Westford Water Vapor Experiment: Use of GPS to Determine Total Precipitable WaterVapor

摘要

The Westford Water Vapor Experiment (WWAVE) was designed to measure the temporaland spatial variability of the total precipitable water vapor (PWV) over an area defined by an approximate 25 km radius centered on the Haystack Observatory in Westford, MA. PWV is defined as the height of liquid water that would result from condensing all the water vapor in a column from the Earth surface to the top of
