We have done the following:

Wiki Markup1> cleaned all radiometer domes.&nbsp;   Decided simply to breath on the domes and wipe off the condensation.&nbsp;   Order was Rsw.in Rlw.in Rsw.out Rlw.out.&nbsp;   The sun was shining during this period, so the effect of cleaning should be measurable.&nbsp;   ?\[PS: have looked at the data.&nbsp;   Haze made the radiation somewhat variable, so my best estimate is that cleaning changed Rsw.in by 2--10 W/m2 out of 380 W/m2 and Rlw.in not at all.&nbsp;   Not <too> bad.\]&nbsp;   All domes looked pretty clean before and after.&nbsp;   (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)
