A special satellite-radiosonde colocation program

"This colocation system matches satellite retrievals of layer temperature and precipitable water with a selected set of 20 radiosonde stations. This preselection of radiosondes makes this system different from other colocation systems. Its advantage is that, when combined with a horizontal analysis of the local retrievals, it enables attention to be focused on areas (e.g., oceanic) of special interest to NMC and does so with a better accuracy and a higher rate of colocation than is possible when reasonably small space windows (e.g., 100 km) are demanded from conventional colocation systems. The disadvantages are that retrieval paths (e.g., "clear column," "N*," and microwave) are blended to some extent, and also that it cannot be used to determine horizontal correlations of satellite errors"--Page 1.
