What is indicated by the weather code GS?

The weather code GS indicates "Small Hail/Snow Pellets." This code is used in meteorological observations to specify a type of precipitation that consists of small, round pellets that resemble hail but are composed of ice or snow. Distinguishing small hail from snow is important for aviators and drone operators, as it can affect visibility and aircraft performance. Understanding these weather codes is vital for evaluating weather conditions before a flight, ensuring safety and operational planning.
