The Korea Aerospace Research Institute (KARI) has collaborated with Jeollanamdo Agricultural & Extension Services and Chonnam National University to establish a ground observation tower for evaluating the value-added products (such as surface reflectance Normalized Difference Vegetation Index) improving algorithms of domestic development satellites (Korea Multi-Purpose Satellite-3, 3A 7). measurement tower, installed at Naju site (NGOS), constantly observes hyperspectral atmospheric information, providing advantage real-time algorithm validation improvement when satellite acquires images site. NGOS operates radiometer equipment (6 types), meteorological (5 sky (1 type), eddy flux (2 along web service display data processing. that is being operated can be utilized in various fields such carbon circle, agriculture, environment, atmosphere climate change, addition products. This study aims introduce KARI user sharing highlight characteristics measured data.
