Subject:	SGP/SMOS/E4 - E4 SNOW DEPTH DATA QUESTIONABLE
DataStreams:	sgp30smosE4.b1, sgp30smosE4.a1, sgp1440smosE4.a1
Description:	Snow depth data is questionable due to the sensor intermittently reporting values outside the manufacturers tolerances of +/- 25mm.
Suggestions:	Only use data that is within the tolerances.
