How would frequent lightning from cloud-to-ground and cloud to air in the vicinity of the observation be encoded?

The correct encoding of frequent lightning from both cloud-to-ground and cloud-to-air in the vicinity of the observation is accurately represented by the chosen answer. The abbreviation "FRQ" indicates that the lightning activity is frequent.

The terms "LTGCG" and "LTGCA" are essential components of this encoding. "LTGCG" stands for cloud-to-ground lightning, while "LTGCA" denotes cloud-to-air lightning. By combining these terms after the "FRQ," the encoding clearly communicates the presence of both types of lightning occurring frequently in the vicinity.

Including both "LTGCG" and "LTGCA" in the encoding is important because it provides comprehensive information to pilots and meteorologists about the specific lightning conditions they may encounter, aiding in the assessment of flight safety and weather conditions.
