Send us your snow observations

Measurements of snowfall at low elevations around New Zealand are few and far between, and yet the data would be really helpful in understanding how snowfall occurs and quantifying snow-related risks.

For each location, send us your 10 snow depth measurements (in mm) and whatever snow water equivalent (snow density) measurements you made. Be sure to include a description of this location (e.g., in my garden, in a park) as well as a post code (address is optional and will be kept confidential). 

Also, make sure you include the location of the measurements and the date and time of observation.

What will happen to the data?
The data will be given to any scientific study that asks for it. No personal information such as personal details and address will be made available. 

If we have enough data, we'll develop a Google Map, shortly following the event, to share – it will be posted on this website.

We look forward to your wonderful, citizen-powered data!

Observation form

We've made an easy-to-use, simple form into which you can put your observations.
