Hey Guys,Recently I have had this issue where if I load up, or am flying to an airport, for example 'YMMB' or Moorabbin, I get ADVANCED INTERPOLATION at the end, which I believe is just a metar made from the weather around this airport. However, when I type .metar YMMB in squawkbox, there is a full METAR, and this isnt being put in ASE, I'm just getting a interpolation metar. It seems to happen around most of the airport in AU, NZ etc. If I could have some help to fix this it would be greatly appreciated.Kind Regards,James

Hi,According to: http://weather.noaa.gov/weather/metar.shtmlYMMB is not a weather station as NOAA doesn't even have data for it. That is why it is Interpolated in ASE.Also the same may be true for other stations in that area or it is the fact that we only supply weather for known weather stations in FS.

Hi,I thought when I had the "Online VATSIM update" option ticked, it will just pull the METAR from the VATSIM servers, rather than NOAA. If you go here: http://www.vatsim.net/data/search_metar.php and put in YMMB, the real METAR is available. Is there anyway I can get that METAR to appear in ASE?Thanks for your quick reply,James

This is curious. I don't know for sure, but I think that HiFi's server gets its METAR reports from NOAA. If you look at the following site:ftp://tgftp.nws.noaa.gov/data/observations/metar/stations/You can see all the current METAR reports that NOAA has for the current forecast hour. There are quite a few Autralian airports, but YMMB is not in the list.However, YMMB is a valid METAR reporting station in the NOAA's master list of known WMO METAR sites, as shown in this file:http://aviationweather.gov/adds/metars/stations.txtAnd, indeed, YMMB does report METAR obs every 30 minutes, which you can see at the Australian Bureau of Meteorlogy web site:http://reg.bom.gov.au/reguser/by_prod/avia...metar_nat.shtmlYMMB is in "Area 30". You have to enter a user name and password to view the data, but the required login info is right on the web page.Current METARS are found on the Aussie BOM site for dozens of airports that do not appear on the NOAA's server.Yet, VATSIM does, in fact, have access to the Australian METARS that NOAA does not. As you said, if you enter YMMB on the VATSIM weather page, you'll get the very same METAR that is also found on the official Australian METAR site.The question is, why? That would be something that someone from VATSIM could best answer. It could well be that the Australian government met office only releases a limited subset of hourly METAR obs to met organizations in other countries, such as the U.S. NOAA. I do see that all the bigger international airports in OZ, such as YMML and YSSY are there on the NOAA server - it is the smaller airports that are lacking.Perhaps VATSIM has an agreement with the Australian Met office to have automatic access to ALL of the hourly METARS. Since there is a pretty large presence of active pilots and controllers in Australia and NZ on VATSIM, I wouldn't be surprised if someone in the organization was able to arrange such access.Whether HiFi could also obtain METAR info from the same source - (at least for Australia and New Zealand) - is something I don't know. NOAA doesn't really seem to care who uses their data, or for what purpose - but government-operated meteorlogical organizations like the Australian BOM, or UKMET, may well have policies that their public data can only be used for private, non-commercial operations. VATSIM would qualify, being a non-profit hobbiest group, but HiFi Simulations would probably not. The alternative explanation is that there is another public web or FTP site which has a more complete feed of worldwide METAR obs than what can be found at NOAA, and that is where VATSIM gets its weather data. If that is the case, it's certainly something that HiFi should look into - because the more "real" METARS that are available for a given region, the less interpolation that has to be done to fill in the gaps.Jim Barrett

Hi All,We do not use NOAA data.ASE is using multiple private sources for its data.

I've never tried the VATSIM metar option, but I think that in order for it to work, you have to load and process a flight plan. Not sure if you have to be online with Squawkbox as well, the ASE manual doesn't say so - just mentions the need to load a flight plan To get the VATSIM wx.Jim Barrett

No officials and homogeneous data?This is curious.And for ASv6.5?

I can't speak for HiFi, but I did work in television weather forecasting for a long time, and know about weather data sources. Here in the U.S. weather data can come from either the government National Weather Service, or from private companies that specialize in providing enhanced weather products.NWS/NOAA data is all well and good - it's free for anyone to download - but it doesn't cover all data needed for aviation. NWS is good for surface metars for the USA and Canada, and to a lesser extent, for metars outside of North America. They provide winds aloft data for the USA, but not for anywhere else in the world.As far as I can see, the ONLY way that a company like HiFi can provide a complete set of surface and aloft data for the whole world, is to get that data from more than one source.There are many commercial companies here in the US that specialize in providing enhanced aviation weather info (for a fee). Companies like Jeppesen, WSI, Accu-Weather, Weather Central etc. These companies re-package the US NOAA data, and add weather data from locations outside the US. This would be a necessity - especially for worldwide winds aloft, which NWS doesn't provide.I don't know which specific sources HiFi uses, but to get a complete hourly snapshot of surface and aloft aviation weather for the whole world, they would almost HAVE to use multiple sources to get the "complete picture". The more sources they use, the more homogenous (and complete) the data would be.I'm pretty sure that all the programs in the Active Sky series, from AS 6.5 right up to ASE use the same servers to download from.
