ALIEVA The problem of optimizing the measurement of the total amount of water vapor in the air above the marine test site is considered and solved. The measurements were optimized according to the information criterion, taking into account the fact that external radiation coming from the coastal zone of the continent distorts the result of measuring water vapor in the air above the marine test site. Based on the analysis, a transcendental equation was derived, the solution of which made it possible to calculate the best length of the route along the test section from the sea to the shore, where the maximum amount of measuring information can be generated. Keywords: water vapor, optimization, coastal zone, measurements, information. DOI: 10.25791/infizik.2.2022.1253 Pp. 22-27.
