Points in blue are for the first month of the project, when probes may have been settling (actually, mostly not too bad). Arguably, these values may be ignored. Points in green are for tsoil>5C, when soil should not have ice. The line is the expected variation of Cvsoil with Qsoil (4.184 J/kgK for 100% soil moisture by mass) with no dry soil heat capacity. Actual values should fall along a line parallel to (and above) this line.
