NZ Guidelines and Recording Standards for Weather, Snowpack and Avalanche Observations (2011, NZ)
Published by the Mountain Safety Council
Continuous information about the weather, snowpack condition and avalanche occurrences is essential for making decisions about avalanche safety in mountain operations including ski areas, guiding operations(heliskis or ski touring) and road safety operations.
Longer term, data is also required for hazard studies, the development of avalanche forcasting techniques and control programmes. Uniform methods of observations and terminology assist at least for the exchange of information between different operations.
These guidelines are the standard for New Zealand.
