ETP#

etp loads potential evapotranspiration. It can be passed to solver evapotranspiration packages when the flow process activates ETP forcing.

Accepted sources#

  • custom

  • sim2

Minimal example#

[[data.etp.sources]]
source = "sim2"
extent = "watershed"

Checks#

  • ETP should be non-negative before solver assembly.

  • Check time aggregation when ETP is applied to stress periods.

ETP Source: custom#

Use source = "custom" for local potential evapotranspiration forcing.

[[data.etp.sources]]
source = "custom"
path = "data/etp/etp_daily.nc"
source_unit = "mm/day"

Check units, period coverage, non-negative values, and stress-period aggregation before interpreting a solver response.

ETP Source: sim2#

Use source = "sim2" to retrieve SIM2 potential evapotranspiration fields.

[[data.etp.sources]]
source = "sim2"
extent = "watershed"

Use the climatic summary for pre-solver checks, then inspect water-budget terms after ETP has been activated in the flow configuration.
