NSA/GNDRAD/C1 - Reprocess: Miscalibrated upwelling SW
DataStreams:nsagndrad20sC1.a0, nsagndrad60sC1.b1, nsaqcrad1longC1.c1, nsaqcrad1longC1.s1
Description:
On 7/20/2011 2211GMT Ops replaced the Gndrad upwelling shortwave instrument (PSP) but the 
calibration coefficients weren't changed until 07/25/2011 1842GMT.  The up_short_hemisp 
data will be reprocessed.

Old SN/cal:31294F3 / 113.59 W/m2/mV
New SN/cal:32014F3 / 116.43 W/m2/mV

Apply the following correction factor to each up_short_hemisp data point during this time 
period: new value [W/m^2]= old value [W/m^2]* (116.43/113.59)

DataStreams:nsaskyrad20sC1.a0, nsaskyrad60sC1.b1, nsaqcrad1longC1.c1, nsaqcrad1longC1.s1
Description:
On 7/20/2011 starting 2229GMT ops replaced the Skyrad shortwave instruments (PSP/8-48/NIP) 
corresponding to the datastreams (down_short_hemisp, down_short_diffuse_hemisp, 
short_direct_normal) but the calibration coefficients weren't changed until 07/25/2011 1842GMT.  
Data will be reprocessed.

Longwave data are unaffected.

Apply the following correction factor to each instrument data stream below during the 
specified time period:

   correct value [W/m^2]= old value [W/m^2] * (111.44/119.23)
down_short_diffuse_hemisp 7/20/2011 2229GMT to 7/25/2011 1843GMT:
