Meteorological Products of Geo-KOMPSAT 2A (GK2A) Satellite

摘要

This special issue of APJAS contains nine papers of retrieval algorithms for Geo-KOMPSAT 2A (GK2A) meteorological products. K. Park et al. and J. Jee et al. present the development of the sea surface temperature and current vectors, and the aerosol detection retrieval algorithms for geostationary satellite data, respectively. M. Ahn et al. and K. Han et al. present the evaluation of atmospheric profile retrieval algorithm and NDVI estimation for GK2A satellite, respectively. K. Han et al. documents the improvement of 6S look-up-table based surface reflectance employing minimum curvature surface method. S. Hong and K. Lee et al. present the infrared soil moisture and upward longwave radiation retrieval algorithms for GK2A satellite, respectively. K. Min et al. present the improvement of the rapid-development thunderstorm algorithm for GK2A satellite. National Meteorological Satellite Center (NMSC) of Korea Meteorological Administration (KMA) has been operating the first Korean geostationary meteorological Satellite, named of Communication, Ocean, and Meteorological Satellite (COMS) since 27 June 2010 and retired it in March 2020. During its almost 10 years of successful career, COMS has operationally provided the 16 derived products which have used for the monitoring of severe weather phenomena including tropical storms, deep convective clouds, fronts, fog, aerosols such as Asian dust and utilizations in the numerical weather predictions models. In order to continue satellite observations for the follow on mission of COMS, NMSC started the second geostationary meteorological satellite project in 2011, so-called GK2A and its ground segment projects in collaboration with Korea Aerospace Research Institute (KARI) and Korea Electronics and Telecommunications Research Institute (ETRI). After successful launch on 5 December 2018 and in orbit test lasted about 8 months, the GK2A is commissioned since 25 July 2019 with the Advanced Meteorological Imager (AMI) of 16-channel imager like the Japanese Himawari-8 and the United States GOES-16 satellites launched in 2014 and 2016, respectively.
