c. Electrical contact problem on Vpile (unlikely, but should be checked)

d. Heat going into latent heat of fusion (melting mixed-phase moisture), rather than sensible heat (can partly check by looking at warm periods \-\- a new idea for me). \[The results of this check are not very convincing \-\- see below plot.\] |
This is closer than I've been before with this comparison, but I still have a long way to go.
Attached is my current comparison plot for each of the 9 soil sites after filtering the statistics for:
- good Tau63 and Vheat values
- rerun of covars over first half of the data
- removing qsoil values when tsoil<0C
Points in blue are for the first month of the project, when probes may have been settling (actually, mostly not too bad). 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 (and above) this line.
