Observations every 10-min, 10 stations for now but should increase, received at CMC by e-mail. Canadian radar data - will be available centrally at CMC, once NRP (National Radar Processor) becomes operational, in about 1 year Forestry and Road weather stations in British Columbia - data received at CMC, in old SA format. Data redistribution restrictions currently apply…should eventually be available in BUFR Co-operative network in Quebec (Province, Hydro-Quebec, etc), received at CMC, also redistribution restrictions…eventually in BUFR Montreal mesonet, including research wind profiler: under installation but operated by Universities, data not yet available and redistribution restrictions may apply…should be provided to USA profiler hub

31.
