Subject:	SGP/MFRSR/E15 - Sun obscured by trees in late afternoon
DataStreams:	sgpmfrsrlangleyE15.c1, sgpmfrsrlangplotE15.c1, sgpmfrsrE15.b1, sgpmfrsrE15.00, sgpmfrsrE15.a0
Description:	The site is relatively close to a treeline to the west. In the late afternoon the sun sets below the trees. Depending on "your" point-of-view this is either just a feature of the data with this site, or it's a problem to be identified and dealt with. Affected data varies, but is typically about the last 30 minutes before the sun descends below the mythical horizon.
