A) Addition/corrections already approved or entirely editorial
It is proposed
1) To add Note (8) under Class 13 referring to 0 13 155 (Intensity of precipitation):
An intensity of precipitation value of -0.00001 kg m-2 s-1 before scaling (-1 after scaling) and
of -0.1 mm h-1 before scaling (-1 after scaling) shall indicate a "trace" in BUFR and in CREX,
respectively.
2) To correct name of 0 02 064 in 3 11 006 and 3 11 007:
The name of 0 02 064 is currently included in 3 11 006 and 3 11 007 as “Roll angle quality”.
It should be corrected to “Aircraft roll angle quality” to be in compliance with BUFR Table
B.
3) To correct name of 0 33 026 in 3 11 004:
The name of 0 33 026 is currently included in 3 11 004 as “Mixing ratio quality”. It should be
corrected to “Moisture quality” to be in compliance with BUFR Table B.
B) Other modifications
It is proposed
1) To modify name of 0 12 001, 0 12 101, 0 12 004 and 0 12 104:
The name of 0 12 001 and 0 12 101 is given in BUFR Table B as “Temperature/dry bulb
temperature”. It is to be corrected to “Air temperature”.
The name of 0 12 004 and 0 12 104 is given in BUFR Table B as “Dry bulb temperature at 2
m”. It is to be modified to “Air temperature at 2 m”.
(The modification of the name of 0 12 101 was requested by WIGOS Pilot Project for
AMDAR, De Bilt, 10-12 Feb. 2009. For consistency, similar modification is proposed also for
0 12 001, 0 12 004 and 0 12 104).
2) To modify name of 0 33 025:
The name 0 33 025 is given in BUFR Table B as “ACARS interpolated values”. It is
proposed to be “ACARS interpolated values indicator”.
(This modification was requested by WIGOS Pilot Project for AMDAR, De Bilt, 10-12 Feb.
2009, later refined by Mr. Jeff Ator, USA).
