@ Site A: Replace Snow #1 (ID 7)
@ Site A: Look at Heat Flux Pit #2... it is reading 0mV, may have broken in the ground)
@ Site B: Look at Heat Flux Pit #1 & #2... both reading 0mV)
At each site:
- Level Radiometer (phillips screwdriver needed)
- Replace Desiccant in radiometer (phillips screwdriver needed, anti-corrosion grease)
- add Desiccant to instrument box
- clear snow from precip gage & level (torpedo level, snow shovel, 5/16" nut driver needed)
if time allows change out dreamplug

fly up the 11th, arrive in the evening
morning of the 12th, one person puts the base together at NARL
grab some flex conduit for cable protection at base of tower (camera cable, radiometer cable)
in barrow grab a piece of trail mat to put under the tower
two people head out to BEO to site tower, identify tower location (using gps setup / tablet & power cable)
shovel snow at tower base & guy wire anchors
use gps to site tower and guy points (so as to miss frozen LCP etc)
third person brings tower and anchor to cake eater pull off
afternoon of the 12th / the 13th: tower is raised
once we see how easy it is to lift we'll know how many people it takes to lift and drop
once tower is up Lily can visit the stations as time allows
change out snow sensor @ A
desiccant change out for radiometers
re-level radiometers
check level of precip buckets
look at those heat flux plates (see if a wire has come loose)
