Atmospheric Correction Research at Haystack
The space geodetic techniques of Very Long Baseline Interferometry (VLBI) and the Global Positioning System (GPS), whose capabilities have been significantly enhanced in order to make accurate studies of the solid earth, are now recognized for their potential contributions to atmosphere research in both weather prediction and climate. The observations of both techniques are affected by the additional propagation delay through the neutral atmosphere, and it is this excess delay that provides information on the amount of water vapor in the atmosphere that is of such importance to the meteorologists.
