We have done the following:

1> cleaned all radiometer domes. |
Decided simply to breath on the domes and wipe off the condensation. |
Order was Rsw.in Rlw.in Rsw.out Rlw.out. |
The sun was shining during this period, so the effect of cleaning should be measurable |
. All domes looked pretty clean before and after. . ?\[PS: have looked at the data. Haze made the radiation somewhat variable, so my best estimate is that cleaning changed Rsw.in by 2--10 W/m2. Not very much.\] All domes looked pretty clean before and after. (2:20pm) |
2> As per the task list, disinterred (at a cemetary!) the single Tsoil to check/correct its orientation. Found that it was nearly horizontal at about 2cm depth. Reinstalled it at an angle that I eyeballed to put the sensor from 1--6cm depth. Before doing this it read 0.3 C, after 0.81 C. Note that these temperatures are slightly above freezing. I noted a thin (~1cm) crust of frozen soil, but underneath definitely wasn't, which all is consistent. I should also note that there was about 10cm of snow covering the whole area that I attempted to replace when I finished. Finally, I note that we first unplugged the TP01 while determining which wire was which. Thus, its values reset to 0, but later appeared to be okay. (2:32PM)
