A sensitivity study of weather data inaccuracies on evaporation duct height algorithms

Radio Science, 1991
The sensitivity of five evaporation duct height algorithms to errors in shipboard meteorological data is examined, and the algorithms are intercompared. The data set used was generated parametrically so a large variation of environmental conditions could be considered.

PCR Model: Optimization of Evaporation Duct Height Prediction Based on Principal Component Regression

2020 IEEE 5th International Conference on Signal and Image Processing (ICSIP), 2020
Evaporation duct is an abnormal refraction atmospheric structure frequently appearing on the sea surface. Accurately obtaining the evaporation duct height (EDH) has significant effects on the effective application of electromagnetic system equipment. Aiming at the problems of large error and strong data dependence of current evaporation duct prediction

A preliminary study on the application of remotely sensed SST in locating evaporation duct height

SPIE Proceedings, 2012
Refractivity happens due to stratification in the lower boundary layer over oceans due to variability of moisture, temperature, wind and sea surface temperature which collectively may lead to generate evaporation duct. The evaporation duct has a significant impact on the spread of electromagnetic waves in the atmosphere over oceans both from the ...

Evaporation duct height measurements in the Mid-Atlantic: Final Report

2013
This is a report on atmospheric boundary layer measurements made aboard the USNS Kane in February and March of 1978. The data has been analyzed to obtain Monin-Obukhov similarity parameters and EM propagation properties using bulk, profile and turbulence data.
