Precipitation

precipitation loads liquid, solid, or total precipitation forcing. It is a meteorological input for hydrological preprocessing and a diagnostic context for recharge and runoff interpretation.

Accepted sources

• custom

• sim2

Minimal example

[[data.precipitation.sources]]
source = "sim2"
components = ["total"]
extent = "watershed"

Checks

• components accepts liquid, solid, and total.

• Date coverage and units should be checked before comparing with recharge or runoff.

Visual check

Fig. 170 The right panel shows the kind of monthly total that should be inspected for SIM2 precipitation before it is compared with recharge, runoff, or solver budget terms.

Precipitation Source: custom

Use source = "custom" for local precipitation rasters, NetCDF files, or station-derived series.

[[data.precipitation.sources]]
source = "custom"
path = "data/precipitation/precipitation.nc"
components = ["total"]
source_unit = "mm/day"

Check component naming, units, period coverage, and spatial support before the data are used in hydrological preprocessing.

Precipitation Source: sim2

Use source = "sim2" to retrieve SIM2 precipitation fields.

[[data.precipitation.sources]]
source = "sim2"
components = ["liquid", "solid", "total"]
extent = "watershed"

Inspect the climatic summary to verify that the requested period and selected components are available.

Provider replay

Fig. 171 The monthly precipitation panel is the first provider replay to inspect before comparing precipitation with recharge, runoff, or solver budgets.
