Radiation properties, change during drying

Discolorations caused by the drying process are those which actually occur during drying and are mainly caused by non-microbial factors [113], Many environmental factors such as solar radiation, moisture and temperature cause weathering or oxidative degradation of wooden products during their normal use these ambient phenomena can eventually change the chemical, physical, optical and mechanical properties of wood surfaces [114],... 

As drying proceeds, the material that is dried suffers a change in its radiation properties, increasing its reflectivity, and consequently lowering its absorptivity at low water contents. It is then possible to change adequately the temperature of the emitter in order to improve the absorption of radiation during drying. 

The statistical collection and representation of the weather conditions for a specified area during a specified time interval, usually decades, together with a description of the state of the external system or boundary conditions. The properties that characterize the climate are thermal (temperatures of the surface air, water, land, and ice), kinetic (wind and ocean currents, together with associated vertical motions and the motions of air masses, aqueous humidity, cloudiness and cloud water content, groundwater, lake lands, and water content of snow on land and sea ice), nd static (pressure and density of the atmosphere and ocean, composition of the dry ir, salinity of the oceans, and the geometric boundaries and physical constants of the system). These properties are interconnected by the various physical processes such as precipitation, evaporation, infrared radiation, convection, advection, and turbulence, climate change...
