(water equivalent) accumulated in the past 3 hours in the 3-
(See Note 2) hourly report; and the amount accumulated in the past 6

hours in the 6-hourly report. The amount of precipitation is
(METAR only) encoded in inches, using the tens, units, tenths and
hundredths digits of the amount. When an indeterminable

amount of precipitation has occurred during the period,
encode RRRR as 6////. For example, 2.17 inches of
precipitation would be encoded "60217." A trace will be
encoded "60000."
28 24-Hour Encode the 24-hour precipitation amount in format, X X O

Precipitation 7R24R24R24R24, where 7 is the group indicator and
Amount R24R24R24R24 is the 24-hour precipitation amount. Include the
24-hour precipitation amount in the 1200 UTC (or

(See Note 2) MAJCOM/Higher Headquarters designated time) whenever
more than a trace of precipitation (water equivalent) has
(METAR only) fallen in the preceding 24 hours. The amount of precipitation
is encoded by using the tens, units, tenths, and hundredths of
inches (water equivalent) for the 24-hour period. If more than

a trace (water equivalent) has occurred and the amount
cannot be determined, encode the group as 7////. For example,
1.25 inches of precipitation (water equivalent) in the past 24
hours will be encoded "70125."

29 Snow Depth on Encode snow depth during controlled airfield hours in the X(*) X O
Ground 0000, 0600, 1200, and 1800 UTC observation, or MAJCOM
specified reporting time for your installation, when
(See Note 2) supplementing for snow depth. The remark is encoded in the

format, 4/sss, where 4/ is the group indicator and sss is the
(METAR only)
