Re: [data-curation] U.S. Sites Still Manually-Taken METARs

Thanks Boris,

The reason I asked is because I see that KSWF is being transmitted, ergo my question. 

Appreciate it, 

Mike

Mike,

Good question!

Any AWOS installed these days is non-Federal, so it is funded privately

either by the owner of an airport, a private company (such a hospital

for their heliport), or the state.  There are additional costs involved

(1000s of dollars a year I believe) to establish longline communications

to WSMCR and add these site to NADIN (National Airspace Data

Interchange Network).  This allows the site's METARs to be transmitted to

NOAAPort, AIDAP (FAA line primarily for NOTAMs), and other aviation

communication services.

It is up to the owner of the AWOS to fund NADIN hook-up, and AWOS

vendors always try to sell this service.  Some AWOS upon commissiong

immediately have NADIN service paid for (KW40 was a recent example)

so their METARs show up right away.  Over the last 20 years or so,

I have noticed more and more AWOS have been getting NADIN service,

whether it be brand new sites, or sites that have been installed for years.

Currently, I know of about 240 AWOS unit installed in the U.S., but do not

have NADIN service yet.  There are likely several dozen more at least I do not

know of at any one time. The 240 number used to be a lot higher (~500)

years ago.

As to when new sites show up?  There is no centralized site or agency

that tracks this that I know of.  It is just a matter of scanning METAR

collectives and flagging the new sites with a program.

Additions to NADIN are usually on a Tue or Thu, often in the 28 and 56

day FAA database update cycle, but I have seen additions every day of

the week. 

For international new METAR sites, often I see additions on the 1st of

the month and that is seperate from the NADIN process, and more tied

to what is distributed on GTS and what a country chooses to add.  There

are many, many more METAR, and TAF and SYNOP sites for that matter,

that exist all over the world that we do not see on NOAAPort for any

number of reasons, but with time, more and more have been added. esp.

SYNOP sites.

Afternoon Boris...what's this mean? "just do not

have NADIN service at this time."

Thanks,

Some of these already have AWOS units installed, but just do not

have NADIN service at this time.
