ANSWERS to QUALITY CONTROL EXERCISE - CHAPTER 9<br />
2. METAR KDEF COR 292352Z 00000KT 25SM RA OVC065 33/31 A2995<br />
The contraction COR goes after the date/time group. RA should be coded RA.<br />
3. METAR KGHI 272155Z 05003KT 20SM BKN060TCU 19/11 A3003 RMK VCRA S W<br />
If any type of precipitation is observed with<strong>in</strong> 10SM of the station, it shall be reported <strong>in</strong> the body<br />
as “VCSH.” It may further be described <strong>in</strong> remarks. There is no such th<strong>in</strong>g as VCRA.<br />
4. METAR KJKL 022150Z 16006KT 20SM BKN065 M/M A3033 RMK<br />
If the temperature and/or dew po<strong>in</strong>t is miss<strong>in</strong>g, noth<strong>in</strong>g is to be reported. Never use “M” to report<br />
these values. Contraction RMK not needed.<br />
5. METAR KMNO 022045Z 08003KT 20SM TSRA OVC040 20/11 A2983 RMK TSRAB40<br />
The <strong>in</strong>tensity symbol is not entered <strong>in</strong> remarks for the beg<strong>in</strong> time of precipitation.<br />
6. METAR KPQR 232145Z 13003KT 20SM SHRA BKN050 TCU 19/14 A2985<br />
A space does not go between 050 and TCU. Also, hav<strong>in</strong>g 20SM visibility with a moderate ra<strong>in</strong><br />
shower is unlikely. The observer should have reported SHRA <strong>in</strong>stead.<br />
7. METAR KSTU 191150Z 0000KT 5SM BR BKN010 23/22 A2985<br />
Calm w<strong>in</strong>ds are reported with five zeros.<br />
8. METAR KVWX 282150Z 22002KT 20SM OVC035 18/10 A2992 RMK VCSHRA<br />
VCSH should be reported <strong>in</strong> the body of the report. There is no such comb<strong>in</strong>ation of descriptors<br />
and weather as VCSHRA. You cannot comb<strong>in</strong>e two descriptors <strong>in</strong>to the same group.<br />
9. METAR KYYY 051250Z 24002KT 5SM RASH OVC040 26/17 A2999<br />
The descriptor goes before the precipitation, i.e., SHRA.<br />
10. METAR KZZZ 142145Z 02010G18KT 20SM BKN060 18/06 A2977 RMK RA N MOV SE<br />
RA N MOV SE implies that it is with<strong>in</strong> 10SM of the station and thus it should be reported as VCSH<br />
<strong>in</strong> the body. The VCSH can further be described <strong>in</strong> remarks.<br />
11. METAR KAAA 202300Z 29004KT 20SM BKN065 24/16 A3000 10294 20100 TE42<br />
The contraction RMK is miss<strong>in</strong>g.<br />
12. METAR KBBB 010052Z COR 19025G35KT 160V220 6SM TSRA SQ FEW008 SCT018TCU<br />
BKN050CB 31/28 A2983 RMK WSHFT 25 TS SW TCU OHD MOV NE<br />
No errors.<br />
13. METAR KCCC 051951Z 00000KT 25SM 065BKN OVC100 29/20 A3045<br />
The height of the layer goes after the sky cover contraction.<br />
14. METAR KDDD 152247Z VAR04KT 15SM BKN250 30/22 A2999<br />
Variable contraction is VRB.<br />
15. METAR KEEE 1619150Z 22007KT 7SM SCT025 BKN100 OVC200 25/20 A3002<br />
The date/time group conta<strong>in</strong>s too many characters. There should be only seven characters count<strong>in</strong>g<br />
the Z.<br />
