This International Standard proposal specifies technical requirements and evaluation method for temperature correction on temperature measurement in radiosonde due to solar radiation in sounding experiment. This International Standard is applicable to the correction of temperature measurement traceable to SI unit in radiosonde boom sensors according to variations of pressure and air speed under the simulated conditions of upper air. This proposed standard will mainly provide Terms and definitions Technical specification for test instrumentations. Test procedure of solar correction according to pressure and air speed. Uncertainty evaluation of the test procedures.
