{{#category_index:L|local noise compensation (LNC)}} A technique for reducing time-variant but spatially invariant noise. Data at a base station are first stacked to remove time-variant noise. Time-variant noise at the base is then determined by subtracting the stacked value. The difference at a given time is subtracted from observations at nearby stations. See Stephen et al. (1991).
