没有，只是常见的气象数据(风速 风向 能见度 气压 气温 )。

您好，想问一下，数据中包含降水数据吗

楼主您好，万分感谢您的分享。数据已经下载下来了，想请教一下，这里面包含降水数据吗，数据后面几列中，PCP代表什么含义啊，PCP01，PCP06，PCP24，PCPXX

PCP01 = 1-HOUR LIQUID PRECIP REPORT IN INCHES AND HUNDREDTHS
PCP06 = 6-HOUR LIQUID PRECIP REPORT IN INCHES AND HUNDREDTHS
PCP24 = 24-HOUR LIQUID PRECIP REPORT IN INCHES AND HUNDREDTHS
PCPXX = LIQUID PRECIP REPORT IN INCHES AND HUNDREDTHS,美国以外站点通常是过去12小时的降水，美国的站点是过去3小时降水。

        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.

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.)
