SHB/MFRSR/C1- Alignment
DataStreams:shbmfrsrC1.a0, shbmfrsrC1.b1, shbmfrsrC1.00, shbmfrsrC1.a1
Description:
This information is automatically generated from a data base. There may be errors in the 
measurement names or measurement names for certain data streams may not as yet have been 
loaded into the data base.
	 Shadowband not	shading.  Ran mfr_loc at 19:10.	 Adjusted azimuth +3 degrees so that 
shadowband would shade diffuser. The sun breaks through the clouds only very occasionally, so 
it is difficult to check shadowband and very difficult to check alignment with true 
north which requires the sun to be casting shadows at local solar noon.	Diffuse	and direct 
irradiance should be considered bad in this period. Shadow band did	not shadow the sensor 
entirely.	 Only global values can be trusted. Instrument was re-aligned.
