BAS decoded CLIMAT TEMP data
Caution! The data here has been extracted from GTS CLIMAT TEMP messages
(using my program clt.pl). It has not been checked.
There are known problems with some CLT's: for example, the Halley AIR software was
known at one point to be producing them incorrectly.
So, use this data if you like but be cautious.
At the very least I advise you to graph it out to check for outliers!
I put this up hoping it will be useful: if you do find any errors, please let me know.
Data format
Data files are in ascii, one per year. Here is some example data:
89050 1994 12 1 18 1 1199 -4.4 042 01
89050 1994 12 1 18 2 2713 -12.3 071 01
89050 1994 12 1 18 3 5207 -27.7 082 01
The lines are:
- 89050 - station ID
- 1994 12 1 18 - year, month, day, hour (hour is set according to: 0 for 0Z, 12 for 12Z, 6 for avg(0,12) and 18 otherwise)
- 1 (2,3) - level number (e.g. level 3 is (usually) 500 hPa. You can work these out from the heights or read the code book...)
- 1199 (2713,5207) - pressure at that level
- -4.4 (etc) - temperature
- 042 (etc) - dewpoint depression in tenths of oC. I would trust this less than the temperature, if I were you.
- 01 - number of days in month for which temp obs are missing
