  Methods for Variable RAD_SOL

  Li-Cor 200S total radiation sensor

  When a sensor is removed a new sensor will be placed in service immediately at that station. Because its constant will be different from the one removed, a new multiplier must be calculated for the 21X program and entered into it. The 21X multiplier is calculated as follows:

  For 200S Sensor: MULT=60/(0.100*uamps)

  The multipliers must be entered into the datalogger program in the proper location. Changes to the program must be noted in the Station Log and on all "current" listings of that station's 21X program.

  • Format: I

  Methods for Variable PAR

  Li-Cor quantum (190S) sensor

  Units are micro-einsteins per meter squared

  When a sensor is removed a new sensor will be placed in service immediately at that station. Because its constant will be different from the one removed, a new multiplier must be calculated for the 21X program and entered into it. The 21X multiplier is calculated as follows:

  For 190S Sensor: MULT=60/(0.604*uamps)

  The multipliers must be entered into the datalogger program in the proper location. Changes to the program must be noted in the Station Log and on all "current" listings of that station's 21X program.

• Units: degrees C

• Range: -20-40

• Format Information:
  
  • Start Column: 18

  Methods for Variable SOIL_T

  Temperature probe placed 10 cm below ground surface.
