When ice accumulation occurs but does not meet the measurement standard, data representation is when the frozen soil depth exceeds the instrument scale range, it is expressed as 998xxx, where xxx is the maximum scale, in centimeters (cm).
When the frozen soil depth is less than 0.5cm, the upper and lower limit depths of the frozen layer and the maximum frozen soil depth are displayed.
When there is no weather phenomenon, the data recorded for daily weather phenomena are displayed. Industry Standard Information Service Platform

Ice accumulation on electric wires
Weather phenomena
Ice accumulation diameter, thickness, weight of electric wires
Upper depth of frozen layer, lower depth of frozen layer, maximum
Deepth of frozen soil
Daily weather phenomena records
Special characteristic values of meteorological elements (continued)
Characteristic values
999990
998xxx
999990
When ice accumulation occurs but does not reach the measurement standard, the data is expressed when the frozen soil depth exceeds the instrument scale range, it is expressed as 998xxx, where xxx is the maximum scale in centimeters (cm).
When the frozen soil depth is less than 0.5cm, the upper and lower limit depths of the frozen layer and the maximum frozen soil depth are expressed.
When there is no weather phenomenon, the data recorded for the daily weather phenomenon is expressed. Industry standard information service platform
