Although I've been a user of AS6.5 for some time, it's amazing what I have learned lately by READING THE MANUAL. I realise I've been missing quite a bit.However, I have a question regarding a series of numbers that appear in a METAR report for which I have not found an answer.This is the METAR for KDFW that I received earlier today:KDFW 102353Z 15015KT 10SM FEW060 SCT120 BKN300 38/17 A2969 RMK A02 SLP042 T03830172. Now up to this point I don't have a problem reading the report. After the last entry (T03830172) the following numbers appear: 10411 20367 56013. What do these numbers refer to?Obtaining a report later in the day for the same airport, this series of numbers nor anything similar did not appear.Thanks for your help.Jim D.

Hi,d. Hourly Temperature and Dew Point (TsnT'T'T'snT'dT'dT'd). At designated stations, the hourly temperature and dew point group shall be coded to the tenth of a degree Celsius in the format, TsnT'T'T'snT'dT'dT'd, where T is the group indicator, sn is the sign of the temperature, T'T'T' is the temperature, and T'dT'dT'd is the dew point (see paragraphs 10.5.1 and 10.5.3). The sign of the temperature and dew point shall be coded as 1 if the value is below 0

Thanks for the reply Jim. Took me a couple of times to understand it.Now here is another that just popped up:KDFW 111653Z 21007KT 10SM FEW080 SCT100 BKN300 31/22 A2983 RMK AO2 RAB37E49 SLP091 P0000 T03110217RAB37E49: I assume that this means RAin Began. But the following is a mystery to me, 37E49.Jim D.

Rain began 37 minutes past the hour, and ended at 49 minutes past the hour.

Hi All,For more info:http://weather.cod.edu/notes/metar.htmlhttp://www.nws.noaa.gov/oso/oso1/oso12/fmh1/fmh1toc.htmThanks!!Jimhttp://www.hifisim.com/banners/hifi-community-sigbanner.jpghttp://www.hifisim.com/

Thanks again.Jim D.

Thanks for the links. I'm not into an intense study of weather as promoted by by the governments booklet. I just want to understand the basic weather as provided by AS6.5. Still takes a bit of reading just to figure that out when a new code is presented.I think I'm set for now.Jim D.
