QT-1050 wave temperature ratio system

Product Details

QT-1050 wave temperature ratio system is a system for studying energy balance (total loss of soil water evaporation and transpiration). Can directly obtain Bowen ratio (B), sensible heat (H) and latent heat (Le) parameters. Farmland ecosystems are located near the ground, and can be divided into soil layers and crop canopies. They are interfacial activity zones that sustain the three-phase material energy cycle conversion. In farmland ecosystems, the energy obtained from the outside world is mainly radiant energy used to expend depletion on farmland evapotranspiration, air heat exchange, heating of the soil, and a very small portion stored as photosynthetic energy. The distribution ratios and rules of net radiant energy in the system have been hot topics in modern farmland ecology, agricultural meteorology, and hydrology.

The picture is for reference only, the actual order shall prevail.
