| Description: | During site corrective maintenance to resolve an Extended Facility data collection
problem, the SIRS.E12 datalogger was power cycled (1725 GMT). The datalogger reverted to an old
SIRS program with incorrect S/Ns and calibration coefficients for all instruments at
this station.
The data can be recalibrated as follows:
First divide value by incorrectly applied cal coeff (first number) then multiply by
correct cal coeff (second number)
down_short_diffuse_hemisp 107.27 118.68
up_short_hemisp 113.19 127.95
short_direct_normal 120.17 120.52
down_short_hemisp 118.46 102.11
up_long_netir 0.2747 0.2708
down_long_netir 0.2657 0.2435
Reapply cal coeffs below using up_long_netIR(uV), inst_up_long_dome_temp(K),
inst_up_long_dome_temp(K) using procedure described in SIRS instrument manual.
up_long_hemisp
k0 -23.4600 W/m^2\n,

Reapply cal coeffs below using down_long_netIR(uV),inst_down_long_dome_temp
(K),inst_down_long_dome_temp(K).
