The calculation of 10-daily statistics over the entire archive, such as the long term averages, minimum, maximum, standard deviation and count, is done for each crop indicator and for each individual geographical feature. A dedicated software package called LTA_YIELD is developed to do all calculations.

For the following basic parameters average values are calculated:

  • Potential above ground biomass
  • Water limited above ground biomass
  • Potential storage organs biomass
  • Water limited storage organs biomass
  • Potential Leaf Area Index
  • Water limited Leaf Area Index
  • Crop development stage (DVS)
  • Relative soil moisture
  • Total water consumption
  • Total water requirement
  • volumetric soil moisture content in rooted zone (FSM)
  • volumetric soil moisture content in not rooted zone (FSMUR)
  • Leaves died by cold
  • Run off
  • Soil evaporation
  • Loss to subsoil

The 10-daily statistics based on weather observations is stored in tables:
