Please use our 
On-line costing to order this dataset.
Description:
- period available is 1 January 1979 to 31 December 1993;
- This data set contains only accumulating fields from the forecast
with the following data available:
- 24 hour accumulations are available from forecasts beginning at 0000 and 1200 UTC.
- 6 hour accumulations are available from 0000 to 0600 UTC, 0600 to 1200 UTC, 1200 to 1800 UTC, 1800 to 2400 UTC.
- 6 hour accumulations use forecast time periods designed to minimise the effects of spin-up.
The values used will be as follows:
