This paper suggests a temperature guidance which must be addressed in the preparation of specifications for military equipment used in ocean/coastal environment of the Korean peninsula. It would often be costly to design materiel to operate under the most extreme environmental conditions ever recorded. Therefore, military planners usually accept equipments designed to operate under environmental stresses for all the time except a certain small percentage of the time. In this study, an 1-percent frequency of occurrence is recommended. Pohang and Shineiju are chosen to represent the hottest and coldest regions, respectively, based on surface weather observations among 28 costal regions from 1904 to 2015. The 1st and 99th percentile temperatures for Pohang and Shineiju are $37.7^{\circ}C$ and $-23.7^{\circ}C$, respectively. Diurnal cycles, including solar radiation, relative humidity and wind-speed are also provided.

This paper suggests a temperature guidance for requirements which must be addressed in the preparation of specifications for military equipment used in land applications in the Korean peninsula. In general, the equipment should be designed to operate during all but a certain small percentage of the time. Daegu and Yangpyeong are the hottest and coldest regions by month, respectively, based on surface weather observations over 132 regions from 1904 to 2014. The 1-percent high and low temperatures for land environment in the South Korea are $38.7^{\circ}C$, and -$29.0^{\circ}C$, respectively. This paper also presents the temperature values occurring for specified frequencies of occurrence during the most severe month. Diurnal cycles associated with the hottest and coldest top one-percent temperatures, including associated solar radiation, relative humidity, and wind-speed are provided.
