In the Arctic and sub-Arctic, up to half of annual net ecosystem exchange (NEE) occurs during the snow season. Subnivean soil respiration can persist at a greater rate when the overlying snowpack has a lower thermal conductivity, and the rate of photosynthetic uptake at the start and end ...
3. Species distribution and uses of vitamin A1/A2 chromophore exchange 4. Environmental factors controlling the A1/A2 ratio 5. The enzymatic mechanism and transcriptional control of vitamin A1-to-A2 conversion 6. The extent of red shift upon switching from A1 to A2 is correlated with λmax 7...
3.1.3. Temperature Surface temperature is a critical variable in the surface energy balance that links the atmospheric and sub-surface processes. Typically, either sensors are placed on the surface in an effort to match surface radiative properties or radiative surface temperatures are measured ...
