Tropical Rainforests - Tropical Rainforests To be classified as a tropical rainforest, the area must receive at least 1300mm of rain per annum. True GPP is measured in terms of the energy produced per unit of area over a given time span, such as kilocalories per square metre per year. This figure is well above the average net primary productivity of many other biomes, with biomes such as temperate grasslands having only about 600g/m2/year. With more than 60 inches of rainfall a year, the tropical rainforest more than doubles the next closest biomes maximum amount of rainfall.
