Subject:
SIRS NIPs affected by condensation at E8, E11, E13, & E15
DataStreams:sgpsirsE15.a1, sgpsirsE8.a1, sgpsirsE11.a1, sgpsirsE13.a1
Description:
Comparison of data from the unshaded PSP to that derived from the 'direct
+ diffuse' (NIP + shaded PSP) indicated low values of the 'direct+diffuse' combination 
starting at sunrise and lasting for about an hour at E8, E11, E13 and E15.
Futher examination revealed that the NIPs were reading low and were likely
affected by condensation during this brief period. Weather conditions were
foggy over the area early that morning, and fog quickly dissipated after 
sunrise.
