Dynamics of Heat Storage in Evapotranspiration Estimate.

One of the widely discussed reasons for a lack of surface energy balance closure when using eddy covariance is neglect of storage term elements. Storage as related to the surface energy balance refers to all heat stored below the observation level of eddies. It represents the sum of several components, including heat stored in soil, plants, air between plants, and through photosynthesis. The magnitude of storage may be significant relative to net radiation, making storage an important part of the available energy for evapotranspiration. At an irrigated sorghum field in Bushland, TX, during summer 2014, micrometeorological measurements were taken that will allow for storage elements to be calculated on sub-hourly, hourly, and daily time scales.
