| Notes: (1) Parameter deprecated - See Regulation 92.6.2 and use another parameter instead. (2) It is recommended not to use this parameter, but another one with a more descriptive unit. (3) Parameter deprecated. Use another parameter in parameter category 3: Soil Products instead. (4) Statistical process 1 (Accumulation) does not change units. (5) For parameter 38 (Parameter category 0), ice volume is expressed as if the ice content were melted to liquid water and then its volume measured in the liquid state. This may be understood in the same manner as water equivalent snow depth. (6) The listed units for this parameter appear not to be appropriate for evapotranspiration. Instead, it is recommended to use parameter 39 with statistical process 1 (accumulation) in order to report evapotranspiration in units of kg m-2. (7) A C4 plant is a type of plant that uses a specific photosynthesis mechanism (C4 photosynthesis) in order to avoid photorespiration. Other types of plants are C3 and CAM. (8) This parameter can be used with templates for chemical constituents to specify a chemical species if needed, for instance: Net ecosystem CO2 exchange flux or Net ecosystem CH4 exchange flux. |
