cosmicsense.core.D86(r, theta, press, Hveg, rhob, p0=8.321, p1=0.14249, p2=0.96655, p3=0.01, p4=20.0, p5=0.0429)

Penetration depth, or rather the depth within which 86 % of neutrons probed the soil.

Based on Koehli et al. (2015) and Schroen et al. (2017).

Parameters

• depth (float or 1d array of floats) – depth (cm) for which a weight should be returned

• theta (float or array of floats) – Average volumetric soil moisture (m3/m3) in the footprint

• press (float) – Barometric pressure (hPa)

• Hveg (float) – Vegetation height (UNIT???)

• rhob (float) – Soil bulk density (kg/l)

• - p5 (p0) – Parameters

Returns

output – Penetration depth (cm)

Return type

float or array of floats of shape (len(r), len(theta)), squeezed
