When blocks are drawn, the annual rainfall, PET (potential evapotranspiration) and temperature for that block are auto-populated using a 30-year climate data set from NIWA based on the block’s location.
The climate data is gridded at a 500m scale and so different Blocks may have different climate data based on their location.
If multiple non-contiguous areas of land are drawn for a single block, the climate for each piece of land is taken and then averaged proportionally based on the area of each piece.
Although not recommended, latitude and longitude can be entered to override the block location data. If this is done, the latitude and longitude point should be taken from the centre of the block area on google maps. It is not accurate to use the same latitude and longitude for different blocks.
