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.
Suggestions:	Because the magnitude of the error is less than the uncertainty associated with the measurements, a correction is not recommended.
