Subject: | SGP/EBBR/E27 - Soil Heat Flow #4 Incorrect |
DataStreams: | sgp30ebbrE27.b1, sgp15ebbrE27.b1 |
Description: | Soil Heat flow sensor #4 outputs were often very small negative numbers. See below for a work-around. |
Suggestions: | Recalculate the average soil heat flow (ave_shf), latent heat flux (e), and sensible heat flux (h) using only soil sets 1, 2, 3, and 5, as follows: ave_shf = (g1 + g2 + g3 + g5)/4 e = -(q + ave_shf)/(1 + Bowen) h = -(q + e + ave_shf) where q is net radiation and Bowen is the Bowen ratio. |
