统一回复数据变量缩写的问题：
01-06 USAF = AIR FORCE CATALOG STATION NUMBER
08-12 WBAN = NCDC WBAN NUMBER
14-25 YR--MODAHRMN = YEAR-MONTH-DAY-HOUR-MINUTE IN GREENWICH MEAN TIME (GMT)
27-29 DIR = WIND DIRECTION IN COMPASS DEGREES, 990 = VARIABLE, REPORTED AS
'***' WHEN AIR IS CALM (SPD WILL THEN BE 000)
31-37 SPD & GUS = WIND SPEED & GUST IN MILES PER HOUR
39-41 CLG = CLOUD CEILING--LOWEST OPAQUE LAYER
WITH 5/8 OR GREATER COVERAGE, IN HUNDREDS OF FEET,
722 = UNLIMITED
43-45 SKC = SKY COVER -- CLR-CLEAR, SCT-SCATTERED-1/8 TO 4/8,
BKN-BROKEN-5/8 TO 7/8, OVC-OVERCAST,
OBS-OBSCURED, POB-PARTIAL OBSCURATION
47-47 L = LOW CLOUD TYPE, SEE BELOW
49-49 M = MIDDLE CLOUD TYPE, SEE BELOW
51-51 H = HIGH CLOUD TYPE, SEE BELOW
53-56 VSB = VISIBILITY IN STATUTE MILES TO NEAREST TENTH
NOTE: FOR SOME STATIONS, VISIBILITY IS REPORTED ONLY UP TO A
MAXIMUM OF 7 OR 10 MILES IN METAR OBSERVATIONS, BUT TO HIGHER
VALUES IN SYNOPTIC OBSERVATIONS, WHICH CAUSES THE VALUES TO
FLUCTUATE FROM ONE DATA RECORD TO THE NEXT. ALSO, VALUES
ORIGINALLY REPORTED AS '10' MAY APPEAR AS '10.1' DUE TO DATA
BEING ARCHIVED IN METRIC UNITS AND CONVERTED BACK TO ENGLISH.
58-68 MW MW MW MW = MANUALLY OBSERVED PRESENT WEATHER--LISTED BELOW IN MANUALLY OBSERVED PRESENT WEATHER TABLE
70-80 AW AW AW AW = AUTO-OBSERVED PRESENT WEATHER--LISTED BELOW IN AUTO-OBSERVED PRESENT WEATHER TABLE
82-82 W = PAST WEATHER INDICATOR, SEE BELOW
84-92 TEMP & DEWP = TEMPERATURE & DEW POINT IN FAHRENHEIT
94-99 SLP = SEA LEVEL PRESSURE IN MILLIBARS TO NEAREST TENTH
101-105 ALT = ALTIMETER SETTING IN INCHES TO NEAREST HUNDREDTH
107-112 STP = STATION PRESSURE IN MILLIBARS TO NEAREST TENTH
114-116 MAX = MAXIMUM TEMPERATURE IN FAHRENHEIT (TIME PERIOD VARIES)
118-120 MIN = MINIMUM TEMPERATURE IN FAHRENHEIT (TIME PERIOD VARIES)
122-126 PCP01 = 1-HOUR LIQUID PRECIP REPORT IN INCHES AND HUNDREDTHS --
THAT IS, THE PRECIP FOR THE PRECEDING 1 HOUR PERIOD
128-132 PCP06 = 6-HOUR LIQUID PRECIP REPORT IN INCHES AND HUNDREDTHS --
THAT IS, THE PRECIP FOR THE PRECEDING 6 HOUR PERIOD
134-138 PCP24 = 24-HOUR LIQUID PRECIP REPORT IN INCHES AND HUNDREDTHS
THAT IS, THE PRECIP FOR THE PRECEDING 24 HOUR PERIOD
140-144 PCPXX = LIQUID PRECIP REPORT IN INCHES AND HUNDREDTHS, FOR
A PERIOD OTHER THAN 1, 6, OR 24 HOURS (USUALLY FOR 12 HOUR PERIOD
FOR STATIONS OUTSIDE THE U.S., AND FOR 3 HOUR PERIOD FOR THE U.S.)
T = TRACE FOR ANY PRECIP FIELD
146-147 SD = SNOW DEPTH IN INCHES
NOTES:
- *'s IN FIELD INDICATES ELEMENT NOT REPORTED. |
