stations handle hurricane force winds while others malfunction in TS force winds or even less. Why do some ASOS stations continue to report after commercial traffic is closed while others don't. Could it be a lack of simple inexpensive maintenance?

Regards, Lou It is sad that the observations we had years ago are decreasingly accurate today. Hopefully one day things will be back to the standards they used to be. At the same time, we should probably remember the thing's we've gained: 1 - Many more reporting stations, often in rather remote locations. 2 - More reliable reporting schedules... an automated station isn't going to fall asleep or go home for breakfast... 3 - Increased accuracy in reports, including SLP, temperature, wind, ceiling (below 12,000 feet), and rainfall... Of course, there are some things that will take a while to improve, including: 1 - Snowfall and snow rate. 2 - True sky cover. 3 - Precipitation type. It will take some advancements in technology to get these items reported more accurately. One thing that is dissapointing is that at many airports that formerly had part-time observers, they are still there but just monitoring the system. The FAA has a rating system for airports based on observation quality: (from http://www.faa.gov/atpubs/SWO/appendix_d.htm ) ++++++++++++++++++++++++++++++++++++++++++++++++++ +++++++++ Service Level D This level of service consists of an ASOS continually measuring the atmosphere at a point near the runway. The ASOS senses and measures the weather parameters listed below: - Wind - Visibility - Precipitation/Obstruction to vision - Cloud height and sky cover - Temperature and dewpoint - Altimeter - Freezing rain capability - Lightning reporting capability KSMQ, Someset Airport, Somerville, NJ is an example of Service Level D. ++++++++++++++++++++++++++++++++++++++++++++++++++ +++++++++ Service Level C Service Level C consists of all the elements of Service Level D plus augmentation and backup of the system by a human observer or an air traffic control specialist on location nearby. The National Air Traffic Controllers Association (NATCA), the group representing the interests of the air traffic controllers, and the FAA have agreed that at this level of service, the air traffic control specialists are allowed the option of adding operationally significant remarks. Backup consists of inserting the correct value if the system malfunctions or is unrepresentative. Augmentation consists of adding the weather elements listed below, if observed. - Thunderstorms - Tornadoes - Hail - Virga - Volcanic ash - Tower visibility - Any reportable weather elements considered operationally significant by the observer During hours that the observing facility is closed, the site reverts to Service Level D. ++++++++++++++++++++++++++++++++++++++++++++++++++ +++++++++ Service Level B Service Level B consists of all the elements of service levels C and D plus the elements listed below, if observed. - Longline RVR* at precedented sites (may be instantaneous readout) - Freezing drizzle versus freezing rain - Ice pellets - Snow depth and snow increasing rapidly remarks - Thunderstorm and lightning location remarks - Observed significant weather not at the station remarks ++++++++++++++++++++++++++++++++++++++++++++++++++ +++++++++ Service Level A Service Level A consists of all the elements of service levels B, C and D plus the elements listed below, if observed. - 10 minute longline RVR* at precedented sites or additional visibility increments of 1/8, 1/16 and 0 - Sector visibility - Variable sky condition - Cloud layers above 12,000 feet and cloud types - Widespread dust, sand and other obscurations - Volcanic eruptions ++++++++++++++++++++++++++++++++++++++++++++++++++ +++++++++ Much more information can be found he http://www.faa.gov/atpubs/SWO/index....0OF%20CONTENTS ===== Raymond C.

Lou, While nicely written, Blue Hill's plea for help compares apples to oranges and overlooks several key facts. Firstly, your home "Davis" or whatever other station doesn't require much in the way of voltage and can survive many hours on batteries. The AWOS/ASOS network contains an integrated network of sensors and electronics, including several high voltage instruments (ceilometer for one), and most definitely cannot operate on battery backup. The exception of this is the barometer which is a standalone unit. Secondly, these surface observations don't forget are owned now by the FAA and are first and foremost for aviation use. If the airport itself is closed to traffic, then in all likelihood there's no reason to maintain the system during a failure. However, what's most likely the case is that many of the ASOS/AWOS were up and running and logging data internally just fine, but their dial out connectivity was severred. The same would apply to your home weather station. If you're running on battery power but have no way to transmit your observation, then the same problem applies. As for lightning, almost all of these stations DO have lightning sensors. A check of NLDN data across Florida showed no thunderstorm activity associated with the landfall of Jeanne. Given it's tropical nature, nighttime landfall, overall weak appearance, and lack of sustained 50 dBZ echoes, I wouldn't have expected lighthning anyways. The only thunderstorms I saw were yesterday afternoon just offshore of West Palm, more due to afternoon heating than anything. These were included in the PBI observations. All very good points. Yes, there are higher power equipment in ASOS/AWOS installations which would probably have difficulty running on batteries. However, what about a generator? It is also a good point that many systems probably were not able to transmit. However, shouldn't there be back-ups for this? I would think that there would be alternate communication means if the primary means was unavailable. If TV crews are able to report from within a hurricane, the ASOS/AWOS stations should be able to report, as well. Also, granted that many systems do have lightning data fed into them from the national lightning data network and therefore can detect thunderstorms. However, there have been many times when I see TSNO in station obs. It is also maddening that the system automatically removes the TSNO if the oberver is logged in, even if the observer isn't augmenting the observations (many level of service C stations). I have noted this problem at stations many times. ===== Raymond C.
