Description: | DATA REPROCESSED and CORRECTED:
No data were collected from 6/7/2006 0000 to 6/14/2006 1612 due to hardware problems. When
data resumed on 6/14, all calibration coefficients and serial numbers were for different
instruments, possibly due to incorrect program loaded on storage module. Correct program
reloaded by PM/CM Techs on 7/12 1830 GMT. The data were reprocessed to apply the correct
calibration coefficients for shortwave and longwave data.
The data were archived in September 2016. Please retrieve the reprocessed data for use in
your analysis.

Shortwave data can be corrected with a simple multiplier as shown below. Longwave data
must be reprocessed from temperature and netIR data.
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 109.52 110.31
up_short_hemisp 111.61 109.80

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.
