[METNO C] Norwegian TEMP SHIP and German SYNOP

Today’s METNO C (ftp://ftp.wmo.int/wmo-ddbs/OperationalInfo/VolumeC1/From_WMO/METNO/2015/MC0615.txt) says:

 

l  Norwegian TEMP SHIP for LGKI has stopped on Jan 23, and the report is given in BUFR IU[KS]D52 ENMI

l  German SYNOP SXDL2[12] and SXDL4[4-9] EDZW has stopped on Jan 27.

 

 

Bhutan gets new AA=BT/CCCC=BTBH; Astana, Kazakhstan gets new CCCC=UAST

Messages flowing on the GTS (WMO's Global Telecommunication System) are identified by the abbreviated heading,
starting with two coded words called TTAAii CCCC (more correctly T₁T₂A₁A₂ii is the formal name, but suffix letters are often omitted in everyday communications).

In most cases CCCC represents the originating center. It is often
confused with ICAO's location indicator, since they are the same for
many countries (for example RJTD is Tokyo JMA), but they are controlled
separately now and actually different for some countries (the Bureau of
Meteorology at Melbourne is called AMMC on GTS, but ICAO indicator for
Australia begins with Y, for example Melbourne Airport is YMML). The
first two letters usually represents the country: once a CCCC is
allocated, the country may use other CCCC codes starting with the same
first two letters (there're exceptional collisions).
The AA is another system of country code. For example
TTAAii=SMJP01 means (S) surface (M) main-hour synoptic reports from
(JP) Japan.

Bhutan is being connected to GTS now, and thus needed both AA and CCCC
codes to create new heading of their data, which will probably be
something like SMBT01 BTBH (the number ii can be different).

Astana seems to be an additional originating center in addition to
Almaty (UAAA). Kazakhstan already has AA=KZ so no allocation is done
this time.

Below is excerpt from the operational newsletter of WMO:

# GTS regulatory or guidance material

## Allocation of data designators T1T2A1A2ii CCCC for use in abbreviated
headings of meteorological messages

Effective immediately include the following geographical designator A1A2
for use in the abbreviated heading T1T2A1A2ii CCCC:

* Country Name: Bhutan
* RTH Centre: New Delhi (India)
* Country/Territory (AA) designator: BT
* Location indicator (CCCC): BTBH

* Effective immediately include the following new CCCC:
* Country Name: Kazakhstan
* Addition Centre from Kazakhstan: Astana
* Location indicator (CCCC): UAST

[METNO C] Netherlands says they stopped TAC TEMP, but....

Yesterday Geneva published a new METNO C and it says Netherlands has stopped their TAC TEMP on Friday 23.  However, Tokyo is still receiving ULNL01 (TEMP Part C) and UENL01 (Part D) even today.  I don’t know what’s happening….

TDCF migration of upper-air sounding data

The World Meteorological Organization (WMO) has been working for TDCF migration, which is transition from observation reports and forecast messages in TAC (traditional alphanumeric codes) into TDCF (table-driven code forms) namely BUFR (binary universal representation) and CREX.  For most of message types, the parallel distributions were scheduled up to November 2014.  

Some countries actually stopped their TAC distributions, and
it turned out that the meteorology community needs more work to get fully ready to the transition, especially for upper-air sounding.  The situation was complicated since WMO tried to change not only code but reporting practice, as discussed in following forum thread:

https://groups.google.com/a/wmo.int/forum/m/#!topic/cbs-ipet-drmm/ZcwvuCRCTH0

Traditionally, the alphanumeric messages for a single ascent of radiosonde are supposed to be disseminated in four parts:

• Part A: standard isobaric levels up to 100 hPa
• Part B: significant levels up to 100 hPa
• Part C: standard isobaric levels above 100 hPa
• Part D: significant levels above 100 hPa

The standard isobaric levels are 1000, 925, 850, 700, 500, 400, 300, 250, 150, and 100 for Part A; and 70, 50, 30 and 10 hPa for Part C.  Weather charts are supposed to be drawn at those levels (JMA's charts are available at http://www.jma.go.jp/jp/metcht/kosou.html).

The significant levels (in Parts B and D) supplements standard levels so that linear interpolation of all reported data (both standard and significant levels) gives enough accuracy.  Roughly they are chosen at kinks of plots of temperature, humidity, and winds  (a good illustration of temperature siglevs is given at ECMWF website).  Please see the Manual on Codes Volume I.1 for the complex rules for selecting significant levels.

Then, why do we split messages at 100 hPa?  The answer is time of delivery.  The 100 hPa level lies 16 km above sea level.  Typical radiosonde has 6 m/s speed.  It takes 45 minutes to reach that level.  The time may double if we wait for the end of ascent: that's why WMO member states agreed to split the report.

In the new paradigm of BUFR, there is a rule called B/C 20 and 25 to determine how to migrate from TAC to BUFR:
https://www.wmo.int/pages/prog/www/WMOCodes/BC_Regulations/BC20-PILOT.pdf
https://www.wmo.int/pages/prog/www/WMOCodes/BC_Regulations/BC25-TEMP.pdf
It describes two messages should be sent for a single ascent:

• Standard and significant levels up to 100 hPa
• Standard and significant levels above 100 hPa

I guess the designers of the rules thought "the reason for splitting Parts A-B and C-D is simply for size of bulletins;  now the size limitation of GTS bulletins are being eliminated;  why don't we merge unnecessary split?"

That was correct, but the meaning or value of the reporting style was not stressed.  So implementers simply used the template only and ignored the text regulations.  Most implementations simply converts existing TAC to BUFR in parts.

It was supposed that BUFR would get the mainstream, i.e. observation systems directly generated BUFR and TAC were made as a compatibility service.  By doing so we could eliminate various problems of TAC reports.  But that mainstreaming did not take place in many WMO members.  I suspect the change of the rule is even not known for many people working for observation systems.  So the part-for-part converter had to be chosen.

There are many benefits of BUFR-mainstreamed data processing, which is basically straightforward handling of numbers.  For example 1000's digit of geopotential height in lower troposphere is omitted in FM 35 TEMP.   If 700 hPa height is 3451 metres, only digits "451" is shown in the report, and the recipient has to guess the lost digit using "common sense".  It is usually 3451 m in most of the world, but it can be 2451 m in very cold places like Antarctica, so it is a headache for automated system.  A simple-minded converter always generates BUFR with 3451 m value for TAC input "451" which may be incorrect.  But the benefit has not so stressed for these decades, and I don't think many understand it.

Right now there are many proposals to change the part-by-part converted BUFRs to distinguish Parts A-D.  But I'd really remind the situation filled by a whole bunch of unimplemented regulations and ununderstood good intentions.  I think we must be really careful for changing rules, since current one takes many years to be understood partly.

Horizontal and Vertical Datums in Operational Meteorology

Tommorow afternoon I'll talk about the idea below in OGC Met-Ocean DWG.  Hope that makes sense for them.

---

Volume A, Publication 9 of WMO is a catalogue of observing stations, compiled from submission from WMO's member states.  That, of course, includes latitude, longitude and hight above MSL (mean sea level), which are measured from some datum.  Which datum?  That is the question.

Honestly I don't know.  And I'd like to be honest.  So I'd like to make it clear that the datum is unclear.

Recommendation 1, CBS-Ext.(06) recommended that WGS 84 and EGM-96 are the references i.e. datums for coodinates and hight measurement.  But I saw not so much coordinates in the catalogue has changed since then.  So it is highly likely that many member states do not recognise what the recommendation is, and the coordinates/hight measured from past national datums are still listed.

For horizontal coordinates i.e. latitude/longitude that is no problem.  Volume A used to have one arc-minute precision.  The format has been changed to have one arc-second precision, but there are still a bunch of entries with zero-zero seconds.  One arc-minute is roughly one kilometer on the earth, and that is the precision of meteorological analysis.  If there is some coordinates data from different datum, the difference is usually less than a kilometer, so we can live with the situation.

Vertical datum is different.  Some national datums have difference more than one meter from EGM-96.  And we want 0.01 m precision (even the old format had one meter precision). One meter error means 0.1 hPa error in pressure, which is significant in operational meteorology.

So we need to be clear that the datum is unclear.
