Use HOBO weather sensor data to calculate evapotranspiration and understand water loss
Why is Evapotranspiration (ET) important?
The primary component of hydrologic budgets, evapotranspiration (ET), the sum of evaporation and transpiration from plants, reflects the degree of water loss into the atmosphere, which is critical information when determining irrigation watering needs, groundwater supply levels, drought patterns, and other environmental impacts related to water budgets.
