I have noticed that there seems to be a problem in the dcmetr decoder.
For combined precip types, incorrect intensities are reported.
By example, for this report (April 3rd, 2007):
CYRJ 031851Z 12008KT 10SM -RAPL OVC002 RMK ST8 VIS S-SW 2BR
The dcmetr decoder stores, in the WMO current weather, an incorrect
intensity for the ice pellets precip type. It reports light rain and
moderate ice pellets, instead of light rain and light ice pellets.
This also happens for triple precip types, such as -RAPLSN.
