View source for Calculation of long term average crop indicators

{{Scientific}}
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:
*{{Object|SIMYIELD_EMU_LTA}}
*{{Object|SIMYIELD_GRID_LTA}}
*{{Object|SIMYIELD_REGION_LTA}}

The 10-daily statistics based on forecasted weather is stored in tables: 
*{{Object|SIMYIELD_HIS_EMU_LTA}}
*{{Object|SIMYIELD_HIS_GRID_LTA}}
*{{Object|SIMYIELD_HIS_REGION_LTA}}
