Chlorophyll meters typically output an index that isnon-linearly related to chlorophyll concentration (e.g.,CCI or SPAD). The MC-100 outputs an estimate of actualchlorophyll concentration in units of μmols per m² of leaf surface. Thus, changes in the displayed output reflect true changes in chlorophyll concentration. For example, doubling a measured chlorophyll concentration represents an actual ...

Net radiation is the sum of the four components shown to the left (incoming shortwave, outgoing shortwave, incoming longwave, outgoing longwave). Incoming shortwave incident on the surface is either reflected or absorbed by the surface material, and longwave radiation is emitted from the surface and emitted from the molecules of air in the atmosphere. Typical clear sky summer fluxes over grass ...
