For this reason, there are considerably fewer TAF locations than there are airports for which METARs are available. TAFs can be more accurate than numerical weather forecasts, since they take into account local, small-scale, geographic effects. Today, according to the advancement of technology in civil aviation, the TAF is sent as IWXXM model. [2]
