UCOSE Codes
Example:
Definition of symbols:
First Line-
- UCOSE comes from COSmic rays, code E
- I I I I I = station indicator
- DD = UT day of first period for which flux values are given
- T = type of apparatus
- 0 = neutron monitor (IGY-Simpson type)
- 1 = high counting rate neutron monitor (IQSY-type)
- 2 = meson monitor (IGY-type)
- 3 = meson monitor (IQSY type)
- 4 = telescope, no shielding
- 5 = ionization chamber
- HH = UT hour of message (normally in the UT day following the date of DD)
- a = type of variation during the day
- 0 = normal daily variation
- 1 = beginning of a pre-decrease
- 2 = pre-decrease
- 3 = commencement of a Forbush decrease
- 4 = Forbush decrease
- 5 = recurrent activity
- 6 = increase
- 7 = after-effect of increase
- 8 = daily variation of large amplitude
- 9 = daily variation of anomalous phase
- b = sign of daily variation (below or above arbitrary level)
- 7 = negative
- 8 = zero
- 9 = positive
- c c c = average deviation expressed in steps of thousandths of an arbitrary mean level
- HH = UT hour indicator; deviation of flux from the normal value following with ddd refers to the interval HH-1 to HH+1 hours; if the deviation is positive, 30 is added to the hour to obtain HH
- ddd = deviation of cosmic ray flux from level expressed by steps of thousandths of an arbitrary mean count
Note: The arbitrary level is selected so that the deviations can be specified by three digits.
The arbitrary level is always chosen higher than the actual level (see example below).
Note: / is to be used for data not available.
