Subject:
Offset in Precipitable Water Vapor
DataStreams:sgp30wpdngpsX1.00, sgp30wpdngpsX1.c1
Description:
The precipitable water vapor (PWV) is offset 2-3mm low during this time
period. However, the offset does vary over this period of time. Dan Wolfe,
ETL, states that the offset was caused by a combination of a mapping 
function and the fact that they were not collecting or processing
satellite data below 15 degrees above the horizon. He further states
that the trends were still fine during this period.
