Spatial analyses of crop development stage of winter wheat on June 10th 2011 (dekad 16).
Average temperature around flowering of winter wheat, starting 10 day's before until 10 day's after flowering (crop development stage = 100).

Crop indicators and yield forecasts are produced with 10-day intervals. They presented as 25x25 km grid cells or administrative regions. Crop indicators can be presented as departures from normal (other years or long term average), expressed in relative terms or absolute values. Assessments of the dates of occurrence of specific phenological stages are likely to be imprecise and probably only suitable to be expressed in relative terms such as departures from normal or ‘very late, late, normal, etc.’ (Vossen and Rijks, 1995).

Marsop3 viewers

The Marsop3 viewers are developed to analyse the available datasets. The analyst version has full functionality and can access all datasets. The web version serves the 'outside' world with a selection of datasets and limited functionality. The data can be analysed in spatial (maps) and temporal resolution (graps). Data are available from 1975 onward.

Indicators available at EMU and administrative (nuts) regions

  • 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
  • Total water requirement
  • Total water consumption
  • Relative soil moisture
  • Crop development stage

Indicators available at 25x25 km grid resolution

On a 25x25 km grid resolution the above mentioned indicators are extended with indicators that are used for generating risk maps of critical crop development stages (such as sowing, flowering, ripening and maturity). Some of these indicators combine a critical crop development stage with extreme weather events.

Available indicators:

  • All above indicators
  • Precocity
  • Number of heat waves around crop development stage
  • Longest heat wave period around crop development stage
  • Rainfall around crop development stage
  • Rainfall around sowing
  • Temperature around crop development stage
  • Temperature around sowing
