Howdy all,
Here's a little clarification on those WMO headers, or what they should
represent anyways:
https://www.weather.gov/tg/tablea
For reference, the 6 character WMO header can be broken down thusly (T1 T2
A1 A2 ii). On the above page I is for "Binary observation - BUFR" so
that's what we're expecting. You can click those table links to the right
on that row to understand what the remaining characters mean...
When T1 is I, T2 designates the data type. S is for surface/sea level, U
is for upper air (soundings). So given this, Greg's pattern is matching
surface data and not soundings.
A1 depends on if we're looking at surface or upper air (
https://www.weather.gov/tg/tablec6). IUS for example should be
"Radiosondes/pibal reports" while ISS would be for "Floating platforms
(ship, bouy[sic], etc.)" originating data.
A2 starts to define regions, this is the first character that represents
any form of location (at least for T1=I products
https://www.weather.gov/tg/tablec3). Other regional information can be
derived from the originating office identifier.
ii can be many things, it's common to be a form of a region code but that
does not seem to be the case here. On that first table page all that's
listed is **, and the only worthwhile explanation is on page 59 of this:
https://library.wmo.int/records/item/35800-manual-on-the-global-telecommunication-system
Short version is I _think_ these are simply unique identifiers for these
types of reports, but they may have other meaning depending on the issuing
agency. Either way though, I don't _think_ this is region/location info as
that all seems to be defined in A2. Note the level of confidence in my
"voice" however.
Devin:
I believe what you are looking for would be ^I[SU].... and you can narrow
it down from there to meet your needs.
Greg:
^IS[IMN] looks like it will only get a few sources of surface obs, for your
missing data have you tried opening that up to anything (^IS....)?
For what it's worth I think these only come over the HDS feed, at least
that's where I've always seen them.
Hopefully that info helps more than confuses, let me know if I should
clarify anything.
Best,
-Mike
