NOAA-20 (N20/JPSS-1/J1) is the second satellite in the US NOAA latest generation Joint Polar Satellite System (JPSS), launched on November 18, 2017. NOAA is responsible for all JPSS products, including SST from the Visible Infrared Imaging Radiometer Suite (VIIRS). The L2P SST product is derived at the native sensor resolution (~0.75 km at nadir, ~1.5 km at swath edge) using NOAA's Advanced Clear-Sky Processor for Ocean (ACSPO) system, and reported in 10-minute granules in netCDF4 format, compliant with the Group for High Resolution Sea Surface Temperature (GHRSST) Data Specification version 2 (GDS2). SSTs are derived from Brightness Temperatures (BTs) using the Non-Linear SST (NLSST) algorithms (Petrenko et al., 2014). An ACSPO clear-sky mask (ACSM) is provided in each pixel as part of variable l2p_flags, which also includes day/night, land, ice, twilight, and glint flags (Petrenko et al., 2010). Only ACSM confidently clear pixels are recommended (equivalent to GDS2 quality level=5). Per GDS2 specifications, two additional Sensor-Specific Error Statistics layers (SSES bias and standard deviation) are reported in each pixel with QL=5. The ACSPO VIIRS L2P product is monitored and validated against quality controlled in situ data provided by NOAA in situ SST Quality Monitor system (iQuam) using another NOAA system, SST Quality Monitor (SQUAM). A reduced size (0.5GB/day), equal-angle gridded (0.02-deg resolution), ACSPO L3U product is also available, where gridded L2P SSTs with QL=5 only are reported. The v2.80 is an updated version from the v2.61 with several algorithm improvements including two added thermal front layers, reduced L2P SST data size, mitigated warm biases in the high latitudes, and improved clear-sky mask.

2010년에 발사된 천리안위성(COMS, Communication Ocean and Meteorological Satellite)은 지구적도상공 36,000km 고도, 동경 128.2°에 위치하여 기상관측, 해양관측, 통신서비스 등의 임무를 수행하는 우리나라 최초의 정지궤도 복합위성입니다. 천리안 위성은 5개의 기본채널 관측을 통해 16종의 기상산출물을 생산하며, 생산된 기상산출물들은 기상예보, 수치예보 및 기후변화 예측 등에 활용합니다. 생산주기: - 북반구: 매시 00, 15, 30, 45분 - 한반도: 매시 13, 28, 43, 58분 - 전구: 3시간마다 매시 15분 보유기간: 2011년 4월 ∼ 2020년 3월
