The following table provides information around the Flag 124-126 of the GSOD Weather dataset the documentation of which is available here:
Flag 124-124 Char A = 1 report of 6-hour precipitation amount. B = Summation of 2 reports of 6-hour precipitation amount. C = Summation of 3 reports of 6-hour precipitation amount. D = Summation of 4 reports of 6-hour precipitation amount. E = 1 report of 12-hour precipitation amount. F = Summation of 2 reports of 12-hour precipitation amount. G = 1 report of 24-hour precipitation amount. H = Station reported '0' as the amount for the day (eg, from 6-hour reports), but also reported at least one occurrence of precipitation in hourly observations--this could indicate a trace occurred, but should be considered as incomplete data for the day. I = Station did not report any precip data for the day and did not report any occurrences of precipitation in its hourly observations--it's still possible that precip occurred but was not reported.
My question is around clarity of flags A to F which indicates precipitation amounts for periods shorter than 24 hours. For those flags must the precipitation amount be multiplied to reach a 24 hour period?
E.g. if the field = 0.10A (A = 1 report of 6-hour precipitation amount) is the total precipitation amount 0.10 * 4 = 0.40?
If not then what is the the purpose of noting that the amount reported is recorded for a 6 hour period?
