SGP/SIRS/E13 -  Reprocessed and Corrected: incorrect calibrations

DATA REPROCESSED and CORRECTED: 

After a long data gap on 05/25/2005, presumably a power outage, short_direct_normal (NIP) 
was showing incorrect value as well as incorrect calibration coefficients in the data 
logger program. The SIRS. E13 data logger was power cycled (6/2/2005 GMT) and the correct 
program loaded into the SIRS data logger and storage module. The data during this time 
range were reprocessed to apply the correct calibration coefficients for Short_direct_normal 
data.

The data were archived in September 2016. Please retrieve the reprocessed data for use in 
your analysis.

--- ORIGINAL DQR DESCRIPTION ---
---------------------------------------------------


After a long data gap on 5/25/2005, presumably a power outage, the following datastreams 
were showing incorrect values as well as incorrect calibration coefficients in the 
datalogger program:
down_long_hemisp_shaded (downwelling PIR instrument)
up_long_hemisp (upwelling PIR instrument)
short_direct_normal (NIP instrument)

The SIRS.E13 datalogger was power cycled (6/2/2005 2200GMT) and the correct program loaded 
into the SIRS datalogger and storage module.

The data during this time range can be recalibrated as follows:
First divide value by incorrectly applied cal coeff (first number) then multiply by 
correct cal coeff (second number)
  short_direct_normal           120.28	124.58
  up_long_netir                 0.2386	0.2595
  down_long_netir               0.3052	0.2304

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	-18.3400 W/m^2\n,
	k1	0.2595 W/(m^2*uV)\n,
	k2	1.0380 unitless\n,
	k3	-2.7420 unitless\n,
	kr	0.0007044 K/uV\n,

Reapply cal coeffs below using down_long_netIR(uV),inst_down_long_dome_temp 
(K),inst_down_long_dome_temp(K).
  down_long_hemisp_shaded	
        k0	-11.6300 W/m^2\n,
	k1	0.2304 W/(m^2*uV)\n,
	k2	1.0190 unitless\n,
	k3	-2.4230 unitless\n,
