Forest Evapotranspiration and Energy Flux Partitioning Based on Eddy Covariance Methods in an Arid Desert Region of Northwest China

Figure 4

The annual course of daily average net radiation (), latent (LE), sensible (), and soil heat fluxes, and the evaporative fraction (EF). (a) to (f) represent six periods: (a) the soil-frozen period; (b) the soil ablation period; (c) the germination, flowering, and leaf expansion period; (d) the vibrant growing season; (e) the leaf senescence period; and (f) the early soil-frozen period.
