Detailed Description

Environmental responses relevant for production of a tree species on resource unit level.

SpeciesResponse combines data from different sources and converts information about the environment into responses of a species. The spatial level is the "ResourceUnit", where homogenetiy of environmental factors is assumed. The temporal aggregation depends on the factor, but usually, the daily environmental data is aggregated to monthly response values (which subsequently are used during 3PG production). Sources are:

• vapour pressure deficit (dryness of atmosphere): directly from climate data (daily)
• soil water status (dryness of soil)(daily)
• temperature: directly from climate data (daily)
• phenology:

  Phenology, combines several sources (quasi-monthly)

• CO2:

  See also

  SpeciesSet::co2Response() based on ambient CO2 level (climate data), nitrogen and soil water responses (yearly)

• nitrogen: based on the amount of available nitrogen (yearly)

response calculation called during water cycle calculates minimum-response of vpd-response and soilwater response

calculate responses for VPD and Soil Water.

Return the minimum of those responses

Parameters

vpd	vapor pressure deficit in kPa

Returns

minimum of soil water and vpd response
