The climate tab shows the climate details for each block and is the place to add snowfall.
Advice
- Draw blocks to get climate for that location
-
When possible use nearest town for climate profile (under farm settings)
NIWA climate data
Using a NIWA climate dataset, OverseerFM uses monthly temperature, PET, rainfall and sunshine hours in 500 square metre grids across New Zealand. This data represents an average taking into account the different weather conditions over 30 years (1991-2020).
Using a long-term climate makes it possible to compare the effect of changes in farm management rather than reflecting changes in the weather each year. This then allows comparisons with potential future management practices to inform farm planning.
NIWA makes no representations or warranties regarding the accuracy, completeness or fitness for the purpose of the data used. Any reliance on or other use of the data by a third party is entirely at the third party’s own risk. NIWA accepts no liability for any loss or damage, whether direct or indirect, consequential or otherwise arising from the reliance on or use of the data.
OverseerFM climate
Each block is assigned monthly climate data based on its location if it has been drawn. If the block has no location (is not drawn), then the farm’s location is used. All farms must define a location. Although not recommended, latitude and longitude can be entered to override the location used to lookup climate data when the block is created. The block location provides monthly data. The region set for the farm determines how the model works out daily rainfall and PET values.
Each block’s monthly climate is summarised to an annual value that is displayed under the climate tab - there is no ability to enter or edit a blocks climate manually.
Snowfall
The monthly-average NIWA precipitation data includes all forms of precipitation including snowfall.
