With most of the satellite sites reporting, started looking at a few variables:

  • T has been below freezing most of the time, with a low at CC of -22C earlier in the week
  • RH has been near 100% a lot recently with snow.  Note several sites reporting RH a bit over 100%, which is not unusual for us.  I haven't worked out if this would be due to RH with respect to ice...
  • Maximum speeds were 10m/s last week, though often below 1 m/s.
  • Pressures track each other and are in the correct order with station height.  The topography in this valley is somewhat deceptive:  From high elevation to low, the order is LC, CC, DC, PC, MH, UP, PRS, MW, SH, DCS.
  • Rsw.out is at least 50% of Rsw.in this week, and sometimes much higher.  A good indication of snow on the ground!
  • ldiag often is close to 1 for some sensors.  This would indicate that heating/Teflon tape isn't completely effective.  We'll have to check/work on this.  CSAT.mw is always 1 (not working).
