DataStreams:	sgp1440smosE20.b1, sgp1smosE20.b1, sgp30smosE20.b1
Description:	Recently, the RH readings at this facility have been very high (sometimes approaching 110%) in saturated conditions. This is especially prevalent from 01/03/2005 through 02/07/2005.

DataStreams:	sgp1440smosE20.b1, sgp1smosE20.b1, sgp30smosE20.b1
Description:	Wind speed data is artificially low during the listed time periods. Icing conditions caused the reduction in speed compared to nearby sites.
