Extraction and Analysis of Temperature data from COSMIC of Pacific Occultation

Abstract

With the increase of human demand for natural climate research, climate monitoring technology has been greatly developed, and the occultation technology proposed in the field of surveying and mapping provides a more accurate and effective data source for meteorology research. With the destruction of the earth’s ecosphere by pollution, the global climate change has a great impact on human life, so the research on meteorology has been paid more and more attention. The data obtained from GPS radio occultation observations have also become one of the key data sources to record the temperature changes of the atmosphere in tropical regions. The extraction and analysis of temperature data in the western Pacific are very essential. At the same time, it plays an crucial role in China’s climate prediction and disaster warning. It is hoped that by reading the occultation data of the western Pacific in 12 months in 2014, and drawing the isoline map of the lunar season and seasonal temperature values, the change law of global and western Pacific temperature with longitude, latitude and altitude can be analysed.
