site logs

03 Sept 2007, Ken I.

  • Site in good shape
  • SR50 looks okay, working, measured distance of 145 cm to ground surface
  • North fence run needs another post on future visit.
  • Solar panel wires exposed, need "plates" or other protection
  • Replaced SR50M-45 new s/n c4794 old s/n c4945
  • wired rad/snow pole turnbuckles
  • remove old HMP45C s/n B0110063, new s/n c1410038
  • Secured solar panel wires

    • measured height: 147 cm
  • installed new K&Z radiometer:
    • model: NR-LITE-L 16368-9, 40-feet
    • s/n: 051999
    • sensitivity constant: 14.1 uV/W-m^2
    • (old sensor was s/n 052069)
    • measured height: 87 cm centerline to ground surface
    • radiation sensor wiring: 4H-WHT, 4L-GRN, G-CLR
  • tightened SR50; still 147 cm
  • edited program
    • changed snow depth constant from 200 to 147 cm
    • changed net rad coeff from 14.6 to 14.1
