Subject:
NSA/SURFSPECALB/C1 - Data processing problem
DataStreams:nsasurfspecalb1mlawerC1.s1, nsasurfspecalb1mlawerC1.c1
Description:
An intermediate process, surfspecalb_transform, of the surfspecalb1mlawer VAP incorrectly 
treated its input datastream (intermediate datastream surfspecalbmfrsr.c0) as it had a 
bin alignment equal to the end of the bin, but it was actually the middle of the bin.  The 
result was a shifting of the values with respect to time 10 seconds to the left.  The 
impact on the primary measurement, spectral albedo, was considered to be less than the 
uncertainty of that measurement.  

The problem occurs for all measurements dimensioned by time.
