It is quite easy for a pilot to casually accept routine (METAR) or special (SPECI) surface observations at face value. While it is especially important to be wary of automated surface observations, it is imperative to verify the integrity of ALL observations you may use. One approach is to employ the use of a "buddy check." In other words, compare any pertinent surface observation to others around the same general vicinity. Are the observations reasonably consistent with one another? Or is there one that tends to stand out as being different? In this workshop, we’ll use the buddy check along with a Skew-T log (p) diagram to help identify an erroneous surface observation.
